openBMC开发1-环境搭建、编译

虚拟机：VMware

OS：Ubuntu22.04

一、环境安装

1：更新、安装需要的软件包：

sudo apt-get update
sudo apt-get upgrade
sudo apt install build-essential chrpath cpio debianutils diffstat file gawk gcc git iputils-ping libacl1 liblz4-tool locales python3 python3-git python3-jinja2 python3-pexpect python3-pip python3-subunit socat texinfo unzip wget xz-utils zstd
sudo apt install git librsvg2-bin locales make python3-saneyaml python3-sphinx-rtd-theme sphinx
sudo apt install fonts-freefont-otf latexmk tex-gyre texlive-fonts-extra texlive-fonts-recommended texlive-lang-all texlive-latex-extra texlive-latex-recommended texlive-xetex
sudo apt install git python3-distutils gcc g++ make file wget gawk diffstat bzip2 cpio chrpath zstd lz4 bzip2

2：检测当前语言环境：

locale --all-locales | grep en_US.utf8

 注：如果不是 en_US.utf8 ，执行如下命令切换

sudo dpkg-reconfigure locales

二、下载源码

openBMC OpenBMC · GitHub

git clone https://github.com/openbmc/openbmc

注：根据网络及设备状态，如出现错误，多尝试几次

三、编译

1：进入下载的源码目录

cd openbmc

 2：选择目标硬件

openbmc$. setup 
Target machine must be specified. Use one of:

openbmc$

 3：选择ast2600作为编译目标

openbmc$. setup evb-ast2600
Machine evb-ast2600 found in meta-evb/meta-evb-aspeed/meta-evb-ast2600
Common targets are:

     obmc-phosphor-image: Includes OpenBMC Phosphor userspace and Web UI

     core-image-minimal: A small image just capable of allowing a device to boot

     core-image-full-cmdline: A small image with more Linux functionality
                              installed, including a ssh server.

Note that the core targets will not set the default phosphor password.

evb-ast2600$

 4：使用bitbake命令开始编译

(过程会比较久，有报错则重新执行命令)

evb-ast2600$bitbake obmc-phosphor-image

 清理包缓存：

bitbake -c cleansstate ${PACKAGE}

5：编译完成

BMC固件生成位置： tmp/deploy/images/

evb-ast2600$ls tmp/deploy/images/evb-ast2600/*.mtd
tmp/deploy/images/evb-ast2600/obmc-phosphor-image-evb-ast2600-20241220010437.static.mtd
tmp/deploy/images/evb-ast2600/obmc-phosphor-image-evb-ast2600.static.mtd

四、QEMU运行固件

1：下载QEMU

wget https://jenkins.openbmc.org/job/latest-qemu-x86/lastSuccessfulBuild/artifact/qemu/build/qemu-system-arm

chmod u+x qemu-system-arm

 2：使用ast2600固件启动QEMU

登录用户名：root

登录密码：0penBmc （0 -> 是数字0）

QEMU$ ls
qemu-system-arm
QEMU$ ./qemu-system-arm -m 512 -M ast2600-evb -nographic -drive file=../openBMC/openbmc/build/evb-ast2600/tmp/deploy/images/evb-ast2600/obmc-phosphor-image-evb-ast2600.static.mtd,format=raw,if=mtd -net nic -net user,hostfwd=:127.0.0.1:2222-:22,hostfwd=:127.0.0.1:2443-:443,hostfwd=udp:127.0.0.1:2623-:623,hostname=qemu

注：结束QEMU命令：

ctrl+a，x (在QEMU下先按ctrl+a，再按x)

3：查看BMC功能

使用ipmi命令

ipmitool -H 127.0.0.1 -U root -P 0penBmc -I lanp -p 2623 -C 17 mc info

查看Web:

https://localhost:2443/login

ssh连接

ssh root@localhost -p 2222
