RTOS/AM3352: How do I set the source address when DMA reads GPMC data

Part Number:AM3352

Tool/software: TI-RTOS

Hi

    Refer to the example of EDMA, I have been able to complete the EDMA data transfer from RAM to RAM,

my GPMC driver is also able to work, when I want to use EDMA to read GPMC data,

how to set the source address in the EDMA parameter, is the base address of GPMC 0x50000000?I

tried, set this to not read GPMC data.

BR!
