AM4376: Kernel boot fails on custom board

Rob Peipert

Part Number: AM4376
Other Parts Discussed in Thread: TPS62362, AM4372, AM4379, TPS62360

We have a target board with multiple AM4376 SOCs and I am trying to get zImage to boot on at least one of the SOCs using u-boot. The following observations and debugging steps have been performed and the result is described below.

1) I am using an AM437x IDK EVM as the base for my target u0boot and zImage.

u-boot is built, with modifications for the target, using board-support release version ===> u-boot-2018.01+gitAUTOINC+313dcd69c2-g313dcd69c2

zImage is built, using the default configuration for the AM437x, tisdk_am437x-evm_defconfig, using board-support release version =====> linux-4.14.79+gitAUTOINC+bde58ab01e-gbde58ab01e

The only modification to the zImage is to add debug print statements in main.c and setup.c (suggestions from other E2E and open source forums)

main.c/ start_kernel function looks like this:

asmlinkage __visible void __init start_kernel(void)
{
char *command_line;
char *after_dashes;

pr_info("start_kernel() 00\n");

set_task_stack_end_magic(&init_task);

pr_info("start_kernel() 01\n");

smp_setup_processor_id();

pr_info("start_kernel() 02\n");

debug_objects_early_init();

pr_info("start_kernel() 03\n");

cgroup_init_early();

pr_info("start_kernel() 04\n");

local_irq_disable();
early_boot_irqs_disabled = true;

/*
* Interrupts are still disabled. Do necessary setups, then
* enable them.
*/
boot_cpu_init();
page_address_init();
pr_notice("%s", linux_banner);
setup_arch(&command_line);

...

and setup.c / smp_setup_processor_id() looks like this:

void __init smp_setup_processor_id(void)
{
int i;
u32 mpidr = is_smp() ? read_cpuid_mpidr() & MPIDR_HWID_BITMASK : 0;
u32 cpu = MPIDR_AFFINITY_LEVEL(mpidr, 0);

pr_info("smp_setup_processor_id Start\n");

cpu_logical_map(0) = cpu;
for (i = 1; i < nr_cpu_ids; ++i)
cpu_logical_map(i) = i == cpu ? 0 : i;

/*sm
* clear __my_cpu_offset on boot CPU to avoid hang caused by
* using percpu variable early, for example, lockdep will
* access percpu variable inside lock_release
*/
set_my_cpu_offset(0);

pr_info("Booting Linux on physical CPU 0x%x\n", mpidr);

}

2) Booting zImage on the AM437x_IDK_EVM board boots as expected and outputs the debug messages as expected, here is the console output of the startups from u-boot.

Starting kernel ... <============= Last message printed by U-boot
<============= Target board does not get to start_kernel()?????

I think our target is having issue at a much lower point in the boot process than main.c, perhaps in Init.S or at the _start vector? I do have an XDS560 emulator connected to the target using CCS, when I am connected to the CortexA9 and pause debugging I stop in the address range 0xC01023C0, but I have not been able to load symbols for zImage to see what function/tag this is in the source? Perhaps, help with loading symbols may reveal more details?

Also, it is not clear what could be different from the EVM to the our Target? The EVM uses an AM4379 while our target is AM4376. The devicetree for the am437x-idk-evem is referencing targets in the AM437x and AM4372 family so I am not sure is need to make an update there?

Any direction you can give in debugging this boot issue is most welcome, I continue to look for samples on what to debug before Linux enters main.c and have not found anything yet.

Thanks in advance,

Rob

Rob,

When we see things fail at Starting Kernel it is usually related to DT. Can you try to disable some of your less critical interfaces in your DT and see if you can get different results? We usually recommend starting with kind of a bare DT and adding things in iteratively.

Hopefully this is helpful to you.

I removed devices form the DT until it looked like this:

/dts-v1/;

#include "am4372.dtsi"
#include <dt-bindings/pinctrl/am43xx.h>
#include <dt-bindings/pwm/pwm.h>
#include <dt-bindings/gpio/gpio.h>
#include <dt-bindings/input/input.h>

/ {
model = "TI AM437x Industrial Development Kit";
compatible = "ti,am437x-idk-evm","ti,am4372","ti,am43";

chosen {
stdout-path = &uart0;
};

aliases {
};
};

Our target still does not boot?

