# OpenPOWER Firmware Build Environment

The OpenPOWER firmware build process uses Buildroot to create a toolchain and
build the various components of the PNOR firmware, including Hostboot, Skiboot,
OCC, Petitboot etc.

## Building an image

To build an image for a Blackbird system:

```
git clone --recursive https://github.com/open-power/op-build.git
cd op-build
./op-build blackbird_defconfig && ./op-build
```

There are also default configurations for other platforms in
`openpower/configs/`. Current POWER9 platforms include Witherspoon,
Boston (p9dsu), Romulus, and Zaius.

Buildroot/op-build supports both native and cross-compilation - it will
automatically download and build an appropriate toolchain as part of the build
process, so you don't need to worry about setting up a
cross-compiler. Cross-compiling from a x86-64 host is officially supported.

The machine your building on will need Python 2.7, GCC 6.2 (or later), and
a handful of other packages (see below).
