I tested from 22.3.0 and stopped at 23.05.0 - no errors found.
However, 2.4 GHz WiFi does not work correctly, the speed reaches only 20 Mbps at best.
In versions 24.10.0 - 24.10.1 - SNAPSHOT, the problem persists.
Could you help me figure out the cause?
Also, after the first failed installation of the Breed bootloader, all MAC addresses and everything else except the serial number were erased. I suspect this may be related to OpenWrt, but I'm not entirely sure.

Sorry for the mistakes, I wrote with artificial intelligence and a translator
By the way, I read the forum and I notice this error in many logs

this is what it looks like without the error
the error starts appearing on 23.05.5
Nothing (extra) to worry about.
It did not suddenly get worse, just started to tell how bad it was from the start.
nand driver reads chip manufacturer bits but maintains ecc proportion from OEM. I
thanks for the answer
I just tried to solve this problem myself with artificial intelligence
he said that this error can speed up degradation
so I started to worry
