Hi,
I am working on RZ/G1H platform. I tested the UART with loopback by connecting RX and TX.
When I connect the Tx to Rx and write “testing” to the driver, I receive back something like the following:
# cat /dev/ttySC0 &
#echo testing > /dev/ttySC0
testing
testing
testing
......
If I remove the connection then only it stops printing.
I am getting more echo's than just the one I would expect, as well as a lot of whitespace. Why is this so? Shouldn’t the driver just print “testing” on the command line once?
What I need to change, in the driver ?
Attached the log for your reference.
