🧩 AllwinnerTech T507 Android BSP Build Guide

This post explains how to build the Android BSP for AllwinnerTech (AW) T507.
Most BSPs distributed by Allwinner follow a very similar structure,
so the same process can generally be used for other SoCs as well
(except for SoC- or board-specific configurations).

---

🧰 Recommended Build Environment

• Operating System: Ubuntu 16.04 (officially recommended by AW)
• SDK Folder Structure:
  • android/ → Android framework and AOSP sources
  • longan/ → U-Boot, kernel, device tree, and related build scripts

---

⚙️ 0. Install Required Packages

Run the following commands to install all dependencies needed for the build.

$ sudo apt-get install git-core gnupg flex bison gperf build-essential \
zip curl zlib1g-dev gcc-multilib g++-multilib libc6-dev-i386 \
lib32ncurses5-dev x11proto-core-dev libx11-dev lib32z-dev ccache \
libgl1-mesa-dev libxml2-utils xsltproc unzip

$ sudo apt-get install u-boot-tools

 

---

🚀 1. Build U-Boot

(Option 1) Using build.sh

 

$ cd longan/brandy/brandy-2.0
$ ./build.sh -p sun50iw9p1

(Option 2) Manual Build

 

$ cd longan/brandy/brandy-2.0/u-boot-2018
$ make distclean && make sun50iw9p1_config && make -j32

---

🧩 2. Build the Kernel

Run the configuration script to set the platform and board type.

 

$ cd longan
$ ./build.sh config

Example Configuration Steps

Welcome to mkscript setup progress
All available platform:
  0. android
  1. linux
Choice [android]: 0

All available ic:
  t507
Choice [t507]: 0

All available board:
  0. demo
  ...
Choice [demo]: 0

After configuration, build the kernel:

 

$ ./build.sh

---

📱 3. Build Android

 

$ cd android
$ source build/envsetup.sh
$ lunch

You’ll see a list of available build targets.
Choose the one matching your kernel board configuration, for example:

 

33. mercury_demo-user
34. mercury_demo-userdebug

Select 34 (mercury_demo-userdebug).

 

$ extract-bsp
$ make installclean   # Run only once
$ make -j8

---

📦 4. Package the Final Image (pack)

After building, package the OS into a single .img file using the pack tool.
The available options control debug output and secure boot settings.

$ pack          # Debug messages output via UART0
$ pack -d       # Debug messages output via CARD0
$ pack -v       # Enable security (signed image)
$ pack -d -v    # Security enabled + CARD0 debug output

 

💡 If secure boot isn’t required, a simple pack command is sufficient.

---

🔐 Security Image Packaging

If you’re building a secure image, you must generate encryption keys first:

 

$ cd longan/build
$ ./createkeys

Without generating keys, pack will fail with a security-related error.

---

✅ Build Complete

Once packaging is finished, you’ll get the final firmware image:

 

t507_android10_demo_uart0.img

You can now flash this image onto your board and boot it successfully 🎉
