AM625: The core kernel crash issue

Hi Liang,

It seems the kernel Oops is triggered by USB. Can you please describle your USB use case? What operation triggers it?

Is this happening on AM62x EVM or your custom board?

Please attach the full kernel log including the crash messages.

Hi Bin,

This is urgent, so please kindly review the log and provide your commend if there are any more improved, thanks.

The kernel crash happens about 40 minutes after Linux is booted. Can you please explain what the system was doing during this time? We first need to understand what triggered the crash, the log doesn't expose much.

Hi Bin,

So you mean we need to send all the log in the 40min, this maybe to long and I will send to you tomorrow. thanks.

Hi Liang,

Can you please first explain what the system is doing? Any application is running which might trigger the crash? or you didn't specifically start any application?

As of now I at least don't have any clue what could trigger the crash. The logs you provided so far do not provide the source of the crash.

Hi Zexian,

Does the issue happen on multiple boards?

If you do not run your Qt program, does the issue still happens?

Hi,Bin,

Test a day time, if do not run the qt program, the kernel does not crash, what is the reason?

Hi Bin,

Run qt, a total of three new boards, two boards have a kernel crash, one board test normal

Hi Zexian,

Please first check all the power rails on your board and ensure they all meet the requirements on the Datasheet.

HI Bin,

We use a special PMIC chip TPS6521901 power supply, the power supply has been tested

Hi Zexian,

Thanks for the details. It does sound like a software issue.

I am routing your query to our Qt/Gfx expert for comments. He is currently out of office for the next 3 weeks. Please expect delayed responses.

Hi Bin,

Could you check the problem as soon as possible, because our company needs to make the finished product in one or two weeks

Hello,

Is there a way to replicate the issue on TI EVM? For example, if you run the Qt program on TI EVM, do you see a similar issue?

Regards,
Krunal

Okay, in order to isolate the problem from Qt and GPU, could you try running glmark-es2-wayland or kmscube? Let's see if with standalone applications, you also see kernel crash and please capture the logs while running the applications.

Regards,
Krunal

Hi .we run the kms command  . the kmscube can't  work . the information is below.:

so how to run kmscube correctly . I found in link on the e2e .but I can't open it .  processors.wiki.ti.com/index.php

could you give some advices as soon as possbile ? 
Thanks very much!

Hello,

Step 1: Stop Weston using the command "systemctl stop weston"

Step 2: Run kmscube "kmscube -D /dev/dri/card0"
Step2A: For modetest, the command is modetest -M tidss

Regards,
Krunal

Hi,we have test the kmscube .   kernel crash at  2.6 hours.

Hello,

Unfortunately, the logs do not tell much about the issue and it's a generic log. 

Do you see similar behavior if you try the following tests:

Test 1: Disable GPU and try running CPU based display tests
rmmod pvrsrvkm
glmark2-es2-drm 

Test 2: Run a CPU stress tests to see if it triggers the issue

stress-ng -c4 --cpu-method=all

Regards,
Krunal

Hello， I have run the 2 tests.
test1: it is not work .

For test 1, could you migrate to 9.0 SDK because it seems like you are using an older release?

For test 2, how many ARM cores do you have on your custom board?

Regards,
Krunal

we now use 8.6.0.42 sdk .
we use AM6254, 4 cores on the board.

Is it possible to migrate to newer SDK? What kernel version are you using and have you made major modifications? We do not see the same issue on our software running on our EVM.

Regards,
Krunal

now  I am migrating the newest SDK 9.0. 
 

The SDK8.6.0.42 kernel version is  5.10.168.and we didn't do modification. we just change RAM size to 512M(0x20000000).

What changes did you make in Uboot and Kernel for 512MB RAM? Also, please post your changes/logs/diffs in a text file and do not just copy/paste your code.

Regards,
Krunal

Okay, that looks okay to me. Let's see the behavior of your board once you migrate  to 9.0 release. 

Regards,
Krunal

HI，I have migrated to 9.0 release . 

and do the 2 tests:

Test 1: Disable GPU and try running CPU based display tests
rmmod pvrsrvkm
glmark2-es2-drm

the error is below:

the applcation just run about 10s then killed .

Test 2: Run a CPU stress tests to see if it triggers the issue

stress-ng -c4 --cpu-method=all

the test2  run  successfully  for 12 hours  ,but there is some print information during running .

Is this normal ?

HI，we test  board again with stress-ng -c4 --cpu-method=all.

the system run for 16 hours then we kill it by manually.

the run information is below. I want to know if it is normal ?

sdk-9.1.0.8-stress-ng-info.txt

Hello,

After killing the test, did you see the Kernel warning or it happened during the test run?

Regards,
Krunal

NO.now it runs ok when we have test on the two hardwards. we have made the third verison of hardware . it may the DDR4 problems.

Thank you for the update! Please keep us posted on your DDR4 analysis.

Regards,
Krunal
