AM3352: Custom board boot issue

Adam Gerken1

Part Number: AM3352
Other Parts Discussed in Thread: TPS650250,

Hey everyone, I have a custom board I've built, loosely based on the Smart Energy Gateway, using the TPS650250 and following the reset scheme which all appears to be working, the only other things on the board are a Marvel 1000Mbps PHY, and a BLE radio using UART. It doesn't appear to be powering up, I'm not seeing an 'CCCC' on the output terminal.

I'm trying to TFTP boot, and it doesn't seem to be doing anything, but I assume the Cs should come up whether the spl is loaded or not? I"m not really sure what is going on, I've never had an issue with the AM335x platform before, it's always been pretty easy to get booted. The PHY is Marvell, and appears to be coming up properly, I get a gigabit connection on the switch and see some basic traffic on Wireshark, but it appears the processor isn't booting at all, I don't get any DHCP entries or anything.

I can't share schematics publicly but I can share with a support person privately. This is a real headscratcher.

Thanks,

Adam

Hi,

The "C" characters are output on UART0 only if you have UART boot included in your SYSBOOT sequence. I suggest you start by following this guide: processors.wiki.ti.com/.../AM335x_board_bringup_tips

Ah, makes sense. I got the Cs on the console now by switching to a UART0 boot method. Now, I guess I'll just boot via UART instead of TFTP, I think I have the errata issue where I power the PHY up too early.

I compile my u-boot and try to boot it following the instructions here: https://processors.wiki.ti.com/index.php/AM335x_U-Boot_User's_Guide#Building_U-Boot

After I send the u-boot-spl.bin the Cs never start up again. Is there something special I have to do in order to enable UART in the SPL/u-boot?

I'm basically using the am335x_evm board, mux, board.h, defconfig, and config but without the EEPROM stuff, and just hard coding my board's options which are half based on the beaglebone black (RAM), half on the Smart Gateway(Power)... I don't need anything else in u-boot, the board just has another UART for BLE HCI, an RGMII port, and an eMMC I'll eventually transfer everything to and boot from.

Thanks Biser!

This is quite normal, SPL has been loaded and execution has passed to it. What you must do is send the u-boot.img file via YMODEM as fast as possible.

I think the real issue was that I was trying to use a vanilla am335x_evm build just to get something working to prove the SoC was up and running, and the SPL was failing due to the hardware being different. I think probably the EEPROM thing. Once I massaged u-boot to my board it seems to work fine. I can load the spl and u-boot via serial and everything looks good.

My next issue is getting the Kernel, dtb, and file system onto the board. I'm totally lost... I've been reading a million things the last couple days and nothing seems to address what I'm trying to do:

1) Load spl and u-boot via UART (working)

2) Load the kernel, dtb and FS from TFTP. I want to use DHCP to get an address, I think? I followed this: https://processors.wiki.ti.com/index.php/AM335x_U-Boot_User's_Guide#UART_2 and it doesn't work.

3) Partition and flash everything onto the eMMC that's on the board. I don't know if this is possible from u-boot, but that would probably easiest. Then I figure I can just boot u-boot via UART, format and partition the eMMC then load everything into it via TFTP then reboot from eMMC?

I'm really lost how to accomplish the last two steps, every single thing I've read does these completely differently and non of them work. The include/configs/"my-board".h copied from the am335x_evm.h file is a disaster with bootargs and env settings and I can't make heads or tails of it.

So you are getting to U-Boot prompt, and can enter commands there, correct?

Assuming you are really at U-Boot prompt, can you try to check basic network connectivity to see if you can get an IP address assigned:

setenv autoload no
dhcp

As for basic network boot U-Boot related info, your go to place should be this:

The Wiki docs are no longer maintained, and we are in the progress of migrating content into the official SDK doc I pointed to earlier, after which the Wiki will get turned off.

Then, our AM335x Linux SDK together with any of the supported EVMs should be able to serve as a reference platform for network boot.

So your end goal is to find some way to program the eMMC with U-Boot, the Kernel, and filesystem, and then only boot using eMMC, right?

If so, there are two ways you could do this:

Perform a network-based boot to Linux prompt. Then, use Linux to prepare/partition your eMMC, and program/copy everything you needed. Since you can mount the eMMC you have a lot of flexibility of what you can do here, or
Use U-Boot to load an eMMC image ("SD card image") over network/TFTP into DDR. Then, use U-Boot commands to program this image into eMMC. Can also be done piece by piece if the image is larger than available DDR.

