I am examining NAND flash content.
I used mfg-tool to update the NAND flash.
When I dumped the first 1MB of flash of U-Boot partition (see attachment Mtd0_1MB_no_oob_20190418.bin) the contents of FCB appears to be garbage. It does not match up with documentation Table 6-37 i.MX 7Dual Applications Processor Reference Manual, Rev. 1, 01/2018
I tried using "kobs-ng dump -v"
The response is incorrect NCB structure.
I am attaching mfg-tool update log.
There appears to be no error messages during firmware upgrade.
Is there anything I can do to fix this?
The board boots up fine, just the incorrect NBC/FBC is worrisome.
