Hi
In uDMA controller specification (pl230), Table 2-11It is mention that value of N should be multiple of four. But DMA will perform N+1 tranfer ex. if N=4 dma will perform 5 transfer. In scatter-gather mode dma uses primary data structue to configure alternate data structure, and number of transfer for primary should be multiple of four. So here value of N should be 3, 7, 11, 15, etc. and not multiple of four. Can anyone please confirm this behaviour ?
