20250409在荣品的PRO-RK3566开发板使用Rockchip原厂的buildroot系统时拿掉经常出现的list-iodomain.sh【直接编译进IMG】
2025/4/9 13:46
缘起，使用荣品的PRO-RK3566开发板，刷Rockchip原厂的buildroot系统时，经常会出现让你检查vccio电源/电压的警告信息。
不想每次刷机之后都去修改shell脚本了，干脆【直接编译进IMG】

【直接修改output有效，至少要修改这里！】

Z:\RK3566_RK3568_Linux5.10_V1.2.0\buildroot\output\rockchip_rk3566_recovery\target\usr\bin\list-iodomain.sh
感觉 Rockchip原厂的buildroot系统 有一个守护进程在定时/定期调用脚本：/bin/list-iodomain.sh。
因此我使用vi一改，那个红色打印马上/立马消失了！
【确认有自启动脚本的死循环，2分钟检查一下vccio的电压！】

【adb shell用top可以看到sleep 120。应该是判断vccio的延迟的脚本？^_】

【泰山派RK3566】Buildroot SDK 使用记录（一）
该脚本的地址就是：/usr/bin/list-iodomain.sh
把最后三行注释掉，如下：
if [ "$1" = "-h" -o "$1" = "--help" ]; then
help_msg
fi
#chk_env
#get_chip_id $1
#echo_msg "Get CHIP ID: $CHIP_ID"
#get_iodomain_val
