Hello guys,As per the subject, where can i find a guide about starting new OPTEE port? Unfortunately i didn't find anything descriptive enough in the WIKI. Being stm32mp151c additionally complicates the matter as all supported platforms are '157x. ...

Hi everyone. I'm tasked with porting ST's most recent TF-A, u-boot and kernel to a custom stm32mp151c-based board. It runs 2021 version of the above SW components just fine.It seems, however, that at some point the device-tree bindings changed and ...
I built an st-image-weston by using yocto recipes. The layers is in oe-manifest branch scagraph (https://github.com/STMicroelectronics/oe-manifest) I got those warning, please help to fix it. WARNING: st-image-weston-1.0-r0 do_create_flashlayout_co...
hi there I have a question about Memory 。Are the memory regions starting at 0x10000000 and 0x30000000 part of the same mapped area?Are these addresses written the same way in the device tree, or is there a difference between them?thanks，csm
Hi,just a quick question to understand the hardware of the STM32MP257 development kit board: there are several ESD-protection components of type HSP051-4M10 used.What is the exact purpose of them, are they therea) because the DK-board is intended to ...
Hi, I am working with an STM32MP157CAA Rev.Z on a custom STM32CubeMX board running OpenSTLinux 6.6 (Yocto Scarthgap MPU v24.11.06). I have successfully integrated and bootstrapped various boot components.I first got the TF-A and OPTEE to boot the sys...
Hi all,I am trying to get 8th programming language fully working on OpenSTLinux. Currently, it almost fully works, including KMSDRM and Wayland backend suppport using SDL3 for Nuklear based GUI.There seems to be some problem using FFI and libc. "libc...
Hello everybody.On STM32MP2, is it possible to operate only the M33 like a microcontroller, without booting the A35? Also, if only the M33 is operated, can major peripherals such as I2C and Ethernet be controlled from the M33? (I assume that PCIe wou...
Hi,on the STM32MP257-DK board, the wires between the MPU and the RAM have an interesting shape:What is the reason for these non-direct wires? Have the same length for all the wires? Shielding? Some noise-thingy?Thanks!
