The method of delay Modification during uboot start-up in SAIL-IMX6
The platform we need to use is sail-imx6.
The system is linux4.1.15
When the Linux system starts, there is a 1s delay in the uboot phase. How to modify it if you want to increase the delay or reduce the delay?
Modify the uboot code of linux:
/ sail-imx6q-uboot-2015.04/include/configs/mx6sabre_common.h (104lines)
-# define CONFIG_BOOTDELAY 1
+ # define CONFIG_BOOTDELAY 1
In this way, there is no 1s delay, and you can change it to other values.
Through the above steps, can you modify it by yourself? you can carry out a simple experiment.
