Re-flashing NAND

[nikkaidmka]

I have made a NAND-dump with flashcatusb from working Linksys router and programmed new NAND chip. CFE booting fine. But when image start booting I see lot of ECC errors like below:

[...]

Software Resetting Switch ... Done.

any suggestions?
Thanks!

PS: probably have to set ECC settings on flashcatusb, but can't find right one

It's because you're on fresh NAND, and you haven't formatted the blocks...
