JETSON TX1 - TEGRA LINUX DRIVER PACKAGE PROBLEM

I did a few steps:

  • Downloaded from https://developer.nvidia.com/linux-tegra
    Tegra210_Linux_R28.2.0_aarch64.tbz2
    Tegra_Linux_Sample-Root-Filesystem_R28.2.0_aarch64.tbz2

  • sudo tar xpf …/Downloads/Tegra210_Linux_R28.2.0_aarch64.tbz2
    cd Linux_for_Tegra/rootfs/
    sudo tar xpf …/Downloads/Tegra_Linux_Sample-Root-Filesystem_R28.2.0_aarch64.tbz2
    cd Linux_for_Tegra
    sudo ./apply_binaries.sh

    –> /usr/src/linux-headers-4.4.38-tegra
    Installing Image into /boot in target rootfs
    Installing the board *.dtb files into /boot in target rootfs
    Success!

  • sudo ./flash.sh jetson-tx1 mmcblk0p1

    Make sure the target board is connected through
    micro-B USB port and is in recovery mode.

  • also, with Jetson TX1
    sudo reboot --force forced-recovery
    sudo ./flash.sh jetson-tx1 mmcblk0p1
    same result
