I've uploaded the code here if anyone wants to tinker with it. It's hard without owning the device to troubleshoot the nand ecc issues you're seeing:

Recently I saw that the Xiaomi ax 6000 has started to support openwrt, the Xiaomi Mi 6000 and the Redmi ax 5400, The two machines are homologous, and most of the chips are the same. The change is the loss of a set of aiot antennas and a 2.5g port, I tried to brush the ax 6000 openwrt firmware into the Redmi ax 5400, and he still had problems with the Flash ecc drive，and the LAN port seems to be not accessible，i think it's switch chip driver problem[ 2.124265] UBI error: cannot open mtd rootfs_1, error -2 [ 2.124333] ubi0: attaching mtd19 [ 2.129373] ubi0 warning: ubi_io_read: error -74 (ECC error) while reading 64 bytes from PEB 0:0, read only 64 bytes, retry [ 2.132729] ubi0 warning: ubi_io_read: error -74 (ECC error) while reading 64 bytes from PEB 0:0, read only 64 bytes, retry [ 2.143536] ubi0 warning: ubi_io_read: error -74 (ECC error) while reading 64 bytes from PEB 0:0, read only 64 bytes, retry [ 2.154583] ubi0 error: ubi_io_read: error -74 (ECC error) while reading 64 bytes from PEB 0:0, read 64 bytes [ 2.165164] CPU: 1 UID: 0 PID: 1 Comm: swapper/0 Not tainted 6.12.34 #0
How is Immortalwrt related to this forum ?

I forgot to take a screenshot of the original openwrt, so I posted immortalwrt, which has very similar functions to openwrt. Immortalwrt is a branch of openwrt and is very popular in China. Both firmwares have the ECC problem of this flash memory.
The problem I encountered is exactly the same as yours. The flash memory cannot be started in ECC. It may also be a problem with the flash drive.
But I still haven't found the reason why it can't start? Theoretically, Xiaomi's ax6000 has no problem, so Redmi's ax5400 chips are the same, and even lack a 2.5g switch chip, so it shouldn't have any problems？
The screenshot above is from the initramfs version, right?
yes,it's initramfs
Have you found a solution? Same issue with a similar ipq5018 device - AX3000T V2.
Misread your question, @csharper2005
The first firmware has something wrong in the dts, with the second one Ethernet worked, and my problems are with the NAND ECC.
Not yet, sorry.
I bought a WSOP8 clip, but I have no time in the next few weeks to disassemble and reflash.
Will such support be applied to the "Gaming" edition as well? I think the router is almost the same https://wikidevi.wi-cat.ru/Xiaomi_Redmi_AX5400_Gaming_Router_(RB04) VS https://wikidevi.wi-cat.ru/Xiaomi_Redmi_AX5400_Router_(RA74)
There's a closed topic for it, also Adding OpenWrt support for Redmi AX5400 Gaming aka rb04 - #3 by newton-miku
anyone able to test these new builds for the Redmi AX3000 and AX5400?
I suspect 128 bytes oob size is not supported by the QPIC controller. Boot log would be much appreciated!
Hi, I'm interested in installing OpenWrt on my Redmi ax5400 (ra74). I have SSH access enabled. If you could tell me how to install this new version and how to obtain the boot log, I could install it and provide the necessary information.
Hello, are there any changes to this router? I could try it if you provide a test firmware.
