When you write the bin file with u-boot you use nand write.jffs2 <bin-file>. Whatever that produces is good for u-boot to load into ram for execution but when you try to mount that block in Linux, you get a bunch of problems. In other words, they don't appear to be compatible. I'm thinking that somehow I need the kernel image already in some sort of JFFS2 image format and do what you said and just write it to /dev/mtdblock4.

If the MTD partition holding the kernel is formatted as jffs2 then you should be able to just mount and then copy across the new kernel image. If it's a raw partition then I think you can just do 'cp ImageFile /dev/mtdx' Regards, Stuart On 31/08/11 18:38, Chris Westervelt wrote: Has anyone worked out a mechanism that would allow one to re-write the Kernel MTD block with a fresh Kernel from inside linux? If I try to mount this partition jffs2, I get lots of errors and an inevitable mount failure. Chris Westervelt
