Hello,I have a custom board based on STM32MP151-C with an eMMC on the following pins:SDMMC2_CK PE3 (AF09)SDMMC2_D0 PE6 (AF07)SDMMC2_CMD PG6 (AF10)I read that the ROM expects the the SDMMC2_D0 pin on PB14 so I need to change it by using values from...

Hello,I need to flash a custom STM32MP1 board which only has JTAG (no USB port available). Additionally, I build the image using Yocto meaning the output are separate binaries (e.g. U-Boot) and .tsv files.The STM32CubeProgrammer detects the CPU with ...

Hi to both of you and thatnks for the answer. Yes, I made a typo with the SDMMC2_D0 pin (PC8 is coming from the example), so the first configuration is the one I need.@PatrickF We have the Rev.Z and the THGBMNG5D1LBAIL eMMC, so there shouldnt be a p...

Hi Patrick,we have changed the USB-UART Adapter and it should work soon. However, I am still wondering about the flashing. You mentioned we cannot flash over UART at the moment and we need some uBoot changes to avoid conflict with uBoot Console. Coul...

The wiring is okay, Ive checked it many times. I measured the data on the TX Pin (CN2 PIN 10 GPIO15), the 0x7F is detected, but no activity on the RX pin (CN2 PIN 8 GPIO14). Ill measure everything today again (with and without the pull-up) and write ...

Hi Patrick,I havent added a pull-up, Ill do it today and check the results. So basically the ROM cannot detect that USART3 TX is activated? And adding a pull-up on it could fix i?Regards
