# Coreboot Buildroot
|
|
|
|
This repostory contains [buildroot](http://buildroot.uclibc.org/) configurations, patches, and addition meant to build a useful linux+busybox distribution which can be embedded on the eeprom of ThinkPad X220/X230 machines running [Coreboot](https://www.coreboot.org).
|
|
|
|
It includes three different configuration: the default config `coreboot_defconfig`, a minimal config `coreboot_minimal_defconfig` which can fit on the X230 without hardware modifications (but lacks some extra goodies), and a grsec configuration for both of these.
|
|
|
|
Some of the coreboot utility (ie: cbfstool, ifdtool, and nvramtool) packages are built from a local source. you will need to edit this path in `packages/coreboot/*/*.mk`
|
|
|
|
$ git clone https://github.com/xsmurf/coreboot_buildroot_project.git
|
|
$ export BR_PROJECT=$PWD/coreboot_buildroot_project
|
|
$ wget <buildroot-release.tgz>
|
|
$ tar -xjf <buildroot-release.tgz>
|
|
$ cd <buildroot-release>
|
|
$ make BR2_EXTERNAL=$BR_PROJECT coreboot_defconfig
|
|
$ make
|
|
|
|
After making changes in buildroot with `make menuconfig`, `make linux-menuconfig`, or `make busybox-menuconfig`, you use the included `$BR_PROJECT/scripts/save.sh` to export your changes back to the project.
