Ali, I hope we discussed about this already right ? http://e2e.ti.com/support/embedded/linux/f/354/t/368940#pi239031349=1 Still are you facing any problem. Able to see any signal transitions on that GPIO which is configured as CS ? We can use GPIO as CS directly for SPI device. This patch is required if you are using latest kernel version which could support DTS. http://docs.blackfin.uclinux.org/doku.php?id=spi
