Cortex-A8 technical docs

Key documentation

• OMAP3530 TRM
• TPS65950 TRM
  (documentation for the OMAP3 companion chip that’s used in practically every OMAP3 board. The TWL4030 is another companion chip that’s used, but from a programmer’s perspective it’s functionally equivalent to the TPS, so the TPS manual is a suitable reference for both)
• OMAP3530/25/15/03 Applications Processor Silicon Errata
• TPS65950 silicon errata
• Cortex-A8 TRM
• ARMv7-AR ARM – Follow the link through to silver.arm.com and you should be able to create an account to allow you to download the ARMv7-AR ARM
• AM37/DM37x TRM (new SoC used in BeagleBoard-xM), errata

Machine-specific documentation

• Beagleboard reference manuals and design materials (including -xM docs)
  • (Above page probably needs updating in light of this post – so in the mean time, be sure to follow the “…latest” files listed in the post.)
• Beagleboard x-loader, u-boot and sample linux kernel source
• Pandora wiki and hacker’s manual
• Touch Book wiki
• Tegra 2 TRM (registration via company email address required)
• Toshiba AC100 schematic (password protected PDF, convert to Postscript and back again to remove)
• Raspberry Pi hardware
