USB Host on port 2 AM5728 custom board

Dexter Travis
Intellectual 350 points

Other Parts Discussed in Thread: AM5728, TPS659037

We are in the process of board bring up on a custom board using the am5728.  We based our hardware design heavily on the Beagleboard x15 with schematic review by TI. We intend to act as host only on both USB1 (3.0 on board only) and USB2 (2.0 type A connector)

I am working on a kernel branch on our local git repo. About once a week I merge in from ti-linux-4.4.y on git.ti.com to my local branch. 


Prior to the latest merge our board could get functional USB working only about 1 of every 10 power cycles.  The other 9 times I would get a kernel crash. The crash was in xhci_hub_control.  When USB was disabled in devicetree it never crashed in this way. This crash always occurred just after it detected the root hub for USB2.


Now as of the latest merge (last monday 28 march) which included several of changes to the dwc3-omap driver recently merged from connectivity branch to the ti-linux-4.4.y branch I now get a kernel crash on every boot in the dwc3_omap_interrupt function of drivers/usb/dwc3/dwc3-omap.c


I get the crash even when all usb are status="disabled" in my device tree.  In order to avoid the crash I must not enable the DWC3 USB drivers in the kernel.


Attached is my defconfig file and our device tree files.


Any help would be greatly appreciated.

    Dexter, Did you see this same behavior on the 4.1 kernel? TI isn't intending to support the 4.4 kernel until ~July.

    The 4.4 branch you're using is under development and not yet officially supported. Also, your defconfig is substantially different than the omap2plus_defconfig that TI uses for testing/development.

    A few suggestions:

    1. Try using the omap2plus_defconfig. It could be that there's a dependency somewhere not captured in Kconfig. If that's the case, this test would give you a good starting point.

    2. Try reproducing this same issue on the official 4.1 kernel.

    3. Try reproducing the issue on the AM5728 EVM (with your own kernel).

    1) omap2plus_defconfig has LOTS of stuff built as modules.  I ran a kernel with it unchanged. Yes it booted but it never loaded the dwc3 module and so never encountered the bits of code that cause the crash.  I next went in through menuconfig and made all usb host stuff built in not a module.  I get the following build time error.  I think this implies a possible missed dependency in kconfig ?  I was able to config the kernel to have extcon as a module and dwc3 as built in.

make: *** [vmlinux] Error 1

    Once I config extcon as builtin these build  errors went away.  They are not holding me up but may confirm that kconfig deps are not all worked out.

    After building with omap2plus_defconfig modified to use built in not module i do not ever see the dwc3 driver load at all.  USB core and platform drivers do load dwc3 drivers do not thus omap2plus_defconfig work to this point is not conclusive.   Below are my dmesg entries for USB with a modified (built in not modules) omap2plus_defconfig. At this point also lsusb returns -99 unable to initialize usb.  I have re-enabled usb2 and usb1 in my devicetree.

    2)  I will work again on the 4.1 in the next few days to see where I get.  I have been on and off of it several times in the last few weeks, generally i have gotten further with 4.4 but will put in more effort on 4.1.  Regardless, we plan to ship with 4.4, the sooner we can get running and working on this the better.  Is it typical for TI "mainline linux" support to be 7 months or more behind mainline linux?

    3) The AM5728 EVM has proven to be of mixed value.  In the case of USB it only supports USB gadget mode on USB2 which we will be host mode.  This makes it very difficult to do apples to apples work on USB with my board vs the EVM.  For other peripherals it was/is useful.

    I have reproduced the usb issue on linux 4.1 on my custom board.  The procedure to recreate it was as follows.

    Started with ti-linux-4.1.y commit 9669eef768ece4c18cf5e555a89658f9159ee4a5.

    copied am57xx-beagle-x15.dts to my pp-ssmg3.dts file and modify it to match my board. Also added this to the dts makefile.

    copied tisdk_am57xx-evm_defconfig from the tisdk release 2.0.1.07 to my arch/arm/configs directory.

    built the kernel using the unmodified tisdk_am57xx-evm_defconfig. 

    built and installed modules onto my sd card which i boot from.

