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.
