Hi everyone,I’m working on an STM32MP157F-EV1 board and encountering this error:warning: FBIOPUT_VSCREENINFO failed, double buffering disabledI’ve tried enabling framebuffer-related options, including enabling fbcon, fb, and other framebuffer configu...
Moved from MCUs section - STM32 is an MPU.Hi all,I'm developing a firmware for a custom board based on MP135 micro - baremetal solution.The board has a MMC memory (no SD card) to host both bootloader and storage area (Fat).I've added the FileX module...
I want to enable libgfortran on OpenSTLinux distribution package. Based on the information that i found on the internet I added the following lines to the local.conf IMAGE_FEATURES += "tools-sdk" FORTRAN = ",fortran" FORTRAN_forcevariable = ",fortra...
Hello, If I put my new machine conf and device tree in meta-st-stm32mp-addons I can compile device tree and my image without any error. But if I use my own layer meta-my-layer (in meta-st), machine config is used but I have this message : | make[2]: ...
HelloI am trying to debug M4 firmware on my custom STM32MP157C board.I have a reference operating system built with yocto on which this works correctly.I have to build system with a changed configuration and debugging of the same firmware is not work...
I'm using the Yocto-based OpenSTLinux embedded software on a STM32MP25x and I don't understand which portion of the SRAM1/2 is free to use at runtime.Aside from the first 4kBytes of the SRAM1 reserved for OTP shadow, can the rest be fully used, or is...