Are there additional devices in the AM4372.dtsi that may be at issue? Or have I removed too much from the am437x-idk-evm.dts file?

Regards,
Rob

In trying to debug this issue further I found this link:

http://processors.wiki.ti.com/index.php/Kernel_-_Common_Problems_Booting_Linux#Problem_.231_-_No_more_output_is_seen_on_the_console_after_.22Starting_Kernel....22

I updated the .config to turn on "Kernel hacking" and now I get this message when I run on my target.

It appears that the kernel is actually running on the target and uncompressing zImage successfully. The link indicates that there are 2 possible sources of error at this point:

1) Cause #2 B - Mis-match between device tree blob and the actual hardware

I have spent quite a bit of time debugging the devicetree and have found the root cause.

2) Cause #2 A - Mis-match between boot-loader and kernel machine numbers

Is it possible that the AM4379 used on the am437x-idk-evm and the AM4376 have different machine IDs? Do I need to rebuild zImage for the correct ID?

Thanks in advance,

Rob

Rob,

Is the above output using your full DTS or the abbreviated one? If abbreviated, I don't believe you have the necessary information to setup your console output.

Also, I wanted to clarify:

Rob Peipert said:

Is this correct, that you've resolved the issue?

Thanks.

0 Rob Peipert over 6 years ago in reply to RonB

Intellectual 550 points

That is a TYPO, my mistake. I have NOT found root cause or resolved this issue. Thanks for clarifying.

I have verified that using the abbreviated DTS does allow the console to work after Linux boots on the am437x-idk-evm, but not on our target board. I understand, that the device definitions for the uart's are in am4372.dtsi, which I have not modified and is included in the DTS I am using, this may be how the console is working?

Yesterday, I performed addition trace using the console of the zImage boot through head.S code in arch/arm/boot/compressed/ but without symbols it is difficult to determine what label is the entry point to the kernel at the label __enter_kernel. It appears that r4 of processor contains the entry point and it intialized by the "zreladdr" MACRO in Makefile.boot?

Regards,

Rob

Rob,

Does your board have an RTC crystal?

If the RTC crystal is not in the board design that is in the TI EVM design, in this function in arch/arm/mach-omap2/omap_hwmod_43xx_data.c please try commenting out the marked lines and see if the boot proceeds.

int __init am43xx_hwmod_init(void)
{
int ret;

omap_hwmod_am43xx_reg();
omap_hwmod_init();
ret = omap_hwmod_register_links(am43xx_hwmod_ocp_ifs);

-> if (!ret && of_machine_is_compatible("ti,am4372"))
-> ret = omap_hwmod_register_links(am43xx_rtc_hwmod_ocp_ifs);

return ret;
}

0 Rob Peipert over 6 years ago in reply to RonB

Yes our board has an RTC crystal and it is different than the one on the TI EVM board.

I edited the file as you suggested and it appears that out target board is booting.

Is it possible that these changes have any effect on other Linux functionality?

At present, my target is getting an IP address from the bootp server but it cannot mount the rootfs on the nfs server? (keep in mind the bootp and nfs server I am using is the same one that the am437x-idk-evm board connects without issue.).

Here is printout of what I am seeing:

After speaking with our hardware design team I have an additional data point on this issue.

My assumption was that our target had a crystal connected to the internal RTC of the AM4376, but that it was a different crystal than the one used on the am437x-idk-evm. This is not correct. In fact, our target uses an external RTC connected via I2C that has a crystal driving it and NO crystal connected to the AM4376 internal RTC. ( My assumption was that our target had 2 crystals, one for the internal and one for the I2C device.)

I suspect this may be causing the NFS timeout issue that the target board is experiencing? Perhaps, a workaround to this issue is to configure Linux to no use the internal RTC on boot?

