I'm using the sgdma with 32-bit aligned read buffers as recommended but I still get corrupted read data. I haven't found any known issues about 8-bit operation. Does anyone know if 8-bit operation works? It seems to work for many transfers but not all as if the starting address affects it.
Thanks

What interface are you transferring the data over?
I had terrible problems with holes in DMA'd data (from my dma engine) across the PCIe bus in Q 11.X with a memory mapped avalon interface.
Q12.0 fixed the problem (although the Q12.0 qsys component editor's badly broken so I'd recommend Q12.1 ).
