    Hi,
    I already purchase 5 UDOO board. I writing the code on arduino part to read the RFID card using RFID reader through SPI port. The problem here is, only 3 board are working as expected, the rest of 2 board not working(cannot read RFID card). First i suspect the board is not-functioning. I try to upload another program(send data from arduino to linux) to that broken board, but its working. I dunno what the problem with the UDOO board. Any suggestion? thanks

    Hi mrar,
    can you check signals on the SPI bus? at first, better with an oscilloscope, just to see voltage levels.
