STM32MP157F-DK2: Boot from USB SSD Instead of SD Card

symeon · ‎2024-11-24

Hello everyone,

I would like to ask if it is possible to configure the STM32MP157F-DK2 to boot from a USB SSD instead of an SD card. If so, could you please share the steps or documentation?

Thank you in advance!

Best regards,
Symeon Zapsis

Hi @symeon

The STM32MP157F-DK2 always need to do low level boot from SD-Card (other boot interface such as Serial-NOR, Serial-NAND, eMMC or SLC-NAND are not available on this boarD).
The STM32MP1 does not have any way to boot from USB device such as external drive.

Only option is to put TF-A and uBoot on SD-card which will load the kernel from an USB drive.

I'm not expert and I don't know how this is easy or complex to do and if there is bootleneck (e.g. having USB host driver in uBoot).

Regards.
