Experience showed that it's a good way to start barebox from U-Boot as a second stage loader and add the low level init stuff later.This way you should be running up quite fast. Feel free to ask further questions about it. > > The USB worries me, since I am just familiar enough with it to know how > complex it can be. Time will tell What kind of controller does this SoC have, EHCI, OHCI?
