Hi, I am working with STM32MP157A-DK1 board with Yocto build system.I am trying to build synchronised system, that means I want to synchronise both CortexA7 and CortexM4. Basically I want to have the same time at both of them. I want to use STGEN for...
Hi everyone,I'm currently working on the PCIe part of the STM32MP25 and would like to ask if there's anything wrong with my configuration. I’ve followed the official documentation provided by ST.Here are the documents I’ve referenced:PCIe device tree...
Hi all,I'm working on a custom STM32MP135 SOC hosting a MMC memory. The original firmware creates some tasks by the osThreadNew() function and works correctly.Now I'm inserting FileX module on the firmware to support a FAT fs on the MMC memory.The fi...
I am trying to control the LTDC on the STM32MP257FAL based on the STM32MP257F-DK board, but I am unable to configure pin PH4. This pin is used as LED1 on the STM32MP257F-DK board, which is the LED near the button. However, I cannot find where this pi...
I am using the STM32MP157F-DK board and attempting to connect an NXP Wi-Fi + Bluetooth module via SDIO through the 40-pin expansion header. For this, I designed a custom PCB with an SD card holder and connected the SDIO lines from the expansion heade...
I have created a CubeMX project for STM32MP235.I have successfully built, Flashed and able to boot it on STM32MP257-EV1 board. (I don't have my 235 custom board ready yet.)Once I switch to normal boot after flashing, it runs until kernel tries to run...
I'm trying to update linux kernel on OSD32MP1-RED board to the latest kernel 6.6.78 that's provided with Developer Package using instructions in README.HOW_TO.txt.stm32mp1, but after building and installing kernel and modules on SD card booting from ...
I'm currently evaluating an embedded linux system for a specific use-case with my company.What's necessary is a lot of specific interfaces, like MIPI-DSI/DisplayPort/HDMI, USB HS (+PHY) and the standard RAM and other peripherals. I've found the STM32...
Hello everyone ! I use the stm32mp257f-dk with yocto for a project. To benchmark my programs, I need kinda heavy packages. To solve my IMAGE_ROOTFS_MAX issue, I followed the following topic : https://community.st.com/t5/stm32-mpus-embedded-software-a...
Hi everyone, for learning purposes I’m trying to build meta-doom for stm32mp257 DK. I previously tried it for RPi4 and after some minor fixes I was able to do it for nanbield/mickledore poky version. What I established it is possible to run it and it...
