I have made a NAND-dump with flashcatusb from working router and programmed new NAND chip. CFE now booting fine.

but when image start booting I see loot of ECC errors like below:
Code:

[...]
Initalizing switch low level hardware.
Software Resetting Switch ... Done.
Waiting MAC port Rx/Tx to be enabled by hardware ...Done
Disable Switch All MAC port Rx/Tx
devinfo: block read

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