Hello all! Thanks for this wonderful piece of software.
I have WNR2000v1 and I successfully compiled my own images:
$ ls *_new.bin -l
-rw-r--r-- 1 root root 2228224 Mar 5 15:29 sqfs_new.bin
-rw-r--r-- 1 root root 1218787 Mar 5 15:30 uImage_new.bin
and flashed them however in bootup log I see:
[ 8.174614] mount_root: no usable overlay filesystem found, using tmpfs overlay
and thus I'm unable to save any settings.
I flashed earlier this images from https://www.tnhh.net/mobile/posts/lede-on-wnr2000v1-unsupported-hardware.html
(there is a link to his Google drive https://drive.google.com/drive/folders/0B8bRJIYStpVlZG13NEoyNGQ3a3M
$ ls *_works.bin -l
-rw-r--r-- 1 root root 2490368 Mar 3 14:50 sqfs_works.bin
-rw-r--r-- 1 root root 1256534 Mar 3 14:50 uImage_works.bin
so they are bigger then my images, but they works - I can save settings.
So what I did wrong with my images? Do I need to select something while in menuconfig?
I solved it. It turned out I just had to issue
jffs2reset command while in serial console and reboot the device. Afterwards it mounted overlay correctly and now the router remember settings through a reboot.
I managed to fit lede+luci on 4MB flash and I still have 100KB left.