Thanks in advance,

Rob

Rob,

I assume you've gone back to a full DTS or at least the one that has Ethernet our you wouldn't be able to get an IP address. I don't really see how RTC time could correlate to NFS not being able to connect, but I could be wrong. What else have you done to validate Ethernet on your custom board? You're able to boot from it, but NFS seems unstable and can't connect. Are you getting any messages on your host that might indicate what the problem might be?

It might be good to use Wireshark on the host to inspect the traffic and see what is going on on the wire.

I agree that RTC is very unlikely the issue, however it is a delta form the EVM and I wanted to note that.

Attached is a Wireshark pcap of the NFS session with our host. It demonstrates Fragmented IP packets??? I am trying to understand what this means, but can defer to your experience and knowledge base. Any assessment is appreciated.

Here is the console output form the Target board as well.

Further review of the Wireshark capture has revealed the following, see highlighted packets below:

The NFS client, IP 192.168.1.21 (out target board) is sending and RPC READ command for the systemd file and requesting a size of 4096 bytes? The response from the server is a Fragmented IP packet of 1514 bytes, not 4096. As this interface is using UDP I suspect that there is an MTU mismatch somewhere in my network?

I would like to limit the requested size from 4096 to 1500 or less. I suspect that Linux is getting the MTU size form the MDIO on the PHY we are using, the DP8322. I followed some examples on modification of the PHY registers through the MDIO in the devictree. Specifically, modification the fifo-depth, but still get the same packet request. This is my DT source for the the MDIO:

&davinci_mdio {

pinctrl-names = "default";
pinctrl-0 = <&mdio1_pins_default>;
ti,fifo-depth = <1>;
status = "okay";
};

Perhaps I did not do this correct or is there another method to limit the MTU on the DP8322 or anther method to change the request size in the RPC on Linux from 4096 to 1024?

Thanks in advance,

Rob

Rob,

This fragmentation does not happen when using the TI EVM, correct?

I found this article informative for tuning NFS:

https://www.slashroot.in/how-do-linux-nfs-performance-tuning-and-optimization

I agree is looks like some mismatch that must be root caused to the differences in h/w. I'm sorry, I don't know the PHY to answer the question of how to change the MTU size for it, so you might want to post a separate question to the PHY Forum to get their advice.

I hope this is helpful to you.

Ron,

Thanks for the response and your time in looking at this.

The fragmentation does not appear when using the TI EVM. In fact, the TI EVM interface is using 4096 size UDP packets without issue, so I am certain my network setup can handle the larger packets.

I did find in the Linux source that the default rsize is defined in net/nfs/nfsroot.c at

/* Default NFSROOT mount options. */
#define NFS_DEF_OPTIONS "vers=2,udp,rsize=4096,wsize=4096"

and changing the size to 1024 did remove the fragmented packets, but the NFS server is still timing out when it is being mounted.

Keep in mind that I am trying to boot our target using the am437x netboot boot option, so the NFS mount point is the rootfs. At this point our target has not booted and there is no command shell. The examples at the site you presented all need to have a command line interface. I am still trying to get Linux to complete the boot using bootp and NFS.

The change that our target has from the TI EVM is that the Microchip RGMII PHY on the EVM has been replaced by a TI RMII PHY. ( I have updated the device tree to use the correct pinmux and mdio settings for the TI PHY.) As well, I can successfully ping our target board while the NFS mount is timing out as shown above.

Any other insight on this issue are most welcome. I am suspecting a configuration/device issue with the updated PHY.

Thanks in advance,

Rob

I agree with your assessment. If working with the PHY configuration doesn't yield any positive results, please feel free to come back here and we'll see what we can do to help further with NFS.

Hi Rob,

I would like to verify some things at the network HW level and to do that we need to see the HW statistics of the MAC. We may need to do this in a couple of steps since NFS is having some trouble and this first step may still have the same issue. First step is to boot to a shell which will bypass the SystemD userspace, here are some links to booting to a shell. These were intended for SD card mounted root file systems.

Link to article on build booting to a shell

Link to video on booting to a shell

If you are still having trouble with the NFS with this shell approach the next step is to build into the kernel a minimal root file system. TI provides a minimal root file system in the Linux SDK. Are you famaliar with building the file system into the kernel?