There are various E2E posts covering both 1 and 2, it's just a question of preference which way you want to go.

Yes, that's correct. I have the SPL and u-boot up and runnning via UART with no problem. I can poke around, see the PHY is connected, get it's info via MDIO commands, etc. I can also see the eMMC. That's about all I care about for u-boot, I think.

I'll try that out. I think I tried it with no luck. It could be an issue with the PHY, I don't know. I'm using a Marvell PHY, I enabled the drivers in u-boot config, and I can probe it via u-boot commands, get the correct part number, and see that it has a link up at 1000Mb.

Yeah, exactly I need to get the images all on the eMMC and then boot from that. The boot order is set so the eMMC should go first, with UART0 later on, which is how I've been booting. I have a button to enable TFTP boot as well. Right now I'm thinking the easiest thing to do is just boot u-boot via UART, set up the eMMC, transfer everything to it via TFTP then reset and let the eMMC take over. Loading the kernel via UART takes like a half hour, which isn't ideal. The board has 256MB of RAM so it should be plenty to load everything into RAM, then write to eMMC.

I'll need to write a script to do all this automatically in a production environment... this product will likely be in the 1000's so I'm thinking it would be pretty easy to write a script to get u-boot loaded via UART, then run a u-boot script to take over from there.

I'm really not picky how it happens though, as long as I end up with a bootable eMMC.

Thanks for the help so far! I really appreciate it, I'm a hardware/firmware guy and this is my first real dip into Linux.

This is a great step as it indicates your DDR is working, and you have a console to work with - and a step where many struggle initially.

Make sure your server-side setup is good, by for example connecting a known-good board (such as a BeagleBone black) to the same Ethernet cable, and then try executing the same two U-Boot commands I pointed to earlier (setenv autoload no and dhcp).

Also you could do a quick Google and E2E search with the Marvell PHY part number to find designs where it might have been used successfully, and hints what might be missing configuration-wise, if anything.

For example, you may need to experiment/change the "phy-mode" setting in the device tree node associated with the PHY as per https://git.ti.com/cgit/processor-sdk/processor-sdk-u-boot/tree/doc/device-tree-bindings/net/ethernet.txt?h=processor-sdk-u-boot-2019.01

* "rgmii" (RX and TX delays are added by the MAC when required)
* "rgmii-id" (RGMII with internal RX and TX delays provided by the PHY, the
  MAC should not add the RX or TX delays in this case)
* "rgmii-rxid" (RGMII with internal RX delay provided by the PHY, the MAC
  should not add an RX delay in this case)
* "rgmii-txid" (RGMII with internal TX delay provided by the PHY, the MAC
  should not add an TX delay in this case)

Yes please don't do that. It might be okay for bench testing purposes but nothing else.

Yes that's how you can do it. Try looking into the "expect" / "autoexpect" tools in Linux, they can be very helpful in remote-controlling terminal-type interfaces in a robust manner.

This is step 1 of what I need help with. I'm totally lost on what a "good setup" is. The links you posted have a totally different method than the old wiki and neither of them seems to work. I can't get a valid IP address on anything I plug into the Ubuntu machine.

Also another thing I'm now totally confused about... does u-boot use device tree now? I see there are device tree files in u-boot but I never made or modified one, just the "old school" files ... board.c, board.h, defconfig, include/configs/board.h, etc. Now I'm reading about driver model and using dts in u-boot, but only bits and pieces are supported. I'm going to pull my damn hair out.

Andreas Dannenberg said:

No clue, the eMMC on the board is 4GB. I haven't even started down the path of how to make images...

To be honest, the documentation for all this is infuriating. It's obviously written by/for someone that already knows what they're doing. I'm not totally incompetent and I can't follow the web of documentation at all.

Alright, another day down the drain spinning my wheels. I looked at the traffic on my Ubuntu machine using wireshark and I don't think I'm getting any traffic from the board, which is weird because the PHY is up, and I can talk to it in u-boot, and it establishes a link.

I enabled the Marvel drivers in u-boot. The only thing I can think of is the "Enable Driver Model for Ethernet drivers" option in menuconfig. Again, I'm totally lost by where the support is for this.

With good setup I mean an officially supported TI EVM, running the SDK-provided SD card image.

If you can't get any valid IP address "on anything" (what else did you try to connect?), perhaps your DHCP server is not setup correctly?

