I would like to use the J601 connector on the Expansion Board (described on page 26 in the HW User Manual for this Board).
I tested succesfull communication between UART1 and UART3 on J960 connector on the IGEP board.
So I wired my GPS Receiver to J601 and tried to catch the output with cat /dev/ttyS0, but there is no data available. The GPS is working and transmitting data on the TX Pin (also tried to switch TX and RX).
I had a look at the schematics of the Expansion Board. I think UART1_TXD_3V3 and UART1_RXD_3V3 are going to nowhere :shock:
Has anybody used this connector before?