I need to add a comment to the above discussion on MTU sizes, the CPSW cannot handle packets of 4096, the driver limits MTU to a max of 1522 bytes.

Best Regards,

Schuyler

Schuyler,

It was good to talk with you and engage on this issue, thank you for your time.

I created the shell script on my mount point as suggested. As well, I updated the optargs in u-boot and found that the kernel on my target does attempt to get the boot_app.sh and execute it, but it appears to be have having an issue with /bin/sh? I attached the wireshark capture from my host as I did not get a shell prompt from the console. See below:

I am not familiar with building the file system into the kernel, I have not done it before.( I am guessing the zImage will bloat quite a bit.) I will try to get some help on kernel.org or perhaps you can direct me to an E2E link?

Thanks in advance,
Rob

I have been unsuccessful at building an image with a rootfs embedded. Do you have any support pages or direction for building the image?

Rob,

We will put together some more specific instructions and provide them tomorrow.

Thanks.

0 RonB over 6 years ago in reply to RonB

TI__Mastermind 30636 points

Rob,

Here are some more specific instructions to get an initramfs based image that you can boot by putting the filesystem in the zImage via initramfs. So, you can tftp the new zImage over and boot to a Linux prompt. This will give us some new debug tools (i.e. ethtool) under Linux that we haven't been able to use.

Prepare the image for the initramfs. This is based on the "tiny" fs included with the SDK:

extract the tiny FS included in the /filesystem directory to another directory.
change to the new directory with the extracted tiny FS.
Use "ln -s /sbin/init init" to add an init link.
Copy ethtool from your NFS directory in /usr/sbin to /usr/sbin of the tiny FS as ethtool is not included.

Now we need to have the Kernel build this in via an initramfs.

Build the defconfig:
1. make ARCH=arm CROSS_COMPILE=/home/sitara/ti-processor-sdk-linux-am335x-evm-05.03.00.07/linux-devkit/sysroots/x86_64-arago-linux/usr/bin/arm-linux-gnueabihf- tisdk_am335x-evm_defconfig
Open menuconfig:

make ARCH=arm CROSS_COMPILE=/home/sitara/ti-processor-sdk-linux-am335x-evm-05.03.00.07/linux-devkit/sysroots/x86_64-arago-linux/usr/bin/arm-linux-gnueabihf- menuconfig

You should see something like below. Select "General setup" as indicated below:
You should now be able to scroll down to
You once again use enter to go into this and choose the folder where you extracted the files:
You can now save the changes and exit out of menuconfig.
Now rebuild the kernel
1. make ARCH=arm CROSS_COMPILE=/home/sitara/ti-processor-sdk-linux-am335x-evm-05.03.00.07/linux-devkit/sysroots/x86_64-arago-linux/usr/bin/arm-linux-gnueabihf-
Copy the new zImage (that now includes the filesystem) to the directory that you TFTP from (I use /tftpboot).

You should now be able to boot to a U-Boot prompt. You'll need to stop things at the prompt. Once there, you should be able to use "run findfdt" and "run netboot" to boot the kernel.

I've attached the log of my boot so that you can see what I did and what to expect. Once booted, you should be able to run ethtool.

Note: I used a USB network as that is what I had set up. You can ignore the USB related stuff as you are using Ethernet. I also did this on a Beaglebone Black, so you'll need to adapt some of the commands as necessary.

Here is my boot log:

/cfs-file/__key/communityserver-discussions-components-files/791/initramfs_5F00_boot.log

I hope this helps get you to a place where you can explore the problem with ethtool.

0 Rob Peipert over 6 years ago in reply to RonB

Intellectual 550 points

Ron,

Thanks for the instructions.

I am wondering if I need to update my netboot string in u-boot? Specifically is the bootargs: root=/dev/nfs? or do I need to specify a different mountpoint for root?

Also, the link for init above points to /sbin/init on tinyfs /sbin/init is also a link to init.sysvinit application. Is this correct of do I need different init script?

I have built the new zImage. (It appears to have compiled in the rootfs as the size has grown by about 4 times.) I can download the image and start boot but it still is getting stuck?

I have attempted several options for bootargs with same result, I get this boot listing.

