Thanks, I think I have all the previous ones that where pushed to the linux-sh list. If there's a git tree I could pull from that would make our job easier. We have got SDHI0 and SDHI2 working with device tree, but we're currently seeing less than a megabyte a second when direcly dd-ing blocks from the card. Is this a noted issue? We got ~11MiB without DMA on the 3.4-ltsi series. As a note, I will be away from the 20th December untill Janurary 6th and it is likely the rest of the team here will be away from 21st. -- Ben Dooks http://www.codethink.co.uk/ Senior Engineer Codethink - Providing Genius
