TMS320C6457 GPINT0/1 channel issue

Other Parts Discussed in Thread: TMS320C6457
Hi Guys

Please help us TMS320C6457 for the following issue

We use GPINT0 and GPINT1 to trigger EDMA and can only use channel 0 for data transfer successfully. Using any other channels doesn't work. Any more setup do we need to do to make other EDMA channels work?

Thanks

    The settings you use for GPINT0 need to be changed so that you are using GPINT1. And the GPIO control registers need to be configured for GP[1] as they are for GP[0]. Any and all of the GPIO pins can be used as EDMA3 triggering events.
