You have run out of space on your root.
Create a backup of your configuration, reset the device, try to reinstall packages one by one, restore your configuration. You can try to configure extroot with your SD card, then install packages you desire.

Remove some packages from the buildroot, configure extroot, after running extroot, install the desired packages.

but another device ,the rom is also 100%,13.5m,it works ok?the spi flash is the same ,
You have to have definitely free some nodes on SPI flash, I cannot remember how much exactly, but I would free at least 40kB in order to run the system. When you run out of SPI flash, how you are going to store your extroot configuration on SPI flash when you do not have any space there? Then you configure extroot for the SD card and after running extroot you can install the packages you removed from buildroot. After you will be happy with the system, you can backup the SD card and extroot configuration and you are done.
i build a small target,and configure the extroot at firstboot,then i install the mwan3,it happend,so ,i really don't know how to use it ,
root@OpenWrt:/tmp# opkg install mwan3_2.10.13-1_all.ipk
Installing mwan3 (2.10.13-1) to root...
Configuring mwan3.
