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)

• 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

• specifications

• Texas Instruments Wiki

DM3730 (1GHz units)

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]

C64x+

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

• 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]
