Other Parts Discussed in Thread: TMS320C6748

I use channel controller 0 of DMA on a C6748  to acquire and sends samples to a codec.

I wanted to use channel controller 1 to communicate with th host processor of my application by SPI. If  I use EDMA CC0 to handle SPI, it works. If I use EDMA CC1, it does not work. No events arrives in th channel controller. Are there some problems with EDMA CC1 ?

    Please refer to the datasheet for the TMS320C6748 in the section that describes the use of events with the two Channel Controllers, section 5.9.1.

    The SPI Rx and Tx events are connected to specific events in the table which are unique between the two Channel Controllers.
