Hi,
I have a problem with bringing up my custom board based on STM32MP135.
The problem is related to framebuffer optee

Hello @Michał Wołowik ,
The OP-TEE frame buffer is a secure memory region dedicated to the display, used by Trusted UI in OP-TEE, protected by TZC. This region named optee-framebuffer is configured in OP-TEE device tree source core/arch/arm/dts/stm32mp135f-dk.dts
The default configuration looks like this:
optee_framebuffer: optee-framebuffer@dd000000 {
/* Secure framebuffer memory */
reg = <0xdd000000 0x1000000>;
st,protreg = <TZC_REGION_S_RDWR 0>;
};Hope it helps,
Best Regards,
Kevin

Where can I find information on how to configure it correctly?
I attached my optee dts. Maybe someone with bigger experience than me can give me some hints.
Thanks a lot for any help

OK I think I found a solution
# Indicate which STM32MP package are used: 'A', 'C', 'D' or 'F'
CUBEMX_SOC_PACKAGE = "F"Previously was set to "C".

Hello @Michał Wołowik ,
So, you were able to boot your OPTEE?
Thanks to have provided more information and the solution that helped you to solve the latest issue, it will maybe help other people.
Best Regards,
Kevin

Hi Kevin,
Yes, I'm able to boot in OPTEE.
Critical for me was missing configured and enabled component named 'saes' and the wrong package chosen.
I tested many configurations in which I enabled and disabled a component like 'saes, pka, hash' etc.
Critical for me was 'saes'.
The optee is much more complicated than trusted. I prefer to use trusted but for this CPU the *.tsv files do not exist only optee. Without *.tsv You can't program Your memories (EMMC/SD-Card) via Cube Programmer.
Additionally, I discover that Cube Mx wrongly calculate MPU frequency. In my case, I see in Cube that MPU should work with 900MHz but U-Boot shows only 64MHz. I work around this using the rcc configuration from OlivierK and now have 650MHz on MPU. But this issue is a separate topic.
Thanks
Best Regards
Michal
