We are using Micron MT29F2G08ABAEAWP Nand flash in place of the original Samsung K9LAG08U0M-PCB0. When I tried with ATK tool V1.71 to load the Uboot, uImage, rootfs.jffs2 files on to the new flash with 3 stack configuration of PDK, I am facing error when I try to erase the flash. The error message is attached. I don't know, is there any specific procedure / setting to be maintained for changing the flash. Kindly help me resolving this issue and loading the images to the new flash.
