Please note:

1. Uart/debug out from /dev/ttyUSB3
   
   
2. Plugin HDMI interface directly ( DON'T VGA transfer HDMI )
   error message: ...

   tegra_nvdisp_head_enable, failed head enable
   ( seems to hang )
   
   
3. hung on "Please complete system configuration setup on the serial port provided by Jetson's USB device mode connection. e.g. /dev/ttyACMx ..."
   => Setting configuration with GUI on the monitor

Build Kernel:

• Download kernel source code from git:

cd Linux_for_Tegra/
./source_sync.sh
When prompted enter a ‘tag’ name, as provided in the release notes.

tag name:
(Open another terminal after running source_sync.sh)
$ cd Linux_for_Tegra/sources/kernel/kernel-4.9
$ git tag -l tegra-l4t*
...
...
tegra-l4t-r32.4.2
tegra-l4t-r32.4.3
tegra-l4t-r32.4.4
tegra-l4t-r32.5
tegra-l4t-r32.5.1
tegra-l4t-r32.6.1
tegra-l4t-r32.7.1

$ cd sources/

• Build the kernel image with the following build.sh:

#!/bin/bash

pwd=$(dirname $(readlink -f $0))
TEGRA_KERNEL_OUT=out
export CROSS_COMPILE=/opt/gcc/linaro-7.5-aach64/bin/aarch64-linux-gnu-
export LOCALVERSION=-tegra

if [ -z "$TEGRA_KERNEL_OUT" ]; then
    mkdir -p $TEGRA_KERNEL_OUT
fi

make ARCH=arm64 O=$TEGRA_KERNEL_OUT tegra_defconfig

make ARCH=arm64 O=$TEGRA_KERNEL_OUT -j8

• Replace original Image

$ cp out/arch/arm64/boot/Image Linux_for_Tegra/kernel/
$ sudo ./apply_binaries.sh

ref:
1. TX2i tegra_nvdisp_head_enable fails if HDMI is connected after boot
2. Jetson Nano平台更改DP1上DisplayPort的设备树3
3. 備份與還原 NVIDIA® Jetson AGX Xavier
