I've got a big SPI transfer that I'd like to offload from the processor, but I am limited to 1024 elements when setting up the transfer.
As for solutions, I am thinking about looping small transfers, or using scatter gather. The uDMA limit is 1024 elements, and I need to transfer 6000 elements.
I see that a scatter gather mode is supported in the technical reference manual. Is scatter-gather the recommended uDMA workaround for transferring more than 1024 elements?
Is there an example of scatter gather in the lauchpads or SDK?
Thanks!
