Can the Module boot from a bootable USB flash drive?
There are config bits for booting from the serial or USB ports too, but not from a USB thumb drive. The USB boot requires some tool that apparently TI hasn’t released. Serial boot is doable, but I haven’t had any need for it so far. The config pins determine the preferred boot sequence, and the SD BOOT switch affects one of those config pins.
@ mcalsyn - This is what I figured; possible but not not released or something.
