Hi Veitch,

Boot to U-Boot prompt and then execute the below command:

setenv bootdelay 0

doHi Keerthy,

thanks for your reply, I know it can be changed by uboot command, but what we exactly want is setting it in the uboot code, instead of manually setting it for each board, and I have tried to revise CONFIG_BOOTDELAY, but it doesn't work.
