The PandaBoard is a low-power, low-cost single-board computer development platform based on the Texas Instruments OMAP4430 system on a chip (SoC). The board has been available to the public at the subsidized[1] price of US$174 since 27 October 2010. It is a community supported development platform.[2]

The PandaBoard ES is a newer version based on the OMAP4460 SoC, with the CPU and GPU running at higher clock rates. The board has been available to the public at the subsidized price of US$182 since 16 November 2011. Like its predecessor, it is a community supported development platform.[3]

Features

The OMAP4430 SoC on the PandaBoard features a dual-core 1 GHz ARM Cortex-A9 MPCore CPU, a 304 MHz PowerVR SGX540 GPU, IVA3 multimedia hardware accelerator with a programmable DSP, and 1 GiB of DDR2 SDRAM. The PandaBoard ES uses a newer SoC, with a dual-core 1.2 GHz CPU and 384 MHz GPU. Primary persistent storage is via an SD Card slot allowing SDHC cards up to 32 GB to be used. The board includes wired 10/100 Ethernet as well as wireless Ethernet and Bluetooth connectivity. Its size is slightly larger than the ETX/XTX Computer form factor at 4 in × 4.5 in (100 mm × 110 mm). The board can output video signals via DVI and HDMI interfaces. It also has 3.5 mm audio connectors. It has two USB host ports and one USB On-The-Go port, supporting USB 2.0.[4]

Operating systems

The device runs the Linux kernel, with either traditional distributions or the Android or Mozilla Firefox OS[5] user environment. Optimised versions of Android and Ubuntu are available from the Linaro Foundation. Linaro has selected the PandaBoard to be one of the hardware platforms they support with monthly build images.

OpenBSD supports PandaBoard.[6] FreeBSD added PandaBoard support in August 2012.[7]

A version of RISC OS 5 is actively developed .[8]

QNX Neutrino 6.5.0 SP1 and 6.6.0 have Board Support Packages for the PandaBoard and PandaBoard ES.[9]

Graphics

The PandaBoard has an integrated SGX540 graphics processor and provides 1080p HDMI output.[10] This GPU supports OpenGL ES 2.0, OpenGL ES 1.1, OpenVG 1.1 and EGL 1.3.

The situation for Linux - x11 utilizing hardware floating point libraries is PowerVR's SGX540 GPU hardware is unusable without a GPU driver. Furthermore, PowerVR will not release documentation so that an open source driver could be produced. This all adds up to the GPU hardware being unavailable, so the above-mentioned features of course will not function. To be perfectly clear, a Pandaboard es will not play any low quality video, so 1080p output via the HDMI is certainly and proven not possible.

Due to PowerVR making the driver unavailable, and withholding the documentation on the GPU hardware, the only alternative is the difficult and inefficient reverse engineering method to develop a GPU driver. An effort was started in July 2012,[11] but as of June 2013 there is no visible progress.

The Linaro Linux project had a Linux x11 software floating point GPU driver available, but all current efforts with ARM Linux seem to be utilizing the hardware floating point libraries. The soft/hard floating point systems are not compatible.

Clock

The PandaBoard has a real-time clock, but it does not have a battery to save the time when power is removed. As an alternative, a software clock can set the clock time at bootup based on the time of the last modification to the file system so that times stored in files will be more reasonable.[12] NTP can set the correct date and time if the PandaBoard has network access to an NTP server.
