Installation

Currently only booting via fusee gelee is successful. It requires custom u-boot and a built fork of grate kernel. Check links below.

Hardware status (mainline)

Status Hardware Info
Y Booting Booting is available via loading custom U-Boot and kernel via fusee gelee.
P U-Boot U-Boot is fully functional and can be loaded, but can not be written into SPI flash.
N Panel Hydis HV101HD1 LCD SuperIPS+ HD panel through DSI-A port.
Y HDMI output HDMI works, but output is 1080p due to Tegra 3 limitations.
Y Touchscreen Used Atmel MXT1664 touchscreen.
Y USB One full size USB 2.0 in dock or via 36 pin adapter.
Y SD cards MicroSD card and full sized SD card (recognized as USB drive) in dock.
Y Internal memory eMMC by SanDisk. SPI flash W25Q32 4MB.
P GPS Broadcom GPS BCM4751 is used. Device tree has proper bindings but device itself has weak signal.
P WiFi Uses Azurewave AW-NH665 BCM4330. NVRAM is missing.
Y Bluetooth Uses Azurewave AW-NH665 BCM4330B1.
Y GPIO keys There are 3 keys on GPIO: Power, Volume up, Volume down.

Additionally GPIO-keys like are LID sensor and Audio dock line-out detect.

Y Vibro VivoTab RT has GPIO based vibrator.
N Dock Keyboard Both pad and dock have Nuvoton NPCE795LA0BX embedded controller which handles battery data, charding, leds, keyboard and touchpad.
Y Battery/Charger Driver is based on Texas Instruments bq24725 SMBus Charge Controller driver and GPIO charger but works through pad/dock EC. Charging and charge level of both batteries are shown correctly.
Y PMIC Transformers use Texas Instruments TPS659110 PMIC and TPS62361 core regulator.
P Sound Sound codec is RT5640. Kernel driver and tegra_rt5640 driver are in grate master.
Y Thermal sensor NCT1008 ON Semiconductor LM90 series thermometer.
Y Orientation sensors Include Invensense mpu6050 IMU and Asahi-Kasei AK8975 3-axis digital compass.
N Light sensor Driver Capella CM3218.
Y Torch MFD Tablet has separate MFD for rear camera flash - TI TPS61050/61052 Boost Converter, and it works.
N NFC
N Front camera
N Rear camera
P ULP GeForce GPU Acceleration partially works.
