Hi, i fixed my mmc r/w issues. In PIO 4-bit mode the davinci mmc host driver passed all the mmc_test driver tests. But for some reason, in kernel 3.17, i still have issues when i "fsck" just after the mkfs. I still see errors. So i moved back to DMA 4-bit mode (DMA/TI EDMA engine enabled), as my board was working in kernel 3.5.1. In DMA mode, there was some conditions where the mmc access was blocking. This was due to the fact that the davinci mmc host driver was not able to get all the edma chan slots needed for the r/w operations. This because my board.c was reserving several chans / slots for the audio. I reduced those reservations, and all is fine.
