Hi Otavio,

OMAP4/3 can boot over the otg, so you can send MLO and let it wait for the second stage boot. We have already SPL USBETH in u-boot but in production otg flashing can be very useful. Think SPL as a differently configured U-BOOT doesn't change the problem but yes it's a nice idea.
But you'd usually want to have an 'upgrade mode' which allows DFU to run. In this case, this could be done using complete U-Boot instead of SPL, no? In case customer needs a slim version of it, it could be accomplished using a specific config and having:
SPL Update mode U-Boot (normal U-Boot with less features) Complete U-Boot (interactive and like)
or am I missing something?
Right, I agree completely with you.
That's the reason I do not understand why we have to push DFU into SPL. Maybe we both are missing something.
Best regards, Stefano
