h2. Overview At present the port consists of three components: * A [[Hardware Abstraction Layer|HAL]] targetting TI's "OMAP4430":http://www.ti.com/product/omap4430 / "OMAP4460":http://www.ti.com/product/omap4460 system-on-chip devices * The standard 'HAL' version of the RISC OS 5 kernel and the standard ROM modules * Additional custom driver modules, e.g. [[MUSBDriver]], [[OMAPVideo]] as required At present the port is known to be functional on the following hardware devices: * "Pandaboard ES":http://pandaboard.org/node/300/#PandaES * "Pandaboard":http://pandaboard.org/node/300/#Panda The OMAP 4 port has a "stable version":/content/documents/stable-releases available to "download":/content/downloads/pandaboard. Users with an adequate backup strategy in place may wish to try the new features present in the "beta version":/wiki/documentation/show/Software%20information:%20Beta%20OMAP4%20ROM instead. h2. Current status The [[RISC OS Roadmap]] covers items which are not specific to the OMAP 4, and the "bug tracker":/tracker covers defects in existing components. This table covers planned future tasks or areas that are yet to be implemented on OMAP 4. table(bordered). |_\3. Enhancements to existing OMAP 4 functionality | |_. Task |_. Description/Status |_.
