SK-AM62A-LP: How to debug the reset reason when the evm board is being logging into A53 linux

Hi,

Please refer to the below thread for the flashing & SBL booting issue

SK-AM62A-LP: flash EMMC using default_sbl_emmc_hs.cfg error - Processors forum - Processors - TI E2E support forums

Once this is resolved, we can look at the Linux booting issue if it still persists.

Regards,

Prashant

Thanks for your reply, that my flash issue is the same like that item. And I can flash the internal emmc right now. But the reset issue is still there. At this point, ho w to find the reset reason?

Hi,

I infer that the flashing & SBL booting issue is now resolved but the Linux reset issue still persists.

In that case, could you please try the PSDK original boot flow (tiboot3.bin -> tispl.bin -> u-boot.img -> Linux Kernel) & see if the Linux reset issue is there. This is to confirm the Linux reset issue is not because of using the Linux SBLs boot flow from MCU+ SDK.

Regards,

Prashant

The board will reset no matter which boot mode  was selected. I download the original wic.xz image and flash into sd card, it reset too. In on word, it will reset during booting into linux for all. I reflashed the board dozens times, and only worked two times.

Hi,

Thank you for doing the test.

It seems this is a Linux Kernel issue. I am passing the thread to the subject matter expert. You should be getting a response by EOD.

In the meantime, please share the working logs (when the Linux Kernel boot fully) & the non-working logs (when the Linux Kernel resets) when using .wic.xz image.

Regards,

Prashant 

But I can't paste long log. how to share?

You can use the following reply feature to attach the logs

If I paste a too long text, it will reject with message:

Access Denied
You don't have permission to access "http://e2e.ti.com/tinymce/apis/embeddables/configure?" on this server.

Reference #18.240ae07a.1705919121.1f7f59c9 

Interesting. Can you save the logs as text files & then use the drag & drop feature to attach the logs files. That should work.

Sorry, I have to upload the long logs to temp website, and the issue log is at https://pastebin.com/dz0qZPJi, and the right log is here: https://pastebin.com/z9Vt1gBb

And, is there any method to capture the reset point?

Hi,

I am unable to access pastebin. Can you please save the log to a file and attach it on this thread?

What power supply do you use on SK-AM62A-LP? Please ensure it is type-C, at least 5V 3A.

Yes, I use upto 5V 5A type-C power supply. And I know how to attach local logfiles into the thread now. Please have a look at them:

Hi,

It seems the log files are not attached correctly. Clicking the links lead to "Page not found" error.

Can you please double check the uploaded log files?

I think its the problem of the host of e2e, all the same no matter how many times I tried. I have to re-upload to pastebin without expiration:https://pastebin.com/CH9A5hun, https://pastebin.com/tLuMfjG8

If you can't open them, I think I would have to send it by another way, by email, etc. Thanks

Hi,

Postebin is blocked in our network. I cannot access it.

In your reply compose window, click "Insert" at the bottom of the window, then click "Image/Video/File", then in the new pop-up window, click the grey "Upload" right under the "File/URL" field, which should allow you to select the file and attach it.

Yes, I used this method before, but all can't access. Please wait me a while, I split it shorter and upload as several texts.

You can also zip the log and attach the zip file.

still not accessible. can you please try a different web browser?

I retried with chrome, the problem still there. would you line provide me another way to upload the log?

I have to upload the issue log and worked log to another site:

https://app.simplenote.com/p/HBphFq

https://app.simplenote.com/p/KVp82G

I hope it will not be blocked right time. Thanks

Hi,

I don't have access to simplenote either.

I have sent you friendship request. Please accept it and I will provide my email address, then you can email me the log files.

Any hints will be very appreciated, like how to debug it to find the problem. And, the boards will reset if booting into linux, no matter which bootmode I used.

some time I can see the last uart log before reset:

Hi,

Thanks for send the boot log offline. The log shows SBL booting Linux. Can you  please following the instruction below to flash the Processor SDK Linux prebuilt  SD card WIC image to a SD card and boot your SK-AM62A-LP with this SD card? I'd first like to see what issue you would have without using SBL to boot Linux.

https://dev.ti.com/tirex/explore/node?node=A__AQniYj7pI2aoPAFMxWtKDQ__am62ax-devtools__FUz-xrs__LATEST&placeholder=true

Will got the same result. I have do further debug test and found the reset due to the linux's udev service. I think that should because wk-r5, mcu-r5 and a53 get touch each other leading some further issue. But, I do not now how to pause before its reset.

Hi,

Can you please share the details? What makes you conclude the issue is udev related?

1）The board will reset while booting into linux, no matter the boot mode is

2)  If I hit enter key at a53 uboot and stay there, the board will not reset

3) If I remove /sbin/init in the origin filesystem, (sd card and emmc), the board will not reset now

4) I replace the init system from systemd with sysV, the board will not reset if I remove udev service

So, I guess the reset issue due to multi cores

Sorry of slow response because of the weekends. I had tried again, it still reset although I had disabled all the remote cores. And the latest linux log is:

I have tried many times at the last weekends, and got success finally. I disabled almost all peripheral devices and still reset. Since the board worked well without any modification but only do re-flashing operation  two times before, I still re-flash via uart many times. It works now, I will keep the current status and will not flashing it via uart agin.

Thanks
