1.      备份原始uboot文件。你看到你正在使用哪个平台检查$DEVDIR/64_TX1/Linux_for_Tegra_64_tx1/jetson-tx1.conf中的文件

将文件复制到packages-backup目录

mkdir$DEVDIR/images/packages-backup/bootloader/

cp -rf $DEVDIR/64_TX1/Linux_for_Tegra_64_tx1/bootloader/t210ref/p2371-2180-devkit$DEVDIR/images/packages-backup/bootloader/

cd $DEVDIR/64_TX1/Linux_for_Tegra_64_tx1/bootloader/

cp nvtboot.bin nvtboot_cpu.binu-boot-dtb.bin bpmp.bin warmboot.bin tos.imgtegra210-jetson-tx1-p2597-2180-a01-devkit.dtb$DEVDIR/images/packages-backup/bootloader/

cp $DEVDIR/64_TX1/Linux_for_Tegra_64_tx1/bootloader/t210ref/p2371-2180$DEVDIR/images/packages-backup/bootloader/

 

2.      转到uboot并设置环境变量。您需要导出图像目录路径，以便允许u-boot找到DTC

cd $DEVDIR/64_TX1/Linux_for_Tegra_64_tx1/sources/u-boot_source/

PATH=$DEVDIR/images:$PATH

exportCROSS_COMPILE=/opt/linaro/gcc-linaro-5.3-2016.02-x86_64_aarch64-linux-gnu/bin/aarch64-linux-gnu-

export ARCH=arm64

 

3.      清洁并编译

make distclean

make p2371-2180_defconfig

make

 

PS：错误解决

*** Your dtc is too old,please upgrade to dtc 1.4 or newer

$DEVDIR/images/dtc -v

Version: DTC1.2.0-g37c0b6a0

方法：

cd $DEVDIR/64_TX1/Linux_for_Tegra_64_tx1/sources

git clonegit://git.kernel.org/pub/scm/utils/dtc/dtc.git

cd dtc

make

cp dtc $DEVDIR/images/

 

PS：错误解决

GEN   config-host.h

     LEX convert-dtsv0-lexer.lex.c

make[1]: flex：命令未找到

     BISON dtc-parser.tab.c

make[1]: bison：命令未找到

     LEX dtc-lexer.lex.c

make[1]: flex：命令未找到

CHK version_gen.h

方法：sudo apt-get install flex

     sudo apt-get install bison

 

4.      保存新的二进制文件

mkdir $DEVDIR/images/bootloader

cp $DEVDIR/64_TX1/Linux_for_Tegra_64_tx1/sources/u-boot_source/u-boot{,.bin,.dtb,-dtb.bin}$DEVDIR/images/bootloader

 

5.      现在，将您的u-boot二进制文件复制到Jetpack用于查找它们的目录。正如您在DTB中可以看到的那样，它会在其中寻找

target_board="t210ref";

BOOTLOADER="bootloader/${target_board}/p2371-2180/u-boot-dtb.bin";

 

复制文件运行

cp $DEVDIR/images/bootloader/u-boot{,.bin,.dtb,-dtb.bin}$DEVDIR/64_TX1/Linux_for_Tegra_64_tx1/bootloader/t210ref/p2371-2180/

 

6.      更新烧写uboot

最后将tx1进入recover模式：

关闭设备，移除电源适配器

用自带的Micro USB 转 USB 数据线连接主机与TX1

连接电源适配器

按下POWER按钮

按住FORCE RECOVERY 按钮不放开，同时按一下RESET按钮，等待两秒钟，松开FORCE RECOVERY 按钮

 

$ sudo ./flash.sh -k EBT jetson-tx1mmcblk0p1
