Hi @SATEESH_52 

Could you please provide more information on your setup ?

Why did you conclude issue is from WIFI driver when there seems to be a watchdog interrupt going to OpTee ?

Which STM32MP1 device ? Which board ?

Which ecosystem version (seems v4.1.00 according to kernel version) and if individual components (TF-A, uBoot, Optee) are the right one for this ecosystem version ?

Full console log ?

Regards.

Hi PatrickF,

I am not concluding wifi driver issue. This releated to OPTEE. Which I was using custom board (STM32MP133C) 

optee version - a1f02f4f3daae7e21ee58b4c93ec3e46b8f28d15 (HEAD -> master, tag: v2.6-rc1, tag: v2.6)

kernel version - 1.15.67

Hello @SATEESH_52 ,
It looks that your kernel just does not start, and so is not able to kick the OPTEE watchdog, that leads to a watchdog panic in OPTEE. (Linux is responsible to regularly kick an OPTEE watchdog that is a kind of heartbeat to check if the link is still alive).

So you have to find why does your Linux kernel not start.

Can you double check that all your SW component are aligned with the version waited with OpenSTLinux v4.1 ? (you can check the versions at this link : https://wiki.st.com/stm32mpu-ecosystem-v4/wiki/STM32_MPU_OpenSTLinux_release_note_-_v4.1.0#Release_content).

Kind regards,
Erwan.
