FAQ_MA35D1 Disable Console to Accelerate Booting by Buildroot

[ytliu6]

The booting time of an image created using Buildroot is faster compared to Yocto, primarily because Buildroot employs the busybox system, whereas Yocto utilizes the systemd system.

If your goal is to further decrease the booting time, an effective approach is to deactivate the console log, which significantly accelerates the boot process. It's important to note that the log level influences whether error messages are displayed or not. Thus, exercise caution when configuring this setting.
