OpenBouffalo Firmware Repository

This is a collection of Firmware/Example Applications for the Bouffalo Range of Chips utilizing the Bouffalo MCU SDK

Quick Start

For Pine64 OX64 Dev Board:

mkdir obfr && cd obfr
git clone https://github.com/XXX
git clone https://github.com/bouffalolab/bl_mcu_sdk.git
git clone git@gitee.com:bouffalolab/toolchain_gcc_t-head_linux.git
PATH=$PATH:<directory to toolchain_gcc_t-head_linux>/bin/
cd XXX/apps/helloworld
make

Then use BLDevCube to Flash the build/build_out/helloworld_m0.elf to your device

  • LowLoad
    • lowload firmware is used to assist Linux to boot on the BL808 Device. Please consult the OpenBouffalo Buildroot repo for more information

Configuring SDK Features

The Bouffalo SDK provides numerous configuration options, enabled via the proj.conf in a standard bl_mcu_sdk project. This repository has enabled menuconfig, to give a graphical interface to enable/disable features in the SDK. You can enter the configuration dialog by running make config in each applications directory.

Default Configuration Options for a application are saved in sdkconfig.default, and when a project is built, a sdkconfig is created (and may be edited by hand, or updated with make config). build/config/sdkconfig.h header file is also created when compiling, and any configuration options that affect cmake are placed into proj.conf

If a Application has a specific configuration options, a Kconfig file can be placed in the root of the application directory and it will be picked up automatically

If you wish to help out, updating the cmake/Kconfig with additional/new options or help text is greatly appreciated

Specifying Different CPU's or Cores

This SDK still respects the following commands to specify different CPU's/cores etc:

make  CHIP=chip_name  BOARD=board_name CPU_ID=d0

Please ensure you run make clean and remove the sdkconfig file if you change chips/boards or CPU's

Specify Location of the Bouffalo Labs MCU SDK

If your bl_mcu_sdk located in different path, then the following will work: BL_SDK_BASE=<path> make

Board Support

We have started to write a board support package for the Pine64 OX64 in bsp/ox64. This is WIP. Other Boards are welcome
