UART initialization in ADSP-21061

Started by amol gavande September 30, 2002
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.