Any other ideas that may be stopping the initramfs from creating the shell?

Rob,

I'm not sure. In order to do the best I could, I repeated the process on the AM437x EVM using PLSDK 5.3, which I believe is the exact same base you are working from. I also used Ethernet boot (as opposed to USB Network). Again, trying to minimize any differences that I can. Here is my log, and as you can see the shell starts up just as expected.

One thing I do notice is that we are getting quite different bandwidths. I realize you are using a 100Mbit PHY, but the numbers are still pretty far off.

Two things would be great to try:

Can you try this process on your AM437x EVM just to establish the same baseline?
Can you take a wireshark trace of the boot process, particulalry the kernel/FS copy to see what is going on on the link?

My log from the AM437x EVM:

/cfs-file/__key/communityserver-discussions-components-files/791/am437x_5F00_initramfs.log

Thanks.

Ron,

I will attached the wireshark capture to another reply on this link.

Here is the Terminal listing of the EVM booting on my system using netboot:

BTW: I ran the ethtool utility that was included in the rootfs with zImage.

Rob,

Looking into this further, we noticed that your console on your board is different than what we use, ttyS0 on the EVM vs. ttyS3 on your custom board. To account for this, inittab needs to be edited so that your init shell will use the correct console port.

The file is /etc/inittab in the tiny FS. It needs to be changed from:

S0:12345:respawn:/bin/start_getty 115200 ttyS0 vt102

to:

S0:12345:respawn:/bin/start_getty 115200 ttyS3 vt102

Then you'll need to rebuild the kernel (and FS into the kernel). What was essentially happening as you were booting but you were seeing no output on your console.

Can you please make this change and give it another try?

Thanks.

Ron,

I do have access to the Uart0 TX on the target and had been using that for debug output in U-boot and SPL, previously.

On the first attempt to boot the tinyfs I suspected that Linux may be defaulting to Uart0. I connected a terminal to both Uart0 and Uart3 and did not see a terminal on Uart0.

Just to be sure, I edited my inittab as shown below:

# /etc/inittab: init(8) configuration.
# $Id: inittab,v 1.91 2002/01/25 13:35:21 miquels Exp $

# The default runlevel.

# /etc/init.d executes the S and K scripts upon change

Now when I boot I am seeing a message from cpsw that the eth0 link is going up and down?? But no terminal of shell.

The target boot and terminal listing is shown below, it appears to be switching from HALF to FULL duplex???

Ron,

The Uart numbering got us. CPU_B which does in fact use ttyS3 booted to the tinyfs just fine. (Although the loading zImage had some tftp packets timeout.)

See attached capture of the terminal output when the ethtool command is executed.

I suspect C is booting fine, I just need to change console to ttyS4.

CPUB_tinyfsboot.log

Regards,
Rob

Ron,

After editing inittab for ttyS4 I can boot CPU C. However I cannot login as root?

I have tried to edit /etc/shadow file in tinyfs and remake the zImage with no change in tinyfs?

As well I copied a /etc/shadow from one of the rootfs used on the SD card that boots a devkit and I still cannot login?

Any other suggestions?

Regards,

Rob

This is what I get on the terminal

Hi Rob,

That is really good news on the boot. Thanks for posting the ethtool output. These are the error counts below that I wanted to see, the RX CRC errors are non-zero which ideally they should always be 0. Typically this a board layout issue between the MAC and what it is connected with. But I believe the board has been modified here and that may contribute to the CRC errors being seen.

Rx CRC Errors: 2
Rx Align/Code Errors: 0
Oversize Rx Frames: 0
Rx Jabbers: 0

Best Regards,

Schuyler

Schuyler,

The CRC errors are most likely related to the modifications we had to do on CPU B to get it to boot, it is a gnarly hack job on the PCB.

Most likely the wiring is ringing and susceptible to noise that is contributing to the CRC errors this is what the mod looks like.

Schuyler,

I was able to get passed the login issue on CPU C. I needed to add ttyS4 to the list of Standard serial ports in /etc/securetty of tinyfs and then rebuild zImage

I was able to boot and run ethtool on CPU C, the attached is the terminal output. It shows 1 Rx CRC errror???

