Tegra/Mainline SW/U-Boot

< Tegra‎ | Mainline SW

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

U-Boot releases may be obtained from:

• ftp://ftp.denx.de/pub/u-boot/ releases, via download.
• http://git.denx.de/?p=u-boot.git;a=summary releases and overall development code, via git.
• http://git.denx.de/?p=u-boot/u-boot-tegra.git;a=summary Tegra-specific latest development code, via git.

Features that already work are:

• It boots!
• Serial console.
• SD/eMMC.
• USB2 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).
• USB2 device mode and OTG. (device mode support is work-in-progress, and nearly complete).
• USB3 controller.
• SATA.
• 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).
