Hi!
I have tried to find solution to get am335x based Silica/Pengwyn board booting from usb flash. U-boot on that board is based on u-boot 2013.10. I flashed it with similar configuration as mmc flash, but I did not find combination of configuration variables to get proper spl code generated. I studied codes and it seemed like am33x devices were left out from usb spl generation parts. Is there some kind of fundamental reason to prevent am335x devices not to boot from usb flash. If not, would anyone know the configuration combination for this set-up.
In fact, I found more than three years old patch that seems to make usb boot set-up for am335x devices: https://gitorious.org/rowboat/u-boot/commit/aaa9d5c083252218fd89afa68161f96b... However, it seems that these changed have somehow not been included in the mainline codes. Is there specific reason for this?
Best regards, Matti Kaasinen