There are instructions related to that here:

http://software-dl.ti.com/processor-sdk-linux/esd/docs/latest/linux/How_to_Guides/Host/How_to_Setup_Ubuntu_1404_Network_Boot.html

Basically, you'll need to run something like...

$ sudo apt install isc-dhcp-server

...and then update /etc/dhcp/dhcpd.conf as indicated in the aforementioned documentation.

I've tried that.

Can we take a step back and get back to my u-boot port. I'm not convinced I've enabled ethernet properly.

https://e2e.ti.com/support/processors/f/791/t/840520?66AK2H06-U-boot-cannot-initialize-88E1512-Ethernet-tranceiver-properly

This is a very similar PHY to what I'm using and seems like a similar problem. I don't know what's up with the dts in u-boot, per my previous comments. Do I need to update ethernet support to this new driver model, and create a dts and all that? I haven't created a dts for my board, and u-boot never seemed to care. I haven't seen anything about how to go about this.

So you confirm that you can get an IP address via DHCP using another "known good" board from your host machine? Important to know that side of the system is good.

Adam Gerken1 said:

Are you using the current TI Linux SDK v6.01, with its 2019.01-based U-Boot stream (http://www.ti.com/tool/PROCESSOR-SDK-AM335X)? If not please use this as this is the officially supported SW platform at the moment - it is also what the associated SDK documentation should be aligned with. Anyways this SDK already uses driver model for networking via CONFIG_DM_ETH=y assuming you build the .config for the AM335x EVM based on am335x_evm_defconfig. There are frequent changes related how to setup and configure things with the ongoing driver model migration throughout the history of U-Boot, and other things.

Using this default configuration I can see the PHY driver getting probed, and the phy-mode settings that I suggested earlier to experiment with from the DTS getting applied... See below extract from arch/arm/dts/am335x-bone-common.dtsi

&cpsw_emac0 {
        phy_id = <&davinci_mdio>, <0>;
        phy-mode = "mii";
};

You don't need to instrument your code like this, I'm just showing how DTS information is important to get Ethernet/PHY setup right with the current U-Boot. If you insist on using an older unsupported U-Boot you need to double-check/migrate the PHY mode settings accordingly which is where your issue could be.

Yes, If I plug something into the server it gets an IP address. I just don't see ethernet traffic from the AM3352 board.

I'll give that a try. I'm using 2019.04 from the eewiki site. The am335x_defconfig had to be very heavily modified because I don't have a lot of the things the evm does and it wouldn't compile and/or run.

Hi Adam,

How did you enable this? Via "make [...] menuconfig"? Looks like there are some unmet dependencies (CONFIG_DM_GPIO?). But working through those steps little by little can be challenging, especially if one has not much experience with U-Boot. Hence I'd like to re-iterate my earlier suggestion of starting with the U-Boot that is part of the current Linux SDK, which has CONFIG_DM_ETH (and also CONFIG_DM_MMC) already enabled, for a better starting point for experimentation.

If for some reason you must use the old U-Boot you are using please point me to the exact(!) U-Boot git tree you are using so I can have a look how to change PHY settings with that particular version of U-Boot.

Andreas,

I have CONFIG_DM_GPIO enabled as well.

It's not really that I must use this version, it's just what I've been using. It took me forever to even get something compiled so I'm not too keen on starting over with a different version. The SDK stuff is so dependent on hardware being the same as the EVM's with the EEPROM and all that I don't have, it was a pain getting all that out.

I used mainline v2019.04 with these patches: https://github.com/eewiki/u-boot-patches/raw/master/v2019.04/0001-am335x_evm-uEnv.txt-bootz-n-fixes.patch

Attached is my current config, with the extension changed so it uploads.

I just found this post which sounds extremely similar to the issue I'm having:

Hi Adam,

hmm, that patch you referenced disables CONFIG_DM_ETH...

-CONFIG_DM_ETH=y

Anyways looking at thew 2019.04 source tree, in case DM is not used for Ethernet setup, board/ti/am335x/board.c:board_eth_init() is the function we need to be looking at:

https://gitlab.denx.de/u-boot/u-boot/-/blob/v2019.04/board/ti/am335x/board.c#L965

The patch you pointed to actually also modifies/extends this function.

