Sorry, i have low skills on programing. I'm about 1 day reading all the related content on Github and trying to do it right but no success yet. Try it again with nand write comands but still no successErr.. you've loaded `uImage` to memory (RAM) at 0x80008000.
Then you've overwritten that (in RAM) with `uImage_recovery`.
And then you tried to load and boot kernel from the NAND (which you did not modified at all).
You seem to be missing NAND write commands.
