Mainline support was added in linux 2.6.32 and the default config file for Orion boards works. However, this board by default has a wrong arcNumber (526), that prevents a normal kernel from booting. A solution is to edit “mach-types” in the kernel source tree and change 2big network number to 526. Apart from that, there is full support for every hardware component, including LEDs.

This board works well with clunc; main LED will become red while clunc is active.
