This document is intended to provide a set of recipes for common OpenBMC customisation tasks, without having to know the full yocto build process.
The kernel recipe is in:
meta-phosphor/common/recipes-kernel/linux/linux-obmc_4.2.bb
To use a local git tree, change the SRC_URI to a git:// URL without a hostname. For example:
SRC_URI = "git:///home/jk/devel/linux;protocol=git;branch=${KBRANCH}"
The SRCREV variable can be used to set an explicit git commit. The default (${AUTOREV}) will use the latest commit in KBRANCH.
The Palmetto target is palmetto.
If you are starting from scratch without a build/conf directory you can just:
$ cd openbmc $ TEMPLATECONF=meta-openbmc-machines/meta-openpower/meta-ibm/meta-palmetto/conf . oe-init-build-env $ bitbake obmc-phosphor-image
You can reconfigure your build by removing the build/conf dir:
rm -rf build/conf
and running oe-init-build-env again (possibly with TEMPLATE_CONF set).
