Contents

This repo currently contains the following directories

• Code common to all platforms under the common directory.
• Platform specific code in the meta-facebook directory.
• The ASPEED OpenBIC SDK under the src directory.
  • app - An example application to test the various drivers
  • arch - Supporting files for the board architecture (ARM) and CMSIS.
  • board - Definitions for the various supported boards.
  • configs - configuration files used for building the supported board types
  • Drivers - Currently implemented drivers.
  • libraries - Supporting libraries such as getopt and FreeRTOS+
  • os - Supported RTOSs (currently only FreeRTOS)
  • toolchain - The included cross compilation toolchain used to build OpenBIC
  • tools - Misc tools

Currently supported RTOS

OpenBIC functionality is written using the CMSIS RTOS API as an RTOS wrapper. This allows for RTOS agnostic design and feature implementations.

The currently supported RTOSs are:

• FreeRTOS

Currently supported Boards

The board configuration files can be found in the configs/ directory.

The currently supported boards are:

• ASPEED AST2600 EVB
• ASPEED AST1030 EVB

Build Instructions

Dependencies

Tool	Version
GNU make	v4.1 or later
Python	v2.7

The cross compilation tool chain is currently packaged with the SDK:
toolchain/gcc-arm-none-eabi-9-2019-q4-major

Build Steps

The first time the repo is cloned the submodules will need to be initialized.

1. run git submodule init

2. run git submodule update

3. Navigate to the src Directory:
   cd src

4. Source the enviroment file:
   source setenv.sh

5. (OPTIONAL) Change configurations through kconfig:
   make menuconfig

6. Return to the top level directory:
   cd ..

7. Call make for the desired platform:
   make yv35_cl

The build ouput can be found in the bin directory.
