SDK for Onyx Boox

The Onyx Boox SDK


The Onyx Boox SDK is used for developing applications on the Boox ebook readers produced by Onyx International.

Development environment

The toolchain used for cross-compiling can be obtained at This repository contains toolchains for various processors (platforms). Each directory is for one platform.


The directory imx31 is for BOOX A(X)60/A(X)60S, M90.


The directory marvell166e is for BOOX A(X)61/A(X)61S, BOOX M91/M91S.


The directory imx508 is for BOOX A62/A62S, M92/M92S and I62. The file gcc-4.4.4-glibc-2.11.1-multilib-1.0.tar.gz is the toolchain compiler.

Building the SDK

Grab the source: git clone git submodule update --init

Then download some prebuilt third-party libraries: In each directory in toolchain repository that mentioned above, there is an archive named with sdk_xxx.tar.gz. The archive contains the prebuilt third-party libraries for the target platform. Extract it to /opt too. Note: In /opt/onyx/arm/ directory, there can be only one platform at a time. If needed to build different platforms, rename the arm to different names, like arm_imx508, arm_imx31, arm_marvell. And link arm to the real directory by command: cd /opt/onyx/ && ln -s arm_imx508/ arm

If you want to build the third-party libraries from source, you can get the source code at

To build the SDK, install CMake and Rake, then run rake build:arm:default

CCache and DistCC will be used if they are available. If you do not want to use DistCC, append DISABLE_DISTCC=1 to the build command.

The SDK is frequently updated and sometimes may break compatibility with earlier versions. If you want your application to run no matter which version of the libraries are installed on the device, you can link your application against the static libraries. You can build the static libraries by running rake build:arm:static

Notes for 64-bit hosts

If you are running a 64-bit environment, please make sure you have 32-bit runtime libraries installed. (For example, on Arch Linux, it is multilib/lib32-gcc-libs.)
