Compile the results u-boot, U-boot.bin, U-boot-dtb.bin, U-BOOT.DTB 4 copies of the files to ~/linux_for_tegra/bootloader/t210ref/p2371-2180/

It is recommended that the original U-boot file be placed in the folder Uboot_backup as an error recovery file.

Run the Devkit in recover mode, and then run the following command in the host host ~/linux_for_tegra/directory to burn the u-boot:

$ sudo./flash.sh-k EBT jetson-tx1 Mmcblk0p1

Finish. 4. problems encountered in compiling:

1), Prompt Error:bad value (armv8-a) for-march=switch

The reason is that there is no arm64 and should be set to Arch=arm

2), tips missing compiler-gcc6.h

This latest file is required because of the gcc6.3 version of the compiler. Download it online and put it in the ~/u-boot/include/linux/.

3), hint that the DTC version is too old

Workaround, install the latest Device-tree-compiler:

$ sudo apt-get install Device-tree-compiler

It can be compiled successfully after installation.
