General

  • Official Hackers Manual (v1.01) from OpenPandora Ltd, includes warnings about damage and warranties (or loss of).

Board

Pandora PCB rev 5

The Pandora is based upon OMAP3530 and DM3730 System-on-a-chip, that includes a whole family of processors in one single chip:

  • ARM Cortex-A8 CPU
  • PowerVR SGX graphics core
  • C64x+ DSP core

OMAP3530 (600MHz units)

  • OMAP3xxx: Main page on TI site[1]
  • OMAP3530 specific page[2] This lists the features of the chip and has all the applicable Technical Documents

DM3730 (1GHz units)

  • DM3730 specific page[3]

Other OMAP3530 Projects

  • Always Innovating Touch Book[4]
  • Beagle Board Resources[5] As it uses the same SoC, many BB resources are also relevant for the Pandora.
  • Beagle Board Google Group[6]

Cortex-A8

This processor is part of the ARM risc cpu family[7] that is licensed by a lot of hardware vendors. It has multiple command extensions as NEON (similar to MMX for x86 architecture)

  • r1p1[8] Note: OMAP3530 uses rev1p2
  • UPDATE: r2p2 Documentation [9] Note: OMAP3530 uses rev1p2
  • NEON instruction set [10]
  • NEON memory hazards[11]

PowerVR

C64x+

Digital signal processors allow to do complex calculations within only a few cycles

  • CPU and Instruction Set Reference Guide[12]
  • TMS320C6000 Assembly Language Tools v 6.0 Beta User's Guide[13]
  • TMS320C6000 Optimizing Compiler v 6.0 Beta User's Guide[14]
  • TMS320C6000 Programmer's Guide[15]

TPS65950 power IC

  • Main page on TI site[16]

Connectivity

Two usb host ports. Bluetooth,two SD slots with SDIO capability, and a serial UART for adding whatever additional widgets you want (such as a USB GPS system). Solder pads were designed into the PCB for "hacking" in extra internal hardware.

RTC and RS-232?

It has RTC and RS-232 (CMOS level) [17]
