Hello everyone! I've got a C64x problem :) I'm using the DM642 evaluation module as a PCI device in a PC running Linux. I'm trying to generate an INT from the DSP to the host CPU, without any success so far. - I'm not using the JTAG interface - The DSP is in PCI boot mode, held in reset until the CPU host generates an interrupt. [this is working] - My code (dsp-side) boots. It initializes EMIF, etc. and then shoulg generate a dsp to host interrupt by asserting INTREQ in RSTSRC. [this is not working] Am I missing something? I would appreciate any help: code, tips welcome! Thanks!
