Having doing a workshop regarding OpenST linux boot customisation (https://www.youtube.com/watch?v=hqGA5Krk0mU), I stumbled on a problem with a mass storage mount. Doing "ums 0 mmc 0" in uboot gives me partitions within an sdcard but only to see them...
Hello, I am using the STM32MP157F-DK2 board, I also developed a carrier board in order to use external peripherals. I am using a 5V external power supply and I supply it through pin headers CN2 expansion, since I don't want to use the USB type C conn...
Hi Im using a STM32MP157-DK2 with a OpenSTlinux. I load my .elf file of for the M4 to /lib/firmware/ and starts it by chaning the state to start in remoteproc. The problem I have is that remoteproc seems to not run the code from the beginning of the ...
Hi there,I have a custom board based on STM32MP157F, with USB2 connected to STM32CubeProgrammer for flashing the eMMC. No USB-ID, no USB-VBUS connected.The STM32CubeProgrammer downloads the FSBL and U-Boot, but the software does not reconnect as "USB...
