next in thread | raw e-mail | index | archive | help
While regression testing my patches, I found that USB is not working on the AT91RM9200 from head (pre-patch). Error shown are the same with or without a USB device attached. Just wondering of anyone has any insights before I spend time going down this rabbit hole... KB920x >go 0x200000e0 ## Starting application at 0x200000E0 ...
