STM32MP2 does not have USB OTG - SD card is the only option then?

DMårt · ‎2025-06-07

At STM32MP1, there is an USB OTG, were you can flash the eMMC via the USB OTG.

But in STM32MP2, there is no USB OTG. Does this mean that I need to flash my SD-card instead? Just like Raspberry Pi etc.?

Or am I supposed to flash the eMMC via the USB C connector?

HI @DMårt

in STM32MP2, USB3DR IP is the equivalent of OTG seen on STM32MP1.

You flashload using USB type-C or USB micro-B in same way.
