Hi guys.i can quickly and easily access SYSRAM in engineering mode.i read in RM0436 Reference manual:backhand_index_pointing_down: SYSRAM is implicitly allocated to the MPU. So there is no enable bit for the MPU to allocate this memory. But when the...
I want to use a Winbond W25M02Gxx 256MByte (2x1Gbit) on MP157 QSPI1 port. It seems that the boot mode supports the use of Serial NAND Flash.Anyone tried this?
Hi everyone,Can I assign, for example, UART to Cortex M4 runtime context, and generate appropriate device tree files for STM32MP1, and then after boot, reassign UART to Cortex A7 runtime context somehow? Best regards, Nenad
Hello everyone,I managed to build st-example-image-qt on my STM32MP157C-DK2 with some extra image features.Now i just want to run bitbake meta-toolchain-qt5 but the build end up with errors that i can't solve.I attached the output console when i try ...
Hi,I want to generate a new distro for MP1 with distribution package and qt-examples. I downloaded all of the packages via fetchall command to avoid getting an internet connection error during generating. After that, I have tried to generate an image...
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...
