IIRC the onboard firmware actually uses the micro SD for UART. > Not having an uart also means that I cannot get the board into > FEL mode (I do have a usb A <-> A cable). > > I wonder if my board has a broken uart, or if the system > image uses a different uart by default ? > > Have you tried booting with u-boot written to sdcard with > this patch-set ? Does this work, and does the SPL header > get printend on the bottom right uart connector ? It's actually the bottom left. Not sure why the wiki page is wrong. Anyway, I didn't get any output either. I haven't gone into finding the problem though, and won't be able to until next week.
