I have a DVR with corrupted Kernel. Getting the recovery files to the manufacturer. By U-boot update command I'm not getting the correct kernel. By SDK recording program HI-3531 chip can replace the U-boot for another version more when I try to do with the kernel displays the following error Invalid nand flash block size! Someone forum would know what generates this error and how to fix it?
