AM625: Boot SPL from USB storage

Ethan Park

Part Number: AM625

Tool/software:

I want AM62x board to boot from USB storage.

Processor SDK Linux for AM62x says that the boot SPL from USB storage documentation is pending and should be asked to Help e2e. (https://software-dl.ti.com/processor-sdk-linux/esd/AM62X/latest/exports/docs/linux/Foundational_Components/U-Boot/UG-Memory-K3.html# 3.1.1.4.2.2)

How can I enable SPL boot from USB storage?

I want to know how to partition USB mass storage and what binaries to put in partitions.

Hi Ethan,

If you familiar with the SD card partitioning and binary layout in SD card boot mode, the USB mass storage in USB host boot mode is the same as the SD card.

The only difference is that the U-Boot binaries on the boot partition should be compiled with the patch in the link below to set USB0 port to host mode.
