鲁班猫修改终端图案
鲁班猫修改终端图案
这是鲁班猫原本在开机后终端打印的图案日志
我们可以修改根文件系统，改成我们自己的图案
拉取SDK源文件
可以看我“Ubuntu在线下载鲁班猫SDK源文件”这篇文章
修改根文件系统
修改这个文件SDK/debian/overlay/etc/update-motd.d/00-header

# 选择SDK配置文件
./build.sh lunch
# 如果之前构建过要先删除
rm -f debian/linaro-gnome-rootfs.img
# 构建Debian
./build.sh debian编译完成，是这个文件，记住它，后面需要用到
大小是4个G
下载工具
去鲁班猫网盘下载Linux_Pack_Firmware_v2.29.zip
下载完后解压传到Ubuntu或者先传到Ubuntu再解压，传的位置没要求
同时还要下载一个完整的镜像，把完整的镜像文件传到Linux_Pack_Firmware/rockdev目录下并重命名为update.img
#重命名镜像为update.img，第一个参数根据实际镜像名称而定
mv lubancat-rk3588-debian11-gnome-20260113_update.img update.img#重命名镜像为update.img，第一个参数根据实际镜像名称而定 mv lubancat-rk3588-debian11-gnome-20260113_update.img update.img
解包镜像
# 先在rockdev目录下将所有文件的权限改成可执行，不然会显示权限不够
chmod +x *
# 解包
./unpack.sh
将前面编译出来的根文件系统镜像替换掉output里面的rootfs.img，命名要一致
镜像打包
#进入输出目录
cd Linux_Pack_Firmware/rockdev/output
#打包镜像，根据实际芯片名称而定
#如果有权限问题或者报错
sudo chown -R $USER:$USER ~/Documents/Linux/Tools/Linux_Pack_Firmware/rockdev/output
#rk3588/rk3588s打包执行，下面是两个命令
../afptool -pack ./ update_tmp.img || pause
../rkImageMaker -RK3588 MiniLoaderAll.bin update_tmp.img update.img -os_type:androidos || pause烧录
成功
改成彩色
