I’m using ODYSSEY STM32MP157C development Kit, it has only two boot modes (eMMC and SDCard), I want to use USB Boot mode for fimrware flashing.

How to setup the USB boot mode for flashing firmware ?

We’re designing custom baseboard using ODYSSEY STM32MP157C SoM, I referred the STM32MP157C-DK2 dev kit from STM, they’re using USB_DP2 and USB_DM2 in USB Type C connector.

Here is the USB Type C schematics of STM32MP157C-DK2,

Can i follow the STM32MP157C-DK2 circuit with USB boot selection to support of USB Booting in my Custom Base Board?

Thanks,