    Booted with my dtb file.

    Attached are the boot log files from the serial terminal and my dts file.

    Dexter,

    I am not in the part of the schematic review process. Can you please post the usb portion of the schematics? I'd like to see your change to the usb2 port.

    Bin,

    Attached is USB portion of the schematic.  Note that I am currently concerned with USB2.  USB1 (configured as a 3.0 host) will not come online until our next board revision. 

    I have also tried a couple of other things that may be of value. 

    1) I moved to u-boot from the ti-sdk 2.0.1.07 only changed the dmm_lisa_regs value to match our RAM configuration.  I did this because some online reports by Robert Nelson implied that some version of u-boot would "break" USB for the kernel.  My test results are identical with u-boot from ti-sdk and u-boot from tag 2015.07 from git.ti.com/ti-u-boot.git

    2) I modified the device tree to remove the palmas extcon usb, as this more closely matches our schematic.  Results are the same with the dts i previously posted and the one posted here now.

    Finally, we are doing a small board revision for unrelated issues.  If we need to change the USB schematic it would be very important to have that finalized by early next week.

    Dexter,


    I am unable to tell what exactly wrong, but it seems your system has something disabled which causes the access abort. I see your dts is quite different from am57xx-beagle-x15.dts, so it might be a problem in the dts you modified.

    BTY, I took the TI 4.1.y kernel and only changed usb2 dr_mode to host in dts, then I am able to run host mode on usb2 port of X15 Beagle board. Of cause, I have to add external power to vbus line.

    I was hoping for a bit more direction in terms of what might be wrong in the device tree.

    Attached is a new device tree file that recreates the issue with a minimal number of changes to the device tree relative to the beagle x15.  My changes were as follows...

    1) disable hdmi.  My board does not have any hdmi.

    2) remove references to sound, i don't have sound and leaving it in the device tree causes unrelated crashes trying to probe mcasp3.  

    3) change usb2 dr_mode to host.

    I still get the same crash.

    Given my schematic, host only with no id connection and usb2_drvbus connecting directly to the switch without feedback through the PMIC can you help figure out what the devicetree should be?

    Thank you

    Dexter

    BTY, I took the TI 4.1.y kernel and only changed usb2 dr_mode to host in dts, then I am able to run host mode on usb2 port of X15 Beagle board. Of cause, I have to add external power to vbus line.

    It occurred to me this morning that your test is not sufficient to show proper operation.  As I understand it, in host mode the AM5728 uses the usb2_drvvbus pin to enable and disable vbus to the port through an external switch or power supply.  You have bypassed this function by supplying vbus manually. 

    I await TI response regarding how if possible I can get my circuit to work by modifying either the driver or devicetree. If that is not possible please advise how to modify the circuit for host function.

    Do any of your other EVMs have examples that were designed from the beginning for host mode on this port?  Will you please share schematic and devicetree information for these boards?

    As I understand it, in host mode the AM5728 uses the usb2_drvvbus pin to enable and disable vbus to the port through an external switch or power supply. 

    Yes, that is the intent of the usb2_drvvbus when using USB2 as a host.  I see your design has connected this to a power IC as expected.

    Do you ever see your IC being turned on and providing the necessary 5V?  I suspect that since the EVM was not using this pin, that it was not ever being configured.  Along those lines, it would be useful to see the value of the register CTRL_CORE_PAD_USB2_DRVVBUS (address 0x4A003684).  You could potentially grab this with JTAG or if you can disable USB to actually get your board booted you could do "devmem2 0x4A003684".

    Dexter Travis said:
    You have bypassed this function by supplying vbus manually. 

    We don't have an IC on our EVM to produce 5V.  USB2 was intended to be a device where the 5V was an input which we detect.

    Dexter Travis said:
    Do any of your other EVMs have examples that were designed from the beginning for host mode on this port?  Will you please share schematic and devicetree information for these boards?

