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 ?
