Hello
I know this post is in the wrong forum, but I'm hoping I might get some answers here so I'm duplicating it here. The DM816x forum doesn't seem to get as much attention from TI as this one does...
We are porting a project from a TMS320DM644x Digital Media System-on-Chip (DMSoC) to a TMS320DM816x DaVinci Digital Media Processor.
The DSP in the early project is the C64x and the DSP in the new project is the C674x.
We were using a hardware interrupt for the DSP to inform the ARM when certain events take place. The register address being written was 0x01c40010. I have found documentation describing the purpose of this register:
http://www.ti.com/lit/ug/sprue15/sprue15.pdf page 17 says that the DSP can interrupt the ARM via two general interrupts
http://www.ti.com/lit/ug/sprue14c/sprue14c.pdf page 114 describes system control registers, where INTGEN is at address 0x01c40010.
I cannot find similar documentation for the DM816x.
How does the DSP interrupt the ARM on the DM816x? Where can I find documentation for this?
Thanks,
Annie.