    I had a look at our automotive EVM, but unfortunately it's nearly equivalent in that USB2 was designed as a device port.

    I was also looking at this part of your dts:

    extcon_usb2: tps659038_usb {
    compatible = "ti,palmas-usb-vid";
    ti,enable-vbus-detection;
    interrupts-extended = <&gpio4 21 IRQ_TYPE_EDGE_RISING>;
    };

    That portion of code is for configuring the TPS65903x to detect the 5V (i.e. from having been "plugged in" to a host). Are you using this feature? Perhaps for USB1? It may need to be adjusted or removed depending on your setup.

    Regarding the extcon_usb2 in the device tree,  I have tried it with and without. I have also tried doing an extcon_usb2 in the same fashion as extcon_usb1, outside of palmas.  In that case an ID pin was required and I configured it to an unused pin. I tried both internal pull up and pull downs on that ID pin. It seems to make no difference.  Frankly I have tried every combination and permutation I can think of that even remotely makes sense.

    The latest device tree in this thread was my attempt at being as close as possible to the x15 since Bin thought i was significantly different.

    The most success I had was with the TI 4.4 kernel prior to the connectivity branch merger on the TI side.  Roger Quadros I believe did most of the USB commits in the connectivity branch. In that kernel I was able get USB 2 fully functional in about 1 of 20 power cycles.  The other 19 power cycles i got the xhci_hub_control crash.  In the 1 of 20 attempts when it did work, usb2_drvvbus was correctly controlling the power switch IC and 5v was on the line.  Therefore we have proven the circuit works and eliminated board specific issues.

    I see that usb2_drvvbus line is available on the expansion connectors of the x15.  There is even a note in the device tree for the x15 about the ability to do host mode on the expansion headers.  Is it possible for someone on TI side to do this with the current 4.1 or 4.4 branch and verify function?  I have done my best to mimic as much of your software with as little modification as possible and I still see the issue.  I would appreciate if TI came at this from the other side and tried to mimic my hardware as close as possible.

    Is the 5V supply being enabled when you are running with the 4.1 kernel?  Please use a multimeter to verify.

    This sounds like what Bin already did with the exception of using usb2_drvvbus, though you sound pretty convinced that you already have usb2_drvvbus functioning properly.  I think it would make more sense for you to try and replicate Bin's result using the TI EVM.

    "This sounds like what Bin already did with the exception of using usb2_drvvbus," 

    Yes, that was exactly my point.  Him not using vbus is a critical difference.

    I tried to reply via email and don't see that post coming through the following is from the email, so it may appear twice if the email ever comes through.

    Currently in the 4.1 kernel with a couple of different device tree configurations including the one I used back when it worked sporadically the usb2_drvvbus pin is NOT activating.

    I tried applying 5V directly to the USB port on my board.  I get the same crash from the kernel.

    As a reminder since we keep getting new people on this thread, I was able to sporadically get USB fully functional prior to recent merges.

    The image below is what I see immediately after power on.  I think this is a power on glitch followed by u-boot turning on vbus.  All that is in this image occurs before the kernel starts to load.  After this point the line is always low.

    Yellow is the vbus control line, blue is vbus itself.

    It appears you have a typo in the usb2_pins.  the pin address for usb2_drvvbus is 0x284 not 0x2c4.  You appear to have copied from the usb0_drvvbus.

    I will give this a try this afternoon and report back.

    Sorry about that. Good catch!  I've gone back and cleaned up my original patch.

    Intellectual 350 points
    I started with the 4.1 kernel we had been working on. This was my attempt at making it as close as possible to the TI 4.1 kernel and x15 device tree. I then made the device tree changes Brad suggested.

    I now see that sometimes when i power cycle the usb2_drvvbus line does come high. When the line does come high, then USB does work. When the line does not go high USB does not work. It appears much more likely that when I apply 5v externally to USB on the USB side of the vbus control switch that it comes up correctly. I observe that when I supply 5v to the VBUS from a bench supply it feeds back through the switch and powers other systems.

