Hi Joe, This board is based on a different SoC than the ODROID-C4. We'll need to add support for this SoC to the amlclock(4), amlreset(4), amplpinctrl(4) and amldwusb(4) drivers. Shouldn't be too difficult but it is a bit of work. If you're willing to test diffs with a relatively quick tunraround I can give it a go. Otherwise somebody would need to send me a board with that SoC. Cheers, Mark
