The OpenBMC project can be described as a Linux distribution for embedded devices that have a BMC; typically, but not limited to, things like servers, top of rack switches or RAID appliances. The OpenBMC stack uses technologies such as Yocto, OpenEmbedded, systemd, and D-Bus to allow easy customization for your server platform.
- Ubuntu 14.04
sudo apt-get install -y git build-essential libsdl1.2-dev texinfo gawk chrpath diffstat
- Fedora 28
sudo dnf install -y git patch diffstat texinfo chrpath SDL-devel bitbake rpcgen
sudo dnf groupinstall "C Development Tools and Libraries"
git clone https://github.com/Nuvoton-Israel/openbmc.git
cd openbmc
Any build requires an environment variable known as TEMPLATECONF
to be set
to a hardware target.
You can see all of the known targets with
find meta-* -name local.conf.sample
. Choose the hardware target and
then move to the next step. Additional examples can be found in the
OpenBMC Cheatsheet
Machine | TEMPLATECONF |
---|---|
evb-npcm750 | meta-evb/meta-evb-nuvoton/meta-evb-npcm750/conf |
Palmetto | meta-ibm/meta-palmetto/conf |
Zaius | meta-ingrasys/meta-zaius/conf |
Witherspoon | meta-ibm/meta-witherspoon/conf |
Romulus | meta-ibm/meta-romulus/conf |
As an example target npcm750 evaluation board
export TEMPLATECONF=meta-evb/meta-evb-nuvoton/meta-evb-npcm750/conf
. openbmc-env
bitbake obmc-phosphor-image
Additional details can be found in the docs repository.
After building finished the built Images will found at: <OpenBMC_folder>/build/tmp/deploy/images/evb-npcm750 The relvant Images to use to upload the OpenBMC on the EVB are:
- image-bmc - The entire 32MB image including BootBlock, u-boot, linux kernel and file system, can be programmed into the beginning of flash
- image-u-boot - Includes only BootBlock and u-boot and their headers can be programmed into the beginning of flash
- image-kernel - FIT image that includes linux kernel, device tree and an initial file system, can be loaded to the linux area in flash
- image-rofs - Main (and large) OpenBMC file system, can be loaded to the rofs area in flash
All the files above are Image links to the latest build images, for copy the files to SD or USB storage device please make sure you copying the Images and not the links
For programming the OpenBMC to the EVB SPI flash go to: npcm7xx-poleg/evaluation-board See the readme.txt and follow the NPCM7xx_OpenBMC_Programming.pdf instructions.
