Derar all,
I am going through the example MCBSP_DigLpbkExampleProject that is stored under the following path \ti\pdk_C6657_1_1_2_6\packages\ti\drv\exampleProjects.
Particularly I try to understand the implementation of the the function registerEdma3Interrupts.
Regarding the current implementation the CIC0 for the core 0 and CIC20 for the core 1 are used.
These Chip Interrupts Controllers are mapped with the event 20 regarding the table 7.33, document tms320c6657.pdf.
In the configuration file there is the following definition
ECM.eventGroupHwiNum[0] = 7;
ECM.eventGroupHwiNum[1] = 8;
ECM.eventGroupHwiNum[2] = 9;
ECM.eventGroupHwiNum[3] = 10;
That means that the interrupt with id 7 should be mapped with the events from 0 -31. Is this right?
Why is the interrupt 8 enabled in this project?
Best regards
George
