B4860QDS DMA shows Transfer Error. That's it

[mihaiciric]

I am using the netcomm ocn dma api to transfer using simple mode mem2mem. I am getting a Transfer Error, but no other information on the cause.

Is there any needed pamu/liodn changes that need to be taken cared off for simple mem2mem? The reference manual is extremely vague!

Thanks,

Mihai

I found the issue. Turns out I needed to use PAMU for mem2mem.

Thanks

Reference Manual states there is a number of number of possible reasons for transfer error - "non-correctable ECC errors on memory accesses, parity

errors on flash controller, address mapping errors, and so on". But, DMA controller itself does not offer more details, the only "Transfer Error" bit is available in SRn.
