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...
Hello all, I am following the following guide: https://wiki.stmicroelectronics.cn/stm32mpu/wiki/STM32MP25_Discovery_kits_-_Starter_Package In order to bring up a STM32MP257F-DK board and am running into a problem when I try to use the Programmer to f...
Hi everyone,I'm a beginner when it comes to STM32 MPU, and from the very beginning I've had an issue with the HDMI output on my STM32MP257F-DK board, which I received from my university. Naturally, I wanted to start with the Starter Package to explor...
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...
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
