The MMCI driver requires that all transfers be a multiple of 1 << blksz_bits. So, if you want to transfer (eg) 9 bytes, it must be transferred as 9 one byte blocks. So set blksz_bits to 0 and blocks to 9. -- Russell King Linux kernel 2.6 ARM Linux - http://www.arm.linux.org.uk/ maintainer of: 2.6 Serial core
