    Hi,

    Please explore the tty UART application, which you would find plenty online. You can do a loopback and check if you are receiving the same what you send in another port.

    Hi,

    You may use the attached serialcheck binary to test any uart instance or clone teh source form git://git.breakpoint.cc/bigeasy/serialcheck.git

    8371.serialcheck

    Refer to teh Readme.txt file for usage.

    For example to test UART10 (which is at /dev/ttyS9) you need to run teh following on the target,

    1. create a reference file, dd if=/dev/urandom of=binary count=1 bs=4096

     2. At the prompt start the receiving side first, serialcheck -d /dev/ttyS9 -b 115200 -f binary -m r -l 10

    3. connect to the target using telnet and run the transmitting side, serialcheck -d /dev/ttyS9 -b 115200 -f binary -m t -l 10

     

    Regards,
