Hi Team,
We are observing a stuck-on mcu M4f log on mcu M4f uart port after running for some time.
The time is not periodic it varies from 45m hr to 3 hr. It will fail at any time.
Use case: We are sending the data from the Linux to MCU M4f through IPC.
Thanks and Regards,
Aneesh
Hi Aneesh,
Could you please attach the log and details on what software you are using to verify the IPC mechanism on AM62x?
Is it Linux SDK or MCU+SDK software?
This will help route your query to the right expert.
Best Regards,
Suren
Hi Suren,
We are using Linux SDK and MCU+ SDK.
We are testing the IPC mechanism between A53 and m4f.
The applications are custom developed for both A53 Linux and M4f freertos based on the TI IPC examples.
We are not seeing any errors on the MCU log other than freeze. But after the MCU log got freeze we see some IPC errors on A53 side.
I am attaching the ipc error logs for reference.
Thanks and Regards,
Aneesh
Hi Aneesh,
Thanks for the logs. I have routed your query to our expert. You should be receiving a response soon.
Best Regards,
Suren
Hello Aneesh,
Can you please share steps to reproduce the issue ?
I understand that IPC operations between A53 and M4F cores are not working.
Is it possible to share your examples? so that I can review and provide my comments.
Regards,
S.Anil.
Hi Anil,
Myself(Vadivel) and Aneesh who created this ticket are working for the same company/project/team.
We run for 5k cycle and it stuck at randomly. Sometime at 2k+ cycle and sometime 3k+ cycle; sometime success also.
Note: Our code is similar to TI-sample code.
Regards,
Vadivel
Hello Vadivel,
Is it possible to share a reproducible code to me to verify at my end?
Along with that, could you please share your test procedure to reproduce the issue from my side?
Regards,
S.Anil
Hello Vadivel,
Can you please confirm the issue was happening in your custom HW or EVM?
If it is custom HW, can you please confirm on EVM if the issue was happening on EVM or not?
Regards,
S.Anil.
Hi Anil,
Right now, it is happening on custom hardware. I have made some more code changes to it and re-testing it now. I will update to you the result.
Is there way to enable more logs on m4f-image side? to see where its get stuck.
Regards,
Vadivel

Hi Anil, I have tried the TI IPC_RPMESSAGE_LINUX_ECHO example on both customized and evm boards. I am able to reproduce the stuck issue on both boards.
I am attaching the logs of both boards for reference.

Please help us with this issue.
Note: We can also debug this directly on our customized board if we can get on a call. I request you arrange a call or tell us the available timing to arrange one so we can debug this on the customized board directly.
Thanks and Regards,
Aneesh
Hello Aneesh,
Thanks for your input.
Let's discuss at 3:00 PM IST today.
Please let me know if it works for you.
Regards,
S.Anil.
Hi Anil,
The proposed time works with me. Can you please schedule the call?
Regards,
Aneesh
Hi Anil,
Thank you for the link, I will join the meeting at 3 pm along with my other colleagues.
Regards,
Aneesh
Hello Aneesh,
I have posted your issue to Linux experts and asked them to help debug it further on the Linux side.
I will post his availability, and based on that, we can have one more debug call. Since the issue mostly belongs to the Linux side and I am not an expert on Linux, So, we can take help from Linux experts as well.
Regards,
S.Anil.
Hello Aneesh,
Yes, now we don't need to connect.
I will inform you based on the availability of Linux experts.

