Hi ,


I want to do loopback test for ucc uart in the p1025rbd board. I configured ucc3 and ucc7 for ucc_uart. In the ucc_uart.c code i am enabled "LOOPBACK" macro . Inserting the ucc_uart.ko module , two dev nodes where created ttyQE0 and ttyQE1 .


With user space application program im trying to write and read the data for loopback test. But it didnt worked. For loopback how the terimos is to be configured and  any sample code for read and write.
