Hello On a STM32MP1-DK2 discovery board, running the latest starter image, flooding the ethernet interface with SYN packages leads to a reboot of the system. This behavior is reproducible and appears after around 30 secs.I stress tested the network i...
Hi all,I'm developing a custom board based on STM32MP153 SoC, and I need to use the internal RTC. I also need to output its 32.768kHz reference clock from I8 pin.As stated at https://wiki.st.com/stm32mpu/wiki/RTC_device_tree_configuration, into the L...
Hello thereI'm not familiar with building linux for embedded systems. I need to build an yocto openstlinux distro with arm-ostl-linux-gnueabi-gcc to be able to compile at least simple "helloworld" on STM32MP157-DK1My extra packages in local.conf are:...
Hi!I'm in search of a better GUI programming path :) Now trying Xlib.Here is a simple program from the Internet#include <stdio.h> #include <stdlib.h> #include <string.h> #include <errno.h> #include <X11/Xlib.h> extern int errno; int main( void ) { ...
I faced crashes when implementing IPCC on M4 (Hard Fault Crash) and A7 (Kernel Ooops or dead system). Observations on M4: - Once I 'solved' the issue by disabling Uart7- Once I 'solved' it by removing the FreeRTOS (which was configured with CubeMX de...

With the Distribution Package for STM32MP1 I created my own machine (STM32MP151A) and I was able to generate a the flashlayout for both sdcard and emmc.I don't see any script to create the image for emmc, like `create_sdcard_from_flashlayout.sh`.Is t...

Hello,Is there any STM processors that can run OpenSTLinux and support 3 lane MIPI DSI? I was planning on using STM32MP1 series but it only supports 2 lanes. Thanks!
I am confused by the different packages ,Starter, Distribution and Developer.Which one do I need to install/setup/build to have as the end result a "minimal" cli/shell based SD card image with support for all hardware on the DK2 board ? a "clean" ro...
