Hi, I am able to boot uboot. I can see uboot report No NAND device but suppose to be 2GB NAND device the Rev B boards? Why it is reporting or not detecting NAND device. I think because of that reason I am not able to store any environment variables. I am using uboot version: <<<<<<U-Boot 2013.04-dirty (Jul 10 2013 - 14:02:53) arm-angstrom-linux-gnueabi-gcc (Linaro GCC 4.7-2013.02-01) 4.7.3 20130205 (prerelease) GNU ld (GNU Binutils) 2.22>>>>>
This is new board barely 10 days used. If you can suggest or guide on this will be great help.
