fmcjesdadc:A5gt, decreased destination bus width for DMAs to 256. Increased DMA FIFO to 32 

With lower buswidth, if all 4 channels are captured some samples are lost
With fifo size of 64, there are timing violations in the DMAC
With this configuration, 65536 samples could be captured from all 4 channels with no sample lost
Because of the DMAC destination bus is 256, the number of samples to be captured must be a multiple of 16, otherwise the system will freeze. This will be corrected in software
