I'm using OpenWRT on a device with tiny 8MB Flash (HLK-RM04), there are many officially preapared images, released by OpenWRT such like links below.
In compare with my own built images they have way lower size.
For example they have LuCI and tons of other packages which I omit from my own kernel configurations, yet my image size will become ~4MB and those images with more packages are near 3.5MB approximately.
I was wondering if there is a configuration to compress this much or not?!
