I have a question about the ECM Module of TMS320DM64x+ DSP:
If I want to route EVT0 to HWI, would I must configure the DSP/BIOS in static, and the interrupt selection number is the number of ECM's group? Could I set the interrupt selection number more than 3.
I don't think you have to configure this statically. There should be some runtime API's that let you set this up at runtime if that is what you are asking.
You cannot set the interrupt selection number to be greater than 3. It should one of the following numbers: 0, 1, 2, 3. Only these are from the event combiner.
