Hi , I had worked with MMP2 platform several weeks. The mmc/sdio interface have constraint about transfer size. The transfer size must be 8-byte alignment. If any transfer size is 4 byte alignment and not 8-byte alignment. This peripheral ip can't support(miss dma end interrupt or bad transmission) even DMA mode or PIO mode.
