I have a custom board with a stm32mp151c and 256M DRAM.Trying to get optee 3.12 from ecosystem 3.0.0 to start.Everything works fine with tf-a 2.4-r1 and sp_min, u-boot 2020.10 etc.But I can't get optee to start. I've enabled a high loglevel and the l...

https://github.com/STMicroelectronics/meta-st-stm32mp/blob/kirkstone/classes/fip-utils-stm32mp.bbclassFIP_SIGN_KEY is used to specify the rot key.But if that key is not found (wrong path for example),the bbclass and cert_create silently creates a new...

My TF-A on the stm32mp157f-dk2 is built with all the proper parameters.The FSBL is verified on a fused public key hash, but the device is not closed.I can see that the FSBL has a successful authentication.So I decided to check on the TBB CoT over the...

To detach signing from cube programmer I made an open source C signing tool, using openssl. Should be rather easy to use in various build environments.https://github.com/milkylainen/stm32mp1sign

Hi @Community member,No I don't really see an issue. It's just surprising.I came from sp_min without such restrictions.I didn't look at the code because I was pretty sure I was doing something wrong.And available documentation did not imply any rest...

Oh.That would explain a lot.But I can't find any documentation about it.Seems pretty critical...If your intention was that OTP programming is disabled,that would mean two different op-tee variants.One for factory and one for runtime?

So. Tried 3.1 with stm32key close.Didn't do any difference. Same error.

I thought it was obvious that this was an early ecosystem 3.x version,esp. since I stated TF-A 2.4-r1 and optee 3.12-r1. Apparently not. My bad.So. Ecosystem 3.0. You don't have stm32key close in < 3.1.https://wiki.st.com/stm32mpu-ecosystem-v3/wiki/H...

Deceptive default behavior from cert_create and fiptool bbclass.
