TMS320F28388D: Example to Transfer the SPI Read Data to a Memory with DMA without Interrupt nor CPU Interaction?

Part Number: TMS320F28388D

Hi all!

I want do some bulk data read with SPI and to write it to a memory with DMA without CPU interaction. For example, I wanna read 4K words. Let say each burst 8words then it makes 512 transfer. I wanna start the DMA or DMA's at the beggining of the code and wanna get inerrupt when all transfer is done and written to a memory. And I want to do it continuously not once. The next bulk will be overwritten to make polling.

What I have seen that spi_ex5_loopback_dma is the most closest example for my purpose but not the same. Can I edit this example for my purpose? If yes how? Or does anybody has an example that might help me? Any kind of help would be appreciated.

cheers,
