OpenBMC

OpenBMC is a Linux distribution for management controllers used in devices such as servers, top of rack switches or RAID appliances. It uses Yocto, OpenEmbedded, systemd, and D-Bus to allow easy customization for your platform.

Setting up your OpenBMC project

1) Prerequisite

See the Yocto documentation for the latest requirements

Ubuntu

sudo apt install git python3-distutils gcc g++ make file wget \
    gawk diffstat bzip2 cpio chrpath zstd lz4 bzip2

Fedora

sudo dnf install git python3 gcc g++ gawk which bzip2 chrpath cpio \
    hostname file diffutils diffstat lz4 wget zstd rpcgen patch

2) Download the source

git clone https://github.com/linux4sam/openbmc-mchp.git
cd openbmc-mchp

3) Target your hardware

Any build requires an environment set up according to your hardware target. There is a special script in the root of this repository that can be used to configure the environment as needed. The script is called setup and takes the name of your hardware target as an argument.

The script needs to be sourced while in the top directory of the OpenBMC repository clone, and, if run without arguments, will display the list of supported hardware targets, see the following example:

$ . setup <machine> [build_dir]
Target machine must be specified. Use one of:
...

Microchip supported machines are:

• sam9x60-curiosity-sd
• sam9x60ek-sd
• sam9x75-curiosity-sd
• sama5d27-som1-ek-sd
• sama5d27-wlsom1-ek-sd
• sama5d29-curiosity-sd
• sama7g5ek-sd

Other supported machines can be found under meta-phosphor/docs.

Once you know the target (e.g. sam9x75-curiosity-sd), source the setup script as follows:

. setup sam9x75-curiosity-sd

4) Build

bitbake obmc-phosphor-image

Additional details can be found in the docs repository.
