I have seen this error before and it has been on my todo list. So I have tried to fix it here [1]. Feel free to test it and let me know if you see any further issues.
Ah, nice, will test ASAP!
Meanwhile more food: I managed to build a firmware that was missing STMM. But the driver loaded, and I got this:
Thanks for the testing. I'll try to reproduce it locally and get back to you
Can you provide a bit more info on how that was triggered btw? I would be helpful to know
- OP-TEE version
Today's master, 145953d55.
- was it compiled as a module or built-in?
Sorry, not sure anymore, switching back and forth right now. I think it was built-in.
- was the supplicant running?
Yes.
Ok thanks, that helps. I guess this also means U-Boot was compiled to store the variables in a file in the ESP instead of the RPMB right? Otherwise, I can't see how the device booted in the first place.
U-Boot was not configured to perform secure booting in this case. It had RPMB support enabled, just didn't have to use it.