S.Anil.
Hello Aneesh,
Have you connected to the M4F core with CCS to see what the M4F code is doing when it is in a "stuck" state? I am not seeing any Linux error codes, etc that give any Linux-side information.
Reference this e2e FAQ:
https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1188177/faq-am62x-am64x-how-to-use-ccs-to-debug-a-running-m4f-core-that-was-started-by-linux
Regards,
Nick
Hi Nick,
I will try that, I have some problems with my setup right now.
As this is happening on the EVM. Can you please try to reproduce the issue on your side and provide the fix as soon as possible?
In the mean time, I will try to debug using CCS once my setup is back.
Note: Please consider this issue as an urgent topic because currently, we are stuck because of this issue.
Thanks and Regards,
Aneesh
Hi Nick,
I trying with the on-chip debugger using the UART cable on EVM. When i load and runt the ipc.out file i am only getting below
[IPC RPMSG ECHO] Version: REL.MCUSDK.08.06.00.12 (May 19 2023 11:31:13):
instead of
[IPC RPMSG ECHO] Version: REL.MCUSDK.08.06.00.12 (May 19 2023 11:31:13):
[IPC RPMSG ECHO] Remote Core waiting for messages at end point 13 ... !!!
[IPC RPMSG ECHO] Remote Core waiting for messages at end point 14 ... !!!
Because of this i am not able to runt the rpmsg example on linux and cannot debug this.
As i have requested you yesterday test on your side. If you have tested , Could you please update your experiment results.
Thanks and Regards,
Aneesh
Hi Nick,
I am able to debug the ipc example with the help of your FAQs.
But when the stuck is happening I see the core is in still a running state.
I need your help to debug this furthermore to fix the issue.
Thanks and Regards,
Aneesh
Hello Aneesh,
Can you please share reproducible code on EVM? so that we can better assist you.
Along with this, please share the test procedure as well to reproduce the issue.
Regards,
S.Anil.
Hi Anil,
I have mentioned this in our debug session. This is the same TI ipc_rpmsg_linux_echo example. No changes.
mcu_plus_sdk_am62x_08_05_00_14/examples/drivers/ipc/ipc_rpmsg_echo_linux/am62x-sk/m4fss0-0_freertos/ti-arm-clang
After our debug session, I thought you are trying to reproduce the issue on your side and I am a little surprised by your question about the code.
On Linux, i am running this example rpmsg_char_simple -r 9 -n 10000. This is also available in roots by default. (No chnages).
Please help us in solving this issue as soon as possible. Also, If you have any pointers to debug the m4f furthermore because the status of the m4f core is in running when i saw stuck in the uart log.
Regards,
Aneesh
Hello Aneesh,
As mentioned earlier, I am not familiar with the Linux side and will take help from Linux experts to reproduce the issue.
Actually, I have jumped to another customer issue. So, I could not reproduce it.
I can try to reproduce the issue next week.
Regards,
S.Anil.
Hello Aneesh,
I have followed below steps to reproduce the issue .
1. Placed the WIC image for the 8.5 version on the SD card.
2. Kept the HW in SD boot mode.
3. Given the command rpmsg_char_simple -r 9 -n 10000 on the Linux UART port.
I have verified three times, and three times I am not getting stuck in M4F core . Please see the below image.
Please help me reproduce the issue if I did anything wrong.
Regards,
S.Anil.
Hello Aneesh,
Ok, let's pause for a minute.
Get to a known good state
First, please go through the steps here without making any changes (this includes creating a fresh SD card). I want to make sure you have a "known good state" to start working from:
https://dev.ti.com/tirex/explore/node?node=A__ACKtJpWz8b53RwT-PJ4qmA__linux_academy_am62x__XaWts8R__LATEST
This earlier page also has useful information:
https://dev.ti.com/tirex/explore/node?node=A__AISILbMWZ4d84U2oSmXcdA__linux_academy_am62x__XaWts8R__LATEST
Once you have a known good state, you can start making changes to the known good state one at a time until you find the change that caused problems.
Using CCS to debug the hanging state
The point of connecting CCS is to attach to the M4F core, is that you can pause the M4F core and see what the core is doing while it is paused.
See the yellow pause button in the upper left corner of the screen? Click on that, and you will be able to see exactly where the M4F core is and what it is doing.
This is an important tool when you are debugging your M4F code.

Nick
Hi Anil,

Hello Aneesh,
I have tried 5 times for 1 lakh iterations to reproduce the issue and have not faced any issues.
Please look at the image below.
Regards,
S.Anil.
Hi Anil,
Thanks for trying again, It is very confusing now, I have tried this today also it is reproducing on my side.
I want to make sure this should not be due to the SOC we have on EVM. We have XAM6254ATCGGAALW.
I know this point may not be an issue, But can you please confirm, You are also using the same SOC type on your EVM?
regards,
Aneesh
Hello Aneesh,
I have the same SOC mounted on my EVM as well, and there is no difference.
May I know what procedure is different with respect to your test procedure?
Have you changed any IPC codes? I know you have not updated, but can you please confirm?
How can I help you here?
Regards,
S.Anil.
Thanks for confirming it Anil, There is no difference in the code. I have made only one change in the code to see logs on mcu uart.Pleae check the code snippet below.
Hi Anil,
I have an interesting observation, I think the logs are the issue. If I enable the logs on MCU UART we see the stuck, If we disable the logs then we don't see any stuck.
Can you try enabling the logs, like I tried before the post and please let me know if you can reproduce the issue.
Hello Aneesh,
Yes , I have also suspected the same thing. since the only difference is enabling MCU UART log.
Let me check my side, and I will share the test results.
I suspect the issue comes up in two cases.
1. The same MCU UART can be used in both cores.
2. UART log settings

Hello Aneesh,
I am able to reproduce the issue and debugging why the MCU core is getting stuck in the debug log function.
Please allow me some time to work on it, and after I find the root cause, I will share the details .
As of now, you will disable the UART log and move forward.

S.Anil.
Hi Anil,
Sure,
Thank you for trying, Please let us know once you have new observations.
Thanks and Regards,
Aneesh
Hi Anil,
If you found any new observations, please let us know.
Thanks and Regards,

Hello Aneesh,
As mentioned above, I have noticed that SOC is hanging in the DebugP_log function, and control is not coming out of that function.
This is a library function and needs more time to be debugged further. So, I had a discussion with the design team and raised a bug for further check by the design team, and I will update the status once they find the root cause.
As of now, you will disable the UART log and move forward.

Hi Anil,
Is there any update on this topic, We need logs for debugging because we don't have a debugger for debugging.

Hello Aneesh,
Please try to use UART in polling mode instead of interrupt mode to print logs to see if you face problems or not.

Hi Anil,
Thank you for your reply, I will try on my side, can you also please try from your side?
Thanks and Regards,
Aneesh
Hello Aneesh,
I have already tried it, and it is working fine for me.
So, that is the reason I have asked you to use UART in Polling mode.
Please try polling mode and share the results.

S.Anil.
