Flashing the Boot Loader and Kernel

This section describes the steps required to flash and boot the target Tegra device. It also

provides usage information for the

flash.sh helper script.

Flash Procedure

First, flash the board with the boot loader and kernel, and, optionally, flash the rootfs to

internal eMMC.

Prerequisites

The following directories must be present:

• /bootloader—boot loader plus flashing tools (NvFlash, CFG, BCTs, etc.)

• /kernel—a kernel zImage /vmlinux.uimg, DTB files, and kernel modules

• /rootfs—the root file system that you download (This directory starts empty and you

populate it with the sample file system.)

• /nv_tegra—NVIDIA

Tegra

user space binaries and sample applications

You must also have the USB cable connected to the recovery port prior to running the

commands listed in the procedure. For more information, see the Requirements

topic in

this section.

To flash the boot loader and kernel

1. Put the target board into reset/recovery mode. Do so by first powering on the board

and then holding the recovery button, and then pressing the reset button as

described in the Quick Start Guide for the board.

2. Run the

flash.sh script that is in the top level directory of this release. The script

must be supplied with the target board (

jetson-TX1) for the root file system:

$ sudo ./flash.sh <platform> <rootdev>

• If the root file system will be on a USB disk, execute the script as follows:

$ sudo ./flash.sh <platform> sda1

Note: If a SATA device is connected, that device enumerates as sda1.

• If the root file system will be on an SD card, execute the script as follows:

$ sudo ./flash.sh <platform> mmcblk1p1

• If the root file system will be on the internal eMMC, execute the script as follows:

$ sudo ./flash.sh <platform> mmcblk0p1

Where <platform> is jetson-TX1.

The above examples are for u-boot. For fastboot, add the following argument:
