Dear developers, hello!
My cmcc rax3000m SPI nand has a factory date of 20240215. When installing openwrt24.10.4 according to the official installation method, the prompt when writing BL2 is as follows:

root@RAX3000M:~# cat /proc/mtd

What is the id of flash chip?

dmesg | grep -i spi
3

Install and load kmod-mtd-rw?

4

dmesg | grep -i spi

Running this command produces no output.

releases/21.02-SNAPSHOT/targets/mediatek/mt7981

CMCC customized version 21.02, the official does not support this goal, and the software package cannot be installed.

in that case, use serial to boot the initramfs, run the NAND install that way.
obviously step 5 becomes step 0, and step 6 isn't needed any more.
