Moved from the MCUs section - STM32MP157F is an MPU (as the title says!)Hello!I'm building battery powered device and considering STM32MP157F.Looking at the mainline upstream linux kernel(https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux...
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...
