Any particular reason you don't tried and use the current stable?

3

the device is pretty old has only 8 Mb flash

4

Removing packages with the image builder to reduce the size is not an option?

5

You can make a working configuration in v22, then sysupgrade to v23 and v24 removing all luci for example....

8 MB is enough. I am using a device with a bit less available flash on 24.10.

3 or 4 64kB blocks are consumed by OEM bootloader, unless you install something massive like 2 SSL frameworks you should be able to install few packages using firmware selector into squash fs.

Always check that resulting image is < 8MB-(4+6)64kB blocks to have writable config.
