Intractable initramfs recovery mode

Installing and Using OpenWrt
1

I've decided to learn openwrt using openwrt One.
Learning the terminology and the installation was going slowly but OK until I hit the wifi installation.

At that point, for no apparent reason, initramfs triggered, demanding a firmware upgrade.
Using luci I was unable to save the configuration, but decided to download the stable firmware version anyway.
The upgrade sequence proceeded without any error notification, but resulted only in the return of the initramfs mode, and no change to the firmware version.

The current parameters are:

root@OpenWrt:~# ubus call system board
{
        "kernel": "6.6.57",
        "hostname": "OpenWrt",
        "system": "ARMv8 Processor rev 4",
        "model": "OpenWrt One",
        "board_name": "openwrt,one",
        "rootfs_type": "initramfs",
        "release": {
                "distribution": "OpenWrt",
                "version": "SNAPSHOT",
                "description": "OpenWrt SNAPSHOT",
                "revision": "r27876+1-3098b4bf07",
                "target": "mediatek/filogic",
                "builddate": "1729584976"
        }
}

I was attempting to install the sysupgrade version of 24.10.4 (r28959-29397011cc)

Any thoughts on how to proceed would be most appreciated.

Thanks

You've got serial, post the flash sequence, and boot log of the failing boot.

Make sure that the fitblk package is installed. Some older versions did not include it in the image, and that causes sysupgrade to just fail silently and not perform an upgrade...

$ opkg list-installed fitblk
fitblk - 2

Thanks, that's a really useful technique, which I had no idea about
As it turned out, in the course of a couple more attempts using a serial cable and Screen, the 24.10.4 upgrade worked.

Cheers
