Hi,
I tried to install 15.05 on a TP-link 3040v2, and even though it works, I could for the life of me figure out how to clear up enough space so that I could mount a USB thumb drive to overlay. However, I downloaded and installed the older image (14.07), which leaves enough space to mount the USB drive, and then extroot / overlay was easy. I'm happy to get it to work at all, but concerned about using an older version of the OpenWRT distort.
The questions I have are:
1) Is there a way to get a smaller 15.05 (or future) image? I'm thinking it'd be really useful to have a minimal image, that does come with USB/ext4 kmod's, but perhaps not all the other bells and whistles?
2) Is there any way to upgrade my 14.07 to 15.05? I suspect the answer here is "nope", but figured I'd ask anyways.
Cheers,