See where it sets any of the cpsw_slaves[ ].phy_if fields. Depending which of the code paths applies to your board, you can experiment with updating the respective section with different PHY modes, similar as I had suggested earlier to be done by modifying the DTS. Possible values to use are as follows:

a0797059@jiji:~/git/u-boot (HEAD detached at v2019.04)
$ git grep PHY_INTERFACE_MODE include/phy_interface.h
include/phy_interface.h:        PHY_INTERFACE_MODE_MII,
include/phy_interface.h:        PHY_INTERFACE_MODE_GMII,
include/phy_interface.h:        PHY_INTERFACE_MODE_SGMII,

include/phy_interface.h:        PHY_INTERFACE_MODE_RGMII_RXID,
include/phy_interface.h:        PHY_INTERFACE_MODE_RGMII_TXID,
include/phy_interface.h:        PHY_INTERFACE_MODE_RTBI,
include/phy_interface.h:        PHY_INTERFACE_MODE_XGMII,
include/phy_interface.h:        PHY_INTERFACE_MODE_XAUI,
include/phy_interface.h:        PHY_INTERFACE_MODE_RXAUI,
include/phy_interface.h:        PHY_INTERFACE_MODE_SFI,
include/phy_interface.h:        PHY_INTERFACE_MODE_INTERNAL,
include/phy_interface.h:        PHY_INTERFACE_MODE_25G_AUI,
include/phy_interface.h:        PHY_INTERFACE_MODE_XLAUI,
include/phy_interface.h:        PHY_INTERFACE_MODE_CAUI2,
include/phy_interface.h:        PHY_INTERFACE_MODE_CAUI4,

Not all of them apply obviously, but try those in analogy with the earlier suggestion.

Alright, I've been fighting this for a couple more days now. I've moved to mainline u-boot v2020.04 to use the driver model as in the SDK. I have to be close now and I just a have a couple questions that will hopefully keep me moving in the right direction:

I get in my u-boot boot log: "Net: error: phy_id read failed"

I think this may have something to do with the phy not working well. I've verified that my MDIO interface is working... once booted I can talk to the PHY. I also verified it's loading the correct Marvell drivers. I just can't figure out where that error message is coming from. any clues?

Another oddity is that if I don't do the pinmux in the board file the ethernet doesn't work at all, even though it's defined in my dts file as well. What's up with that? Do I really need both? Is something wrong with the setup of the dts? The dts definitely seems to be working, I can make changes and see the results when compiled and booted.

Lastly, and this isn't really an issue, but an annoyance, is there any way to get rid of the I2C lines? I don't have I2C, I have it disabled in the configs, etc. but the "Error, wrong i2c adapter 0 max 0 possible" error keeps showing up.

OK, got the phy_id error sorted. It was in CPSW.c if it failed to find phy-handle it would look for phy-id then fail that if it found neither, and since phy-id is no more, I was looking in the wrong spot. Apparently I was missing “slaves = <1>” in my dt. All good now. Ethernet still doesn’t seem to work though.

I have to see if I can figure out loopback on the PHY or something, at this point everything looks like it should be working but just… isn’t.

DTS is only used for pinmux on our platforms when CONFIG_PINCTRL_SINGLE and CONFIG_PINCTRL are active, which they are not for boards based on our current am335x_evm_defconfig. Please double-check the .config you use to build U-Boot with at the root of your U-Boot directory. Changes are those options are turned off, which explains and means that you will need to modify the pinmux in the board file (usually mux.c). Make sure that pinmux performed is overall representative of what you need for booting your system (boot & comm peripherals usually).

If you search where this gets printed you get here:

a0797059@jiji:~/git/u-boot (ti-u-boot-2020.01-am3-am4-evm-mini)
$ git grep -C 5 'I2C\:' common/

common/board_f.c-#else
common/board_f.c-       i2c_init(CONFIG_SYS_I2C_SPEED, CONFIG_SYS_I2C_SLAVE);
common/board_f.c-#endif

Which means is depending on CONFIG_SYS_I2C. Which itself for AM335x is defined here...

So since you have probably already disabled CONFIG_DM_I2C, you see how the above code then stubbornly enables non-DM support for I2C ;) Tracing back on how this file gets eventually included into your own custom board-specific header file in include/configs you see that this happens via #include <configs/ti_am335x_common.h>. So rather than modifying ti_armv7_common.h I would recommend trying to insert something like...

#undef CONFIG_I2C
#undef CONFIG_SYS_I2C

...into your own bord-specific include/configs/*.h file near the top (but past the include of ti_am335x.common.h). It can be quite confusing I think with the mix of Kconfig and headerfile-controlled CONFIG options in U-Boot but things are improving over time... Hopefully one day we can configure the entire U-Boot through Kconfig.

