AP-303 disk space problem

Installing and Using OpenWrt
1

I followed the document to install the openwrt, after installing I find out only about 15MB is available for other apps. Is this how it suppose to be? Or are there other ways to expand it?
From the document it says that the Flash is 128NAND. Using fdisk and the u-boot env I think it's 32+32+64?
I guess I can put apps in tmpfs but it's less than ideal.

Openwrt doesn't allocate all available flash space, but leaves the original layout intact.

But when I install openwrt on rpi3 using a 16GB SDcard, it only uses about 256MB by default?

Even less, the default root partition size is ~100MB, but you can always resize it, and have it allocate the whole SD card.
