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...
Hello,I am struggling with improper color management for our display connected as LTDC. I prompt for drm state with cat /sys/kernel/debug/dri/0/stateI wonder why I get format=RG16 (that is true, we use RGB565 LTDC interface) and color-encoding=ITU-R...
Dear all, we use custom board with STM32MP1 SoC onboard. We use Yocto with OE, STM, Qt and custom layers for building target images. In our device we utilize 7-inch display connected by LVDS with RGB666 wiring. If I load bitmap image from U-boot, a...
