after days research, i found the offical pcduino3 image is NOT adapted to pcduino3 nano. the network device of nano is Realtek RTL8211E which is not supported by the image.

so you can't use this image if you are using a nano version of pcduino3 http://downloads.openwrt.org/releases/19.07.5/targets/sunxi/cortexa7/openwrt-19.07.5-sunxi-cortexa7-sun7i-a20-pcduino3-squashfs-sdcard.img.gz

however, pcduino3 nano are supported by upstream very good, i have successfully brought it up with some changes. It's easy to build a pcduino3 nano specific image, i will paste the patch here later.