    I have also observed the 3.3V USB and 1.8v PHY USB line that comes into the Am5728. When the system works 3v3 USB is at 3.3volts. When the system fails 3.3v USB is at or near ground. Some state machine somewhere is not always turning on 3v3 output from the PMIC to my USB 3v3 input. Somehow applying the 5V is sticking something so that this line does come on. The 1.8 line appears to always come up and be correct.

    Any suggestion on how to make sure that always happens would be appreciated.

    I should note that I am using ES1.1 silicon.

    Great! I think we're closing in on the issue now...

    Are you using the TPS659037 as your PMIC? What does VUSB_3V3 from your schematic connect to on the PMIC? Does it connect to LDOUSB_OUT (like the EVM)?
  • 0 in reply to Brad Griffis
    Intellectual 350 points
    Yes, TPS659037 PMIC. LDOUSB_OUT of the PMIC goes directly to VDDA33V_USB1 and VDDA33V_USB2. There are several capacitors on the line a 10uF, 2.2uF, 0.1uF and 1000pF.

    And what is the supply rail for the LDOUSB_IN pins of the PMIC?
  • 0 in reply to Brad Griffis
    Intellectual 350 points
    The input to the LDOUSB_IN of the PMIC is the main 5V bus that runs lots of stuff on the system. Its turned on by an external MCU. It is on before the PMIC or the AM5728 are out of reset or powered up. The LDO12_IN on the PMIC is fed by the same 5v line as LDOUSB_IN.
  • 0 in reply to Dexter Travis
    Intellectual 350 points
    That main 5V line which is the LDOUSB_IN and LDO12_IN connection is also the 5V line that I backfeed when I hook up vbus to an external 5V supply. Generally 12V DC comes is and is stepped down to 5V by an on board regulator (not the PMIC) to supply this.

    I also tried to add palmas_i2c_write_u8 commands to the late_init function on u-boot in order to poke the PMIC registers that I think control the LDOUSB. in particular 0x164, 0x165 and 0x16A. I do not see the VDDA33V_USB lines go high like I expect when I write to the those register to enable the output.

    TI__Guru*** 125430 points
    Which I2C bus of the AM5728 is connected to the PMIC? Have you probed the bus near the PMIC to see if there is proper communication? In particular if there's any level translation, etc. it is easy for something to get messed up there.
  • 0 in reply to Brad Griffis
    TI__Guru*** 125430 points
    One other thought that comes to mind is whether LDOUSB is outputting the appropriate 3.3V as part of the power-up sequence. I expect that it should be high before the AM5728 is even released from reset. However, if it's not for some reason that would explain the behavior. And if that's the case, we'll definitely need to pull in the PMIC team to assist.
  • 0 in reply to Brad Griffis
    Intellectual 350 points

    PMIC is connected directly between the 5728 and the PMIC.  It is on I2C1 of the AM5728.  I believe this is the same as the EVM. It has 2.2k pullups to 3.3v_sw2.  That power is up as soon as 12v is applied to the overall system input.

    Yes there is I2C activity on that line.  I did confirm with a logic analyzer that the commands I added are present and the logic analyzer reads them correctly and the PMIC acks them.

    The 5728 is held in reset for about 1 second after 5v is enabled to the PMIC.  That seems like it should be tons of time for the PMIC to have vdd33v_usb up.  Also even when i issue commands through u-boot to turn on the 33v_usb it does not happen.

    We stumbled into a test case that may shed some light to the PMIC team. We hold the AM5728 in reset forever. so nothing ever talks I2C to the PMIC.

    In this scenario I can apply power and get both results. VDD33V_USB low at ground and VDD33V_USB coming up. However when it comes up VDD33V_USB only comes up to about 2.16 volts. Not all the way to 3.3v.
  • 0 in reply to Dexter Travis
    TI__Guru*** 125430 points
    Thanks for this info. That's a great test case. This rail should be coming up to 3.3V without any software intervention whatsoever. It's part of the power-up sequence. So you're saying when you hold the AM5728 in reset and examine the power-up sequence you get inconsistent results? sometimes it stays at 0V and other times it comes up to 2.16V?

