DMA0_CONFIG register FLOW is set to 0x7 ( large model).if application enable ppi and don't running anyelse programme ,ppi_dam can work well.
if application enable ppi and go into while recycle .as follow ,the programme will crash soon
*pPPI_CONTROL |= PORT_EN;
the reasson may be caused by bus conflicts? The DMA traffic controller register DMA_TC_PER is set to 0x6F0
*pDMA_TC_PER = DMA_TRAFFIC_CONTROL_CONFIG_VAL; //0x6F0
*pEBIU_AMGCTL |= CDPRIO;//#define CDPRIO 0x0100
mdma_base_address_0 = MDMA_D0_NEXT_DESC_PTR;//0xFFC00E00
how to resolve the issue ? thanks.....
