   The Tegra kernels need a .dtb for your board to boot. The dtb here was updated on 2017-04-13 and is generated from a Linux 4.10.10 source tree. [NVIDIA Jetson TK1 .dtb](http://ftp.netbsd.org/pub/NetBSD/misc/jmcneill/tegra/tegra124-jetson-tk1.dtb)

   # Getting U-Boot
   
   Jetson TK1 boards come with Linux4Tegra R19.x installed, which doesn't use U-Boot. The easiest way to get U-Boot is to upgrade to Linux4Tegra R21.x (Linux PC or VM required) following the [quick start guide](http://developer.download.nvidia.com/embedded/L4T/r21_Release_v4.0/l4t_quick_start_guide.txt).
   
   U-Boot for Jetson TX1 is available in pkgsrc: [[!template id=pkg category="sysutils" name="u-boot-jetson-tx1"]].
   
   # Modesetting
   
   ## Console
   
   To override the default video mode (auto-detected from display EDID), use the *video* kernel command-line parameter:
   
   [[!template  id=programlisting text="""
   video=<xres>x<yres>[M][R][-<bpp>][@<refresh>][i][m][eDd]
   """]]
   
   ## Xorg
   
   To be able to use the mode setting features of the Tegra DRM driver, you must use the xf86-video-modesetting driver. Put this in xorg.conf:
   
   [[!template  id=programlisting text="""
   Section "Device"
       Identifier "DRM Modesetting"
       Driver "modesetting"
   EndSection
   """]]
   
   # GPU (nouveau)
   
   To enable the GPU, add the following before the `bootm` command in the boot script:
   
   [[!template  id=programlisting text="""
   fdt set /gpu@0,57000000 status okay
   """]]
   
   For the nouveau driver to load successfully, firmware is required:
   
   * Install the [[!template id=pkg category="sysutils" name="tegra-firmware"]] package from pkgsrc.
   * Extract the contents of [tegra-nouveau-firmware.tar.gz](http://cdn.netbsd.org/pub/NetBSD/misc/jmcneill/tegra/tegra-nouveau-firmware.tar.gz) to ''/libdata/firmware/nouveau''.
   
   You should see the following messages at boot:
   
   [[!template  id=programlisting text="""