    Can you tell me the precise orderable part number that's placed on your board? I need to talk this over some more with the PMIC team. There are a lot of variations of this device, so I need the complete part number please.

    TI__Guru*** 125430 points
    The PMIC team was wondering if there might be an issue somewhere that a 3.3V rail is somehow coupled to a 1.8V rail. The 2.16V that you sometimes see looks suspiciously like 1.8V + a diode to clamp the voltage. Can you look through more of the voltage rails in your design to see if perhaps there's another one that looks suspicious? Another suggestion mentioned was to remove the processor altogether from your board to see if that "fixes" the PMIC. That could help us narrow this down quite a bit in terms of where we go hunt.
  • 0 in reply to Brad Griffis

    I don't have the capabilities here to remove the AM5728. That would require sending it back to our CM and would take at least a week round trip. Lets avoid that if we can.

    Interestingly the other 3.3V rails that come out of the PMIC are also at 2.16 as you suggest. The input rails to the PMIC are at 3.3v.

    LDO1_OUT, LDO2_OUT and LDOUSB_OUT are all at the same 2.16 volts.

    Will you please have another look at LDOUSB_IN?  All of these data points above are consistent with having insufficient input voltage on this net (LDUSB_IN and LD12_IN).  The other place where we might look is the output of LDO1 and LDO2.  I recommend revisiting the input once more first though.

    I was able to capture a scope trace of the 3.3v USB output of the PMIC during a "working" boot.  

    I am able to twiddle the power connection such that by watching the scope and quickly connect/disconnect power at a boot I can get it to "work" the line goes all the way to 3.3v.  During initial boot up it goes to an intermediate voltage for a little while.

    If I just apply power from a cold state and do not twiddle the power connector I see zero activity on the VDDUSB line (flat line).

    Attached is the twiddled power working case.

    Can you get a scope shot of LDOUSB_IN relative to LDOUSB_OUT during the ramp up? It might also be useful to see the PMIC's RESET_OUT signal. I was trying to correlate some of the activity on LDOUSB with other events, and I think releasing the processor from reset is probably a decent guess.

    If possible, please provide a screenshot for a bad case (0V) as well as the "eventually successful" case.

    FAILING CASE 1

    pink is pmic reset out.

    yellow 3.3v going into the PMIC for the other LDOs.

    light blue is the LDOUSB_IN line between D9 and the PMIC

    dark blue is USB3v3_OUT

    Failing Case 2

    All lines same as case 1 except yellow.  Yellow is now 5V before D9.  Schematically Yellow feeds through D9 to light blue.

    Based on these observations it appears the PMIC is allowing voltage to bleed through internally from the 3.3v LDO inputs to the LDOUSB input.  

    The LDOUSB_IN is only connected to D9 and the PMIC and some caps.  D9 selected between mains power and battery power.  The battery is not installed and at the time this net goes high (to 2.16 volts) there is no voltage on either 5V or the battery line. (I also took scope shots of the battery line not shown).  It seems that first hump in light blue must be coming from a back feed from the PMIC internally.

    Working Case 1


    dark blue is USB_OUT 3v3.  

    Pink is PMIC_RESET_OUT

    light blue is LDOUSB_IN between D9 and the PMIC.

    yellow if 5V feeding into D9.

    Currently we have the MCU (a non ti 32 bit device) controlling 5v regulator enable line.  I am going to bypass that so that 5V comes up at the same time as 3v3 so all the LDO inputs get voltage at the same time.  I will let you know results.  

    I look forward to hearing the opinions of the PMIC team.

    TI__Guru*** 125430 points
    If LDOUSB is enabled prior to having a stable input supply, this wall cause the LDO to register a short-circuit which will keep it off. I think that's the issue here. It looks to me like the PMIC is at the very end of the sequencing (i.e. RESET_OUT going high) before it even has a stable 5V supply. I think you need some additional sequencing to properly time when the PMIC starts to ramp.