Have you tried experimenting with the phy-mode settings as suggest earlier?

If trying the different settings didn't help, what is the exact PHY P/N? And can you share the section of the schematic that shows the PHY and also how it is connected to the AM335x?

I tried the first two fix-ups. The I2C messages are gone, device tree pin control is still giving me a hard time though, I enabled those two CONFIGs and I still have to use the pin mux from board.c to have the MDIO return valid data on the PHY.

Yes, I've tried "rgmii" "rgmii-id" "rgmii-txid" and "rgmii-rxid" with the same results across the board... no packets sent.

The PHY is a Marvell 88E1510-A0-NNB2I000. Here are the two schematic blocks:

This is the AM3352 side:

This is the PHY side:

Pretty basic... I'm using the AM3352 internal pull ups on the MDIO and MDC lines. If you'd like the whole schematic I can send it via email.

Thank you for the help!

I'm going to try, both have vias, but the PHY is almost touching the SoC, the design is very compact. I guess this is why we don't order production quantities right off the bat!

Thanks again for the help, got a lot of other minor things smoothed out along the way, and I know u-boot way better than I did before, so that's something.

I am still curious about the dt pin muxing issue though, I'd like to push this towards the driver model as much as I possibly can and whittle down the board file dependence.

Here's the DT entry for the Ethernet stuff, anything jump out at you? Also, my latest config is attached.

Adam,

Adam Gerken1 said:
I enabled those two CONFIGs and I still have to use the pin mux from board.c to have the MDIO return valid data on the PHY.

Careful, sometimes it's not as easy as this. You need to make sure that there are no conflicts with board code that may still be getting called. Then, if you need pinmux done in SPL, the respective DTS nodes may need to get marked up with u-boot,dm-spl otherwise they'll get stripped out during SPL build and nothing will work. If you want to use DTS-based pinmux it'd probably be worth looking at an AM335x-based platform that already uses it (there are some in the U-Boot tree), and see how it is managed from a DTS and platform code perspective.

Regards, Andreas

Thanks again for the help, got a lot of other minor things smoothed out along the way, and I know u-boot way better than I did before, so that's something.

You definitely struggled through a good cross-section of potential issues and U-Boot quirks. Some of that stuff can be mitigated with better documentation (we are trying this), and some of it just requires some elbow grease to struggle through it in my opinion. Learning curve is a bit steep but yes it does get easier.

Adam Gerken1 said:
I am still curious about the dt pin muxing issue though, I'd like to push this towards the driver model as much as I possibly can and whittle down the board file dependence.

See my other comment. Probably want to pick an existing board with DT-based pinmux config and model from there.

OK, new hardware is in and it's looking much more promising now! I actually get traffic on the ETH interface but now I'm back to square one and still confused exactly how to move forward.

I'm now thinking I'd like to do the whole boot process through TFTP instead of serially loading the MLO an u-boot. When I try and boot from ETH I see the BOOTP requests in my ubuntu machine:

So now I guess I have a couple new questions:

Where do I go from here? Is there an official TI walk through. I've tried: https://processors.wiki.ti.com/index.php/Ubuntu_12.04_Set_Up_to_Network_Boot_an_AM335x_Based_Platform that I got from:

None of those configs seem to do anything. I tried changing the vendor-class-substrings to the "TexasIns" I see with no luck. Any ideas?

Since I've had the most luck with mainline u-boot, and have images from before that I think are solid, I'd like to just use those. Is there anything in particular I need to to do to enable network boot other than enabling network support in the MLO and u-boot, and leave in the networking env variables?

Lastly, I still can't get the MDIO/MII pinmux working strictly via the DM, even when copying an evm config but that's super nitpicky at this point, I just want to get this thing booted and move on.

Edit: definitely looks ubuntu side. If I plug the board into my regular network, load MLO and u-boot through the serial and do "dhcp" I get a valid address.

Thanks,

Adam

Great but what's different with the new HW? Did you root cause why now basic Ethernet connectivity seems to work?

This page is outdated and causes more confusion at this point than it is good (it will get removed by e/o 2020). The current recommended steps are documented as part of the TI Linux Processor SDK documentation available at http://software-dl.ti.com/processor-sdk-linux/esd/docs/latest/linux/How_to_Guides/Host/How_to_Setup_Ubuntu_1404_Network_Boot.html

While those steps say Ubuntu 14.04 I had no real issues doing that setup on a Ubuntu 18.04 machine.

