Hi
I'm trying to use ubi file system on Samsung NAND flash(K9F2G08U0B) of AM335X custom board.
when I flashed ubi image to Micron NAND(MT29F2G08ABA) on u-boot prompt, everything was fine.
After changing NAND flash to K9F2G08U0B on the same board, it shows the following message.
Could you give some hints?
The followings are commands and config to generate ubi image.
Thanks.
