Hi all, having an issue with programming STM32MP257F-DK/SDCard with the Starter package getting to the stage in the attached screenshot then it seems a connection times out with no success notification popup ?
Hi,based on the information I get from the schematic of the STM32MP257-DK development board, I'm trying to develop a small embedded board that comes with much less interfaces and therefore is much smaller than this development kit board. Namely it wi...
The kernel is complaining that the specified root partition (identified by the PARTUUID) is not found or isn’t valid, and this is happening at the kernel level rather than in U‑Boot. In other words, U‑Boot is simply passing the kernel command line (w...
So first of all I'm working on creating a yocto image for this board.https://www.seeedstudio.com/Odyssey-MP135D-eMMC-p-5728.htmlMy end goal is to create a meta-layer with an easy to follow yocto quick start guide for this board similar to the one Se...
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...
