Chained DMA transfer: SDRAM to internal memory

Hi,

 

currently I'm busy with the chained DMA transfers on a 21371.

Are there any examples how to use chained DMA transfers for reading SDRAM to internal memory?

I want to transfer 4 memory blocks from SDRAM to internal memory via DMA with as less as possible interaction of the DSP. Therefore, I thought I can use chained DMA but I'm currently not really sure who I have to set up the TCBs for it.

Any hint is welcome either in C or assembler.
