EVM6201, when my host program invoked evm6x_hpi_generate_int() to send HPI interrupt to DSP, in the DSP program the HPI interrup service function could not be triggered, but I could saw the DSPINT bit was set to 1. At the same time ,the CCS told me "Code Comoser could not locate: F:\PCIEnc2\Debug\intr_.asm Would you like to browse for it?" Why? How could my HPI ISR be triggered? My DSP program used DSP/BIOS. I suspeck the problem is because of DSP/BIOS.

Yours? Or a default system file? If yours, then everything is fine. If not, then it sounds to me like your DSPINT vector is pointing at code located in some other file or a default system file. -Jeff
