I have enabled UART2 on my Beaglebone Black using the device tree overlay
method. I am able to communicate with minicom but not in C. I used termios
to setup UART2, I have no issues writing data but I do when I try to read.
I don't understand why in minicom reading works and not in my C program.
What could be the reason?
ps- I've attached my code just in case.
I found out what I had wrong I was setting the new termios "newt" to zero.
I then used the previous contents of ttyO1 on newt instead. That worked
great, also I had to remove ICANON from the c_lflag to work.
