Android Build and Flashing

Product name

Use the following product/board name inside the source tree:

i527bv3

The archive or repository may still be named x527_android13 or contain t527; select i527bv3 in the released SDK build instructions.

Source package

tar -xzvf x527_android13.tar.gz
cd x527_android13
tar -xzvf ../prebuilts.tar.gz
tar -xzvf ../external.tar.gz

Read the SDK readme.txt, load the build environment, choose i527bv3, and build as a normal user. Images are normally placed under longan/out/.

If required:

sudo apt update
sudo apt install libelf-dev

PhoenixSuit flashing

Connect the Type-C OTG port, load the full image in PhoenixSuit, power the board off, hold FEL and power on or press RESET. Wait for flashing to complete before reconnecting power.

TF-card update

Use PhoenixCard to create an update card. This operation overwrites the TF card. Insert it while power is off, boot the board, wait for completion, remove the card and reboot.
