I have an STM32MP1 that are connected to an eMMC (Embedded Multi Media Card). My goal is to flash the eMMC with a Linux .img, built from Buildroot. The eMMC has the same pin configuration as a regular SD-card, which is very important to understand that eMMC and SD-card speaking the same protocol over the same communication bus.
But using .img file with STM32CubeProgrammer is not going to work, because STM32CubeProgrammer wants .tvs files instead of .img files.
So there must be another way I can flash the eMMC, though the STM32MP1 processor, via the USB OTG?
I mean. How else should you use .img files?
Try balena etcher to copy your image on the sd card. After successful eMMC/SD card writing, remove the sd card, put it in board and power the board.
