Image Burning

WalnutPi 2B Android uses the standard Android system. We have adapted the WalnutPi 2B hardware so that users can install various Android apps after burning this system image.

Open the Android folder; for image update notes, refer to the 说明文档.txt (Release Notes) inside. If Baidu Netdisk is too slow, you can also download from the QQ group files: 677173708

(After downloading, extract the compressed package to get the .img image file for later use)

A drive of about 100+ MB will appear in My Computer. This contains some configuration files for the WalnutPi Android system.

After burning, insert the SD card into WalnutPi 2B and power it on.

Burning to EMMC​
