【OpenBMC】直接加载应用到QEMU

1、修改指定文件

vi workspace/sources/phosphor-state-manager/bmc_state_manager_main.cpp

2、编译修改的仓库

bitbake phosphor-state-manager

编译后的二进制文件：./workspace/sources/phosphor-state-manager/oe-workdir/package/usr/bin/phosphor-bmc-state-manager

3、创建一个安全文件系统

mkdir -p /tmp/persist/usr
mkdir -p /tmp/persist/work/usr
mount -t overlay -o lowerdir=/usr,upperdir=/tmp/persist/usr,workdir=/tmp/persist/work/usr overlay /usr

4、将编译好的文件传输到指定目录下

scp -P 2222 ./workspace/sources/phosphor-state-manager/oe-workdir/package/usr/bin/phosphor-bmc-state-manager root@127.0.0.1:/usr/bin/
