CONFIG_BOOTDELAY 不起作用

[xray-bit]

CONFIG_BOOTDELAY:

Delay before automatcally 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.

我把它设为 0 或者 -2，启动时依旧会有2秒的倒计时：Hit any key to stop autoboot: 1

defconfig 如下：

CONFIG_ARM=y
CONFIG_TARGET_NUC980_IOT=y
CONFIG_FIT=y
CONFIG_BOOTDELAY=-2
CONFIG_SYS_CONSOLE_OVERWRITE_ROUTINE=y
CONFIG_SYS_NO_FLASH=y
CONFIG_SPL=y
CONFIG_HUSH_PARSER=y

Please also update the env.txt of u-boot. Find "bootdelay=" from env.txt.
