ARM9_STR91x_IAR RX interupt is not working

Posted by jhuber on December 5, 2007
I am trying to get serial working on ARM9_STR91X_IAR and am using the comtest.c example. The program is sending characters but it is not receiving characters. I put a loopback cable on the port and have watched the UARTx_RIS variable and it is never set. Has anybody noticed this problem? If so is there a fix for it?

Have you verified the loopback cable on say a PC to make sure it's configured properly?

Yes, I tested the cable and it worked on my pc.
