Dear
I’m developing a home automation application with Beaglebone, for it I need to work with UART’s pins and It happens a strange problem.
I tried to work with UART’s using two ways, through USB host and UART2 both I can’t read what I’m receiving. I can only read through a minicom ternimal. I researched all websites as possible as could but without success. I didn’t find any serial library for arm - gcc neither.
For example,
For transmit a data I type : echo " teste" > /dev/ttyO2 or /dev/ttyUSB0 , It works
but for received;
cat /dev/ttyO2 or cat /dev/ttyUSB0
Nothing happens
For you understand better, follow my Youtube Video

Can anybody help me with this situation.
Best regard’s
Mauricio.
