6657 edma spi

Hi,

 I am trying to use the edma3 functions to map a spi tx and a spi recv dma.  I call edma3init() for each hdma handle.  I then try to request channel by calling EDMA3_DRV_request_channel().  I set TCC and CH1 to EDMA3_DRV_HW_CHANNEL_EVENT_30 for the tx and EDMA3_DRV_HW_CHANNEL_EVENT_31 for the receive.  WHen calling the request channel, I do not get the EDMA3_DRV_SOK value back.  What am I doing wrong
