Hi, I just read the "The ARM Architecture Version 6 (ARMv6)" whitepaper. It seems all new v6 features can be toggled on/off so my guess is that from an ISA point of view a working emulator solution should work on the physical device. However there are several performance improvements (such as ASID) to be used on armv6. Quoting the paper: "ARMv6 maintains 100% backward compatibility at the binary level for operating systems and applications." /Andreas
