We are trying to get RS485 working on the evaluation board 3.2A but it doesnt send or receive anything.
On the evaluation board, the upper RS232 port is disabled by closing JP16. JP13 and JP15 are open for full duplex configuration and UART-B is connected to the PC using a USB to RS485 adapter.
RS485 is enabled in the application using ioctl TIOCSRS485 and the data is being sent to /dev/ttymxc1.
Are we missing something? Thanks in advance.
