It looks like the detected spare size and ECC strength matches between the

Maybe you can try dumping the nand controller setup registers and compare

ich might be the misreporting.
In our driver, it comes out as:

size: 128
[ 16.107083] mt7621-nand 1e003000.nand: ECC strength adjusted to 12 bits
I tried adjusting in nand_on

The MX30LF1G28AD actually have 2K+128 flash layout, so i

This is the boot on the vendor legacy code - OpenWrt 18.06ish, with kernel
4.14.131, with probably a bunch of their customizations, but:
