    1: [[!meta title="NetBSD/evbarm on NVIDIA Tegra"]]
    2: 
    3: The NetBSD tegra port currently supports the NVIDIA Tegra K1 (32-bit) system-on-a-chip. The [NVIDIA Jetson TK1 development kit](https://developer.nvidia.com/jetson-tk1) is a board based on the Tegra K1 SoC.

   55: # Generating a boot script
   56: 
   57: 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)

   69: # Getting U-Boot
   70: 
   71: 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).
   72: 
   73: # Modesetting
   74: 
   75: ## Console
   76: 
   77: To override the default video mode (auto-detected from display EDID), use the *video* kernel command-line parameter:
   78: 
   79: [[!template  id=programlisting text="""
   80: video=<xres>x<yres>[M][R][-<bpp>][@<refresh>][i][m][eDd]
   81: """]]
   82: 
   83: ## Xorg
   84: 
   85: 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:
   86: 
   87: [[!template  id=programlisting text="""
   88: Section "Device"
   89:     Identifier "DRM Modesetting"
   90:     Driver "modesetting"
   91: EndSection
   92: """]]
   93: 
   94: # GPU (nouveau)
   95: 
   96: To enable the GPU, add the following before the `bootm` command in the boot script:
   97: 
   98: [[!template  id=programlisting text="""
   99: fdt set /gpu@0,57000000 status okay
  100: """]]
  101: 
  102: For the nouveau driver to load successfully, firmware is required:
  103: 
  104: * Install the [sysutils/tegra-firmware](http://pkgsrc.se/sysutils/tegra-firmware) package from pkgsrc.
  105: * 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''.
  106: 
  107: You should see the following messages at boot:
