I have connected oscilloscope to RTS/CTS/RX/TX pins and nothing happens when i try writing to the ttymxc1 port, they just stay in 'high' state. However any attempt to write to it (echo -ne 'ASDFG' > /dev/ttymxc1) doesn't result in anything. When i boot i see the serial driver registers the ttymxc1 port. I have configured the UART2 in the device tree as follows: (I need to make this output default console output)
On the board we also have UART2 connected to MAX3232 UART to RS232 transceiver, and RS232 connects to the lap top USB.
We have a direct UART to USB connection for UART1 debug output which works fine. We are using im圆 Dual Lite with kernel 4.1.15, with custom yocto meta layer and on a custom board, that was prototyped from the im圆 wandboard.
