NVIDIA Tegra SoCs are well supported by mainline U-Boot.

U-Boot releases may be obtained from:

Features that already work are:

  • It boots!
  • Serial console.
  • SD/eMMC.
  • USB Host:
    • USB networking for network booting.
    • USB keyboard enabled on some boards.
  • Display controller, for some SoCs and boards - mainly Tegra20/30.
  • bootz, sysboot, pxe commands, shell, and scripting available for easy distro booting support.
  • Extremely basic PMIC support necessary to boot the main CPUs.
  • I2C master.
  • SPI master (e.g. for boot flash programming).
  • NAND (Tegra20 only, for boot flash programming).
  • I2C slave (Toshiba AC100 specific NVEC keyboard support).

A probably-incomplete list of features that are not yet implemented is:

  • Advanced (high-speed) transfer modes for SD and eMMC. IO voltage scaling.
  • PCIe (e.g. for PCIe-based network devices on some boards).
  • USB device mode and OTG. (device mode support is work-in-progress, and nearly complete).
  • SKU awareness (SKU-specific clock and thermal limits).
  • POR (Plan Of Record) clocks.
  • HDMI display
  • LCD panel support on many boards (especially Tegra114 and later).
