Hi,in schematic of the STM32MP257-DK-board, I found the following resistors at the Ethernet interface being marked with "DNF":When looking at the board, these resistors are missing (which should be "DNP" in this case?).From my understanding of the wi...
Hello,I use STM32MP1 SoC. According to wiki I can interrupt uploading images with STM32 Cube Programmer via USB-DFU: For USB boot, you can easily interrupt this command stm32prog usb 0by pressing Ctr + C in the console without U-Boot modification. U-...
I have a custom yocto project based on stm32mp157c. I have developed the bootloader and linux kernel.I have display functionalty and display is working perfectly. But now I am changing the display, because the display will be discontinued. The device...
HelloWe are currently working with the STM32MP257F-DK board and attempting to toggle the GPIO pins on Port Z. However, we have observed that the mode of the pins in GPIO Z remains in Analog mode, even when we attempt to overwrite it. Notably, the oth...

Hi ST Community,I’m working with the STM32MP135D-FK (Boyard) board and trying to build a Weston image using a custom machine configuration, following this official guide::link:https://wiki.stmicroelectronics.cn/stm32mpu/wiki/How_to_create_your_own_ma...
Hi all.I am confused about how I am supposed to provide power to the STM32MP257F-DK as it seems I am not providing enough power to the board when connecting the board to my PC via the STLINK/Power connector as the red Power LED is on and the Green LE...
The board seems to be very selective on the power provided on the STLINK port. Even with an USB 2.0 external powered hub, it often does not power on. The board seems to need 5V/3A. That would mean a USB C Hub, (USB 3.0 Type A max is 0.9A) or using...
Hi,And currently using the STM32MP157F-DK2 demonstration board using Open ST Linux (Kirkstone).And have an issue with the audio codec CS42L51 in that on startup the codec operates as expected, once any playback occurs, 4 seconds after playback stops ...
