Host to DSP Interrupt through PCI for DM642 EVM Problem

Started by Unknown May 26, 2004
Hi,

I am using TI provided PCI driver for DM642 EVM card, I was able to
download my code correctly, and successfully have my code running
after writing 1 to DSPINT in HDCR.

I am trying to cause an interrupt for host to DSP after the code is
running. I set the HOSTSW bit in PCIIEN and writing 1 to DSPINT in
HDCR, and set up my ISR for INT13. However, I could not get any
interrupt by doing so. What am I missing?

Thanks in advance!

Linda




Hi,

I'm not using DM642 EVM, but we have a C64x system here.
Did you enable the Int13 and the NMIE in the IER register ? How about
the GIE in CSR register ?

Regards,
BehCS
