Thanks, will check that again. I used the Flexcoms that are labeled on the
board itself (Flexcom 0, 3, and 4) and looked at the pinouts. I also used
the debug UART1 that works with U-Boot and Linux...
Not good enough. you also have to set the pin multiplexing in the
board.h header file. You have to match the physical pin with the logic
pin uses. Look at arch/arm/src/sama5/hardware/_sama5d2x_pinmap.h There
are multiple options for each logical pin mapping. You have to assure
the logical pin matches the physical pin used in the board schematic.
