嵌入式VS-RK3288板卡 Linux 修改BOOTDELAY介绍

uboot进入kernel中间的延时时间可以通过BOOTDELAY这个宏来控制。修改uboot/common/Kconfig文件

config BOOTDELAY

int "delay in seconds before automatically booting"

default 0

depends on AUTOBOOT

help

Delay before automatically running bootcmd;

set to 0 to autoboot with no delay, but you can stop it by key input.

set to -1 to disable autoboot.

set to -2 to autoboot with no delay and not check for abort

See doc/README.autoboot for details.

default 0 表示不延时，1表示延时1s。
