AM62L-PROCESSOR-SDK: OP-TEE Probe Failure During Boot and xtest Failure

Dear TI Support,

I am encountering an issue with optee on the AM62LX platform. encountering an issue where the OP-TEE probe fails during boot, as observed in the boot log(). Additionally, when running the xtest command, I see the following output.([ 0.986829] optee firmware:optee: probe with driver optee failed with error -22)

Run test suite with level=0TEE
test application started over default TEE instance
Failed to open TEE context: 0xffff0008

Could you please provide guidance on whether this is the correct way to verify OP-TEE functionality? Additionally, I would appreciate any insights into potential causes for the probe failure, steps for debugging, and necessary configurations in U-Boot, the device tree, or ATF to ensure OP-TEE is correctly loaded and functional.

Looking forward to your response.

Regards,
Dheeraj K
