Hi teri,

Are you using the devkit or custom board for Xavier NX?
What’s your Jetpack version in use?

Do you mean that you want to disable the frame buffer showing the log on external monitor?

–yes，I want to disable the frame buffer showing the log on external monitor when booting
Jetpack version 4.5.0

There are 2 methods to remove frame buffer:
1. Disable kernel config CONFIG_FRAMEBUFFER_CONSOLE

1-1: check the result of the following command

zcat /proc/config.gz |grep FRAMEBUFFER_CONSOLE

1-2: If the above config exists, then disable it in defconfig

2. Remove console=tty0 in kernel command line

2-1: check current kernel command line

$cat /proc/cmdline

2-2: If console=tty0 in kernel command line, then remove it in p3668.conf.common

as the first method is too complicated，I choose the second method ,and it works after I modify the file - p3668.conf.common and flash again.
