Cortex-A9 port

This section of the wiki contains information about the port of RISC OS to the ARM Cortex-A9 architecture. The initial target is the OMAP 4 family of system on chip devices from Texas Instruments, which are in turn used in their ‘Pandaboard’ reference designs.

Getting started with the OMAP 4:

• Status of the OMAP 4 port – what does work, what doesn’t
• Starting from nothing – how to prepare an SD card containing a ROM image, and how to prepare the HardDisc4 disc image
• Forum discussion thread – main discussion for all things relating to the Cortex-A9/OMAP4 port
• For advice regarding the bootscript, please check the forum or here for more info.

Technical information for the OMAP 4 specifically:

• OMAP4430 TRM (ver.AA)
• OMAP4460 TRM (ver.M)
• OMAP4470 TRM (ver.E)

General Cortex-A9 information:

• ARMv7 software compatibility list
• A guide for programmers on how they can update their code to run on Cortex-A9 CPUs
