Hi,on the STM32MP257-DK board, the wires between the MPU and the RAM have an interesting shape:What is the reason for these non-direct wires? Have the same length for all the wires? Shielding? Some noise-thingy?Thanks!
Hallo,I have bought STM32MP135F-DK - Discovery kit and I was working with it few days. I don't know what happened, but today the kit will not work properly - I think the image on SD card is corrupted, some files might by changed or deleted, so I see ...
I have made a custom board with stm32mp135f and now trying to build linux for the custom board.I followed https://wiki.st.com/stm32mpu/wiki/How_to_create_your_own_machineand then run:bitbake core-image-minimaland after 98% got the following error:""E...
Dear Team, I recently brought STM32MP257-DK. I am able to explore the A35 part. Also I am able to run the example projects provided by ST for M33 core. Since My application will have more dependencies on the Realtime and hence I wanted to create a se...
Hi,I'm trying to run the whole ST-Linux-stuff on one core only to have the other one available for a time-consuming application. However, it seems the kernel-parameter isolcpus is not used, dmesg gives an output[ 0.000000] Kernel command line: roo...

Hi,when the STM32MP257F cores are running a regular Linux: how can I start some code on the M33 core? Is there a device/interface available within Linux that allows to send some code to this core and execute it? Or do they share some memory? So how i...
