Hi Jon. So, if I understood correctly, the internal RAM you're talking about is the one coming with the OMAP itself. Additionally, you could count on the RAM coming with the board and the internal caches available, right? Or are you using the term "internal RAM" to refer to the L1 / L2 caches (if any)? Regarding peripheral support, then this means that the driver support should be basically the same among revisions, right? Thanks for your reply. It has been really helpful.

Now from the user point of view not too many changes were made (ie. no new peripherals that I recall) but there were some new registers added in some modules. The OMAP1611 became the OMAP1621 after it was revised. So if you have a OMAP1611 this was the original device. > > The OMAP1623 is simply a OMAP1621 with stacked DDR memory. > > Hope this helps. > > Jon -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
