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...
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...
Hello, st:The board I have on my hand is stm32mp257f-ev1.Now I have a problem. The gstreamer cannot work properly when playing mp4 format video.Does the h264 decoder need to be activated or enabled?I run this commandgst-launch-1.0 playbin3 uri="file:...
Hello,I am running on a stm32mp255dak processor with Linux running on the A35 core and FreeRTOS on the M33 core. I am running the M33 core code out of DDR.I am seeing an issue where the M33 core performance takes a hit and missed deadlines when the A...
my code only made changes the io, no rtos, no interrupt, but it cost over 1 us. the picture is that io sta. and clock
