TX2入门教程基础篇-备份和恢复

说明：

• 介绍如何为TX2进行备份和恢复

（0）准备：

• 准备好利用Jetpack刷过机的Ubuntu的主机(HOST PC)
• 在利用Jetpack刷机时候，建立目录TX2，并保存有JetPack-L4T-*-linux-x64.run文件
• 再进行第一次刷机之后会增加其他目录，并生成子目录64_TX2

(1) 备份:

• 进入HOST PC的JetPack安装目录下bootloader目录

$ cd ~/TX2/64_TX2/Linux_for_Tegra_64_tx2/bootloader

• 连上TX2，并进入recovery模式(通电，按住recovery键3秒，再按一下reset键)
• 检查是否出现0955:7140 Nvidia Corp

$ lsusb

• 从TX2下载镜像：
  
  

  $ sudo ./flashNew.sh -r -k APP -G my_backup.img jetson-tx2 mmcblk0p1

     原来的flash.sh缺少 -G 参数支持，改为新增加脚本flashNew.sh
  

• flashNew.sh脚本如下：

#
# flash.sh: Flash the target board.
#       flash.sh performs the best in LDK release environment.
#
# Usage: Place the board in recovery mode and run:
#
#   flash.sh [options]  
#
#   for more detail enter 'flash.sh -h'
#
# Examples:
# ./flash.sh  mmcblk0p1           - boot  from eMMC
# ./flash.sh  mmcblk1p1           - boot  from SDCARD
# ./flash.sh  sda1            - boot  from USB device
# ./flash.sh -N :/nfsroot  eth0   - boot  from NFS
# ./flash.sh -k LNX  mmcblk1p1        - update  kernel
# ./flash.sh -k EBT  mmcblk1p1        - update  bootloader
#
# Optional Environment Variables:
# BCTFILE ---------------- Boot control table configuration file to be used.
# BOARDID ---------------- Pass boardid to override EEPROM value
# BOOTLOADER ------------- Bootloader binary to be flashed
# BOOTPARTLIMIT ---------- GPT data limit. (== Max BCT size + PPT size)
# BOOTPARTSIZE ----------- Total eMMC HW boot partition size.
# CFGFILE ---------------- Partition table configuration file to be used.
# CMDLINE ---------------- Target cmdline. See help for more information.
# DEVSECTSIZE ------------ Device Sector size. (default = 512Byte).
# DTBFILE ---------------- Device Tree file to be used.
# EMMCSIZE --------------- Size of target device eMMC (boot0+boot1+user).
# FLASHAPP --------------- Flash application running in host machine.
# FLASHER ---------------- Flash server running in target machine.
# IGNOREFASTBOOTCMDLINE -- Block fastboot from filling unspecified kernel
#                          cmdline parameters with its defaults.
# INITRD ----------------- Initrd image file to be flashed.
# KERNEL_IMAGE ----------- Linux kernel zImage file to be flashed.
# MTS -------------------- MTS file name such as mts_si.
# MTSPREBOOT ------------- MTS preboot file name such as mts_preboot_si.
# NFSARGS ---------------- Static Network assignments.
#              :::
# NFSROOT ---------------- NFSROOT i.e. :/exported/rootfs_dir.
# ODMDATA ---------------- Odmdata to be used.
# ROOTFSSIZE ------------- Linux RootFS size (internal emmc/nand only).
# ROOTFS_DIR ------------- Linux RootFS directory name.
# SCEFILE ---------------- SCE firmware file such as camera-rtcpu-sce.bin.
# SPEFILE ---------------- SPE firmware file path such as bootloader/spe.bin.
# FAB -------------------- Target board's FAB ID.
# TEGRABOOT -------------- lowerlayer bootloader such as nvtboot.bin.
# WB0BOOT ---------------- Warmboot code such as nvtbootwb0.bin

• 大概要花30分钟左右完成镜像下载。
• 备份在~/TX2/64_TX2/Linux_for_Tegra_64_tx2/目录下
• 分配权限，并压缩保存：

$ sudo chmod 744 my_backup.img
$ tar -zcvf my_backup.img.zip my_backup.img

• 备份后也可以挂载到ubuntu下进行相应编辑

mkdir testimg
sudo mount -o loop my_backup.img  testimg

(2) 恢复:

• 进入HOST PC的JetPack安装目录下bootloader目录

$ cd ~/TX2/64_TX2/Linux_for_Tegra_64_tx2/bootloader

• 复制my_backup.img为system.img

$ sudo cp my_backup.img system.img

• 连上TX2，并进入recovery模式(通电，按住recovery键3秒，再按一下reset键)
• 检查是否出现0955:7140 Nvidia Corp
• 
  

$ lsusb

• 退出到上一层目录，使用flash.sh开始烧录

$ cd ../
# As an example, you should be in ~/TX2/64_TX2/Linux_for_Tegra_64_tx2/
$ sudo ./flash.sh -r  jetson-tx2 mmcblk0p1

• 如果想恢复到SD卡或U盘，[参考编译文章][1]
• 大概要花费15分钟时间完成恢复镜像。