Rob,

Eventually I think you want to look at what is causing the CRC error but for the moment is the link up/down happening?

Best Regards,

Schuyler

Yes, it still happens.

I attached the log output for CPU C.

Rob,

Thanks for the log with the ethtool output included.

Pause Rx Frames: 0
Rx CRC Errors: 55
Rx Align/Code Errors: 93
Oversize Rx Frames: 0
Rx Jabbers: 0

The CRC and Align errors are increasing and probably impacting the traffic. As I mentioned earlier these are most likely related to a layout problem. The link up/down is something related to the analog side of the PHY. Since this is a TI PHY being used I will contact the PHY team for assistance on some next steps.

Best Regards,

Schuyler

Schuyler,

I was able to boot CPU A and run ethtool on that interface as well, the attached is the terminal output. This target continues to show the CRC errors.

As a test I also attempted to mount my NFS after the boot to the tinyfs. This is how got it to work and what happened:

1) Copy the mount.nfs from an extracted "full" filesystem:

cp ~/targetnfs/am335x/plsdk5_3/sbin/mount.nfs ~/tinyfs_am437x/sbin/

2) Copy the shared library:

cp ~/targetnfs/am335x/plsdk5_3/usr/lib/libtirpc.so.3* ~/tinyfs_am437x/usr/lib/

3) Make the needed link

cd ~/tinyfs_am437x/usr/lib/

ln -s libtirpc.so.3.0.0 libtirpc.so.3

4) Rebuilt the kernel to pick up the changes to tinyFS.

5) As a test I ran this command on the my IDK to validate that my NFS server (192.168.1.9) is functional:

mount.nfs 192.168.1.9:/export/rootfs /media/nfs/

This mounted with success and the mount point showed the file system on the server.

6) I ran the command "mount.nfs 192.168.1.9:/export/rootfs /media/nfs/" on my target CPU A and found that mounted once out of about 10 attempts. The mount point was really slow, as I am sure there are timeouts and errors on the link.

So far I have been able to boot the tinyfs on all the AM4376 targets. Each target demonstrates the Rx CRC errors and Rx Align/Code Errors. As a check I booted the IDK on my network and found that it has 0 Rx CRC errors.

Perhaps the next step is to re-review the schematic and layout as you have suggested?

Regards,
Rob

Schuyler,

In searching the E2E forum for issues related to Rx CRC Errors and Rx Align/Code Errors we found this thread:

https://e2e.ti.com/support/processors/f/791/t/802339?tisearch=e2e-sitesearch&keymatch=processor-sdk-am57x

Then I searched the device tree sources in the Linux BSP and found that in arch/arm/boot/dts/am43x-epos-evm.dts it sets:

&phy_sel {
rmii-clock-ext;
};

After the cpsw_emac0 device definition.

I updated my device trees to include this component and found that all the Rx CRC Errors and Rx Align/Code Errors were zero on all the target am4376???

Then I backed out the changes in zImage to remove the tinyrs root file system.

I found that when the targets rebooted using netboot they connected to the NFS server, mounted the rootfs and continued to boot to a shell prompt without hanging.

BTW: I still needed to update securetty in my /export/rootfs/etc to include ttyS4 to get a terminal on one of the targets.

I appears that this device tree property has addressed this issue. Do you agree?

Regards,

Rob

Rob,

Excellent, yes I agree that changing the PHY clock mode is correct path here, it eliminates the errors. That was a great idea to search the forums, good find on the rmii-clock-ext. I will to keep this in mind to check this on future RMII setups.

So you are not seeing the link up/down messages after the DTS modification?

Best Regards,

Schuyler

Schuyler,

We have only tested on 2 of 3 targets but the link on all those 2 is not going up and down. I have been using one all morning mounted to NFS and it has no RX CRC errors.

Thanks in advance,
Rob

Rob,

Glad to see that the link up/down has gone away. I see the green box so does that mean you feel the issue is resolved?

I will click TI thinks to close the thread. If you respond again to the thread it will open up again if you need additional assistance.

Again, great find on the PHY mode clocking.

Best Regards,

Schuyler
