Thank you Roman for the response. You stated exactly what I am seeing, it is only the rootfs file that fails while the uImage and etc.jffs2 files copy and write to nand with no problem. You will have to forgive my lack of knowledge on U-Boot since I have only been working on this specific task that involves U-Boot for about a week now so I have been on a steep learning curve. You mentioned U-Boot mainline not having this issue. Could you direct me to where I can find this so I can take a look? My concern is the cross-compiler that was created by a third party may not be compatible with newer versions of U-Boot and I would need to go through the patches to see if there was anything custom created. As you probably understand this is time consuming work, especially with the learning curve I am on. Again many thanks for the response!
