hi, i am writing a simple program in which i am initializing UART registers and one isr routine in which i am doing loopback. but the problem is that the processor is not generating the IRQ2 interrupt which is the UART interrupt. so it is not going in the isr routine. i am writing this program in C. plz solve my problem. |

Put an oscope on the IRQ2 signal and see if the UART is generating it. That should tell you if the problem is in the UART or in the SHARC. I've never used one of these kits so I can't help beyond that. [Please direct replies to the list.] |
