DRA72XEVM: Finding events IDs for the events->interrupts handling

Part Number: DRA72XEVM

Hello,

I'm adding interrupt handling for the C66x DSP. I've found the TMS320C66x DSP CorePac User Guide, which lists events and their IDs (Table 9-2). Unfortunately some of those events are specified as Available events. The situation is such that I need to know what some of those Available events mean. Note above says "See the device-specific data manual for more information about how these available events are used". I've tried to find those mapping in the AM572x Technical Reference Manual but I can't find what I'm looking for.

Could you point me in the right direction where I can find the remaining IDs of the events?

Regards, Michal

  • Take a look at the AM571x TRM, Table 17-3. DSP1_INTC Default Interrupt Mapping.  In that table, the left most column, IRQ Input Line, represents the 128 inputs to the 66x CorePac's interrupt controller.

    Thank you, that should be good enough for now.
