OpenWRT for Arduino YUN - Rev 2

For Developers
1

Hello Everyone,

I had an rev-1 board of Arduino YUN, i built OpenWRT for it, the size of the OpenWRT binary was about 16M

Now i buy a rev-2 board of Arduino YUN, I build OpenWRT for it, the size of the OpenWRT bin is only 5.4M

The repository i used to build is github.com/openwrt/openwrt

Is the size correct? How can it be only 5.4M? The file name of the build is

openwrt-ath79-generic-arduino_yun-squashfs-sysupgrade.bin

Im just trying to verify so i dont brick my board with it.

Thanks
