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 a OMAP3530 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

  • OMAP35x: Main page on TI site[1]
  • OMAP3530 specific page[2] This lists the features of the chip and has all the applicable Technical Documents

Other OMAP3530 Projects

  • Always Innovating Touch Book[3]
  • Beagle Board Resources[4] As it uses the same SoC, many BB resources are also relevant for the Pandora.
  • Beagle Board Google Group[5]

Cortex-A8

This processor is part of the ARM risc cpu family[6] that is licensed by a lot of hardware vendors. It has multiple command extensions as NEON (similar to MMX for x86 architecture)

  • r1p1[7] Note: OMAP3530 uses rev1p2
  • UPDATE: r2p2 Documentation [8] Note: OMAP3530 uses rev1p2
  • NEON instruction set [9]
  • NEON memory hazards[10]

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

  • OMAP35x: Main page on TI site[16]

Display

  • Screen datasheet (TD043MTEA1)[17] The Pandora uses the display from the Archos 605 Media Player. However, on the Archos LCD the pinout is reversed as well as the cable having a 45 degree angle which would make it fail to line up with the Pandora LCD cable in the lid. --[18]

Input

Keyboard

  • The keyboard is listed on p.20 of the hackers manual, and a more readable version is shown here.

Touchscreen

  • TSC2046: ADS7846 compatible touch screen controller[19]