It should "just work", no changes to U-Boot or config needed to enable Ethernet boot. At least that's the case with the TI SDK provided U-Boot tree. But upstream U-Boot and TI U-Boot for AM335x are very close as AM335x has been around for a while, so upstream support is quite mature.

The TI reference platforms use platform/board data to initialize the Ethernet pinmux, I'd try to stick to that. If you want to use DTS you will need to debug this some more to see as to what exactly is failing. It could be as simple as missing "u-boot,dm-spl;" nodes in the device tree which would lead to certain parts of the DTS getting optimized out during the SPL build, and the probe to partially fail. Or it could be something else. You could use printf() style debugging or a JTAG debugger to verify actual pinmux control register settings at various stages, comparing DTS-based Ethernet pinmux initialization vs. board-data based pinmux initialization - this should tell you exactly what is missing.

Edit: definitely looks ubuntu side. If I plug the board into my regular network, load MLO and u-boot through the serial and do "dhcp" I get a valid address.

That's perfect, but then again, what's different now?

I had the RGMII TCTL and TCLK signals mixed up between the AM3352 and PHY. reworking them wasn't possible so I had to have new boards made.

I'll check out that page for getting network boot up and running.

Thanks!

Andreas, Getting close now, I can taste it. I've got my DCHP/TFTP server set up per the instructions. It took a little monkeying around. There's a typo in the example config that took me longer than I'd like to admit to find:

elsif substring (option vendor-class-identifier, 0, 10) = "AM43xx U-B"
   {
      filename "u-boot-restore.img";
   {

There's two open brackets there.

Anyway, I've now got it up and running and getting an IP address and everything but I'm getting an ICMP error and no file transfers. Any ideas? I've made sure there are no firewalls in the way, tried a switch between the board and PC, rechecked my set ups, etc.

Hi Adam,

Sounds like you may not have a TFTP server setup?

You need TFTP setup to serve "u-boot-spl.bin". This is in addition to the DHCP server. See point 5 of the setup instructions at software-dl.ti.com/.../How_to_Setup_Ubuntu_1404_Network_Boot.html

Ah, so close. I still had the TFTP server from that old page installed. I didn't catch that they were different packages. Uninstalled that, and it took right off.

Now it looks like it loads the spl but then everything goes quiet, doesn't try to loadu-boot and there's no serial output... more digging to do apparently.

Thanks,

Adam

Can you share a log of that?

Also what does Wireshark say? Do you see the board requesting U-Boot?

Sounds like SPL is not being able to use the Ethernet interface to continue loading probably because of some configuration issue. The good thing is using the ROM-based bootloader Ethernet essentially is proven-good. So at this point it should just be a U-Boot configuration/setup issue.

Here's the end of the TFTP transfer. THe ERRORs are erroneous, I found another post about it. There are no actual packet errors recorded if I do an "ipconfig."

After this the board disappears, nothing from 192.168.2.2, no request for u-boot, nada. I agree it's most likely an spl configuration issue, I just have to back and double check everything.

If I may make a suggestion I would probably recommend going back to how networking is setup on one of the existing platforms from a DTS, CONFIG_*, and platform data POV as a known good starting point. I think you may have since made various changes in an effort trying to get various things working, but what may be needed now is to just go back to a known-good starting point as used on an existing platform. It should not be too hard to get this over the hump with what you already have working now.

Finally getting back into this project... I found some SPL configs that weren't enable to allow Ethernet and such. I think I got that sorted out but now the spl just requests u-boot-spl over and over instead of moving onto the u-boot image. Still no serial out.

I'm going to try loading this spl through uart and seeing what happens. Maybe it's resetting or something.

EDIT: yeah, SPL is now just causing a reboot after it loads.

EDIT 2: The older imagines I made based on the eewiki patches loads the SPL and gives me an "Unsupported Boot Device" error at least the board is alive and I just have to find the right combo of booting magic.

Sounds like (and you had mentioned that earlier) that you have no serial output at all. The issue with serial port bringup in SPL is that it happens very late into the SPL startup, past failure-prone things like board detection logic (if still there) and DDR bringup. Can you enable the early debug UART as per instructions here (scroll down to "Setup early (debug) UART"): software-dl.ti.com/.../U-Boot.html

This might give you some additional clues. And enable you to add printf() statements to trace program execution to help narrow down where it is failing.

Regards, Andreas