    When you're referring to "D9" are you referring to pin D9 (VIO_IN) of the PMIC, or is that a component on your board?
  • 0 in reply to Dexter Travis

    I modified the board so that 5V and 3.3V come up roughly at the same time and took the external MCU out of the circuit (it was delaying 5v enable).

    So far the results look very promising.  I am about 5 out of 5 good resets from a cold state.

    yellow = 3.3v  (ldo inputs to other ldos on pmic)

    light blue 5v (ldousb pmic input.)

    pink (pmic_reset_out)

    How are you initiating the PMIC power sequencing? Is there a push button somewhere, or is there some circuitry in there to make it power-up as soon as power is present? Based on the oscilloscope captures, it looks like a small change should be made such that the PGOOD from the 5V rail should be used to start up the PMIC. For example, if you keep PWRON pulled high and then connect the 5V PGOOD to POWERHOLD, that should do it.
  • 0 in reply to Brad Griffis

    a 12 VDC line goes high and the system turns on This should start the whole process.  We have a key switch input to turn on/off with the key position (think automotive).  At the moment key is tied to 12V in and both come up together.  This is a scenario we need to support.

    It looks like the POWERHOLD input is limited to VIO voltage range and cannot take the full 5v from 5v power good.  Fortunately 5V power good is open drain.  I pulled it up to the same 3.3 line that powers VIO.  It looks like VIO comes up a bit after 5V so the PG line is not as sharp an input as I would like.  However, it works.

    It appears this also gets rid of the PMIC_RESET_OUT pulse that was happening a little while after power up.

    Attached are some scope captures.

    This is the zoomed in version of power up, showing the PG coming up with 3.3 VIO.

    Yellow 3.3V VIO input to the PMIC also the line that 5v PG is pulled up to. 10k pullup.

    light blue 5V

    pink 5v PG output going into the powerhold pin of the PMIC

    dark blue VUSB LDO output.

    Same as above zoomed out except Yellow is main 3.3v not 3.3v VIO.  This yellow is the 3.3v that triggers 5v to start up.

    Questions:

    1) Is it OK to pull up to VIO like this given that VIO is coming up after the other voltages?

    2) Is it better to tie VIO and the POWERHOLD pull up to the primary 3.3v so that all come up together?

    3) Now that PG out controls POWERHOLD can we go back to having the MCU control 5V independently of main 3.3v and thus have those two input voltages to the PMIC not coming up together?  Or does all the LDO inputs need to be coming up together?

    We would prefer to pull POWERHOLD up to the 5V line. Please verify my understanding that this input is in the 5v tolerant space and that this is safe to do for the PMIC.

    That was my conclusion as well in terms of being the simplest. I'm confirming with the product group to be sure.

    I'm a little confused that the PMIC turned on at all when you pulled PGOOD to VIO. Isn't VIO enabled by REGEN1?
  • 0 in reply to Brad Griffis
    Intellectual 350 points
    We have VIO pulled up to a switched version of the 3.3V input that powers the LDO inputs. It is independent (at least on our system) of the PMIC outputs.
  • 0 in reply to Brad Griffis
    TI__Guru*** 125430 points
    The product group has confirmed that 5V DC is fine on the POWERHOLD pin. So puling it up to 5V sounds like the best solution.

    Before we close this out, I think it would be good if you could confirm that leaving PWRON pulled high and POWERHOLD driven low (e.g. don't pull it to anything) keeps the PMIC "off" (i.e. none of the rails turn on). Additionally (or maybe alternatively), it would be good to grab a scope shot of the 5V PGOOD relative to SMPS8. The first rail to turn on is SMPS8, so if we can show that it waits until after the 5V PGOOD transitions, then I think that proves you have everything wired properly.

    Also, just to be clear, is the USB2 Host working all the time now? Or is there still a software issue tied into this?

    I think the primary issue here was that we needed to fix the sequencing such that the PMIC turns on *after* the 5V rail is stable. The smaller issue was fixing the usb2_drvvbus signal in the dts. Correct?
