Hi all,I am trying to get 8th programming language fully working on OpenSTLinux. Currently, it almost fully works, including KMSDRM and Wayland backend suppport using SDL3 for Nuklear based GUI.There seems to be some problem using FFI and libc. "libc...
Hello everybody.On STM32MP2, is it possible to operate only the M33 like a microcontroller, without booting the A35? Also, if only the M33 is operated, can major peripherals such as I2C and Ethernet be controlled from the M33? (I assume that PCIe wou...
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...
