Dsp to Host interrupt

Started by Jean-Francois SIMON March 21, 2006
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!
