openbmc's Introduction

OpenBMC

Build Status

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.

Setting up your OpenBMC project

1) Prerequisite

  • 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"

2) Download the source

git clone https://github.com/Nuvoton-Israel/openbmc.git
cd openbmc

3) Target your hardware

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

4) Build

. openbmc-env
bitbake obmc-phosphor-image

Additional details can be found in the docs repository.

5) build images

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:

  1. image-bmc - The entire 32MB image including BootBlock, u-boot, linux kernel and file system, can be programmed into the beginning of flash
  2. image-u-boot - Includes only BootBlock and u-boot and their headers can be programmed into the beginning of flash
  3. image-kernel - FIT image that includes linux kernel, device tree and an initial file system, can be loaded to the linux area in flash
  4. image-rofs - Main (and large) OpenBMC file system, can be loaded to the rofs area in flash

Note

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

6) Programming the images

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.

7) OpenBMC user login

after the OpenBMC boot please enter the following login and password:

Phosphor OpenBMC (Phosphor OpenBMC Project Reference Distro) 0.1.0 evb-npcm750 ttyS0

evb-npcm750 login: root
Password: 0penBmc (first letter zero and not capital o)

8) More information

For more info follow the readme.txt in: ftp://ftp.nuvoton.co.il/outgoing/Eval_Board at the section: "Loading to Evaluation Board and running instructions". In order to get a password for the ftp please contact [email protected]

9) Enabled features

For more info of openbmc features we enabled in: https://github.com/Nuvoton-Israel/openbmc/tree/master/meta-evb/meta-evb-nuvoton/meta-evb-npcm750
