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...
Can someone explain how to build own custom yocto linux ?I have experience with raspberry pi, but stm32mp2 have none normal explanation.I have cloned from git scarthgap branch of poky, meta-openembedded, meta-st-stm32mp and meta-st-openlinux. Also, I...
Hi, I'm doing a custom hardware design. I'd like to use LPDDR4 but only at 16bits of data width.Is there a list of LPDDR4 parts from Micron, ISSI, or others that are known to work with the STM32MP257?Are any parts that claim LPDDR4 ok?Thanks,John
I'm very proud of STM32MP1 and I want to continue to learn more about the STM32MP products.So, I'm planning to create another single board computer such as the open source project STM32-Computer. My next project will be STM64-Computer, which will use...
