This might be my misunderstanding of how OVERRIDES work, but I'm building with the recently-released "wrynose_v26.02.18" branch of meta-st-stm32mp and, for the purpose of debugging, I wanted to set:ST_OPTEE_CORE_DEBUG = "y"so I did that in my local.c...
I get this issue in the booting process of Linux. Then nothing else happens, except outputs from Optee. F/TC:? 0 pta_scmi_ocall:207 Posting MSG message on channel 0 root '/dev/disk/by-partuuid/e91c4e10-16e6-4c0e-bd0e-77becf4a3582' doesn't exist or F/...
Hi~ My board gets stuck at the kernel stage during boot. I've referred to numerous related posts but failed to resolve the issue.The boot file versions I use are OP-TEE 4.0, U-Boot 2023.10 and Linux 6.6.116.The official device tree I referenced is st...
I wonder why this is happening after U-boot has booten up?It seems that something is NULL. D/TC:? 0 tee_ta_close_session:484 Destroy session Error: eth1@482c0000 address not set. D/TC:? 0 tee_ta_init_session_with_context:562 Re-open trusted service ...
Hello,I would like to ask about the current status of Bare-Metal support for the Cortex-A35 core on the STM32MP2x platform (STM32MP257F-DK).While searching the ST Community, I came across the following discussion related to this topic:https://communi...
I am developing an M33 application on STM32MP257F MPU, I would like to know the steps to import, build and debug secure project for Cortex-M33 in STM32CubeIDE for M33-TD flavor. I would appreciate if any one could tell the best and easy way to deploy...

I am developing a custom board using the STM32MP255F-AK.After configuring the kernel via menuconfig, the .config file reverts to its default state for some reason.The custom board settings and device tree are located in `meta-st-stm32mp-addons`.I hav...
Hello teachers, I am a developer of the STM32MP157F chip and would like to ask you a question about device tree configuration. Please help me. The version I am currently using is as follows: optee 4.10 uboot 2023.10 linux 6.6 ...
I ported PPSSPP 1.20.3 to run on the STM32MP257D platform.With the GLES backend, everything looks fine and normal games run without issues. But when I try heavier 3D games like Tekken 6, it gets extremely choppy – single-core CPU usage stays around 9...
