Phil, where may I find a doc, if any, that summarizes all the differences between TinyOS 1.x and 2.x configurations, related to the cc2420 protocol? I'm trying to update a cc2420-based platform, which is already compatible with 1.x, to receive 2.x packets, but it is not that easy, just looking at the TinyOS code...

The packet formats are different. 802.15.4 has different packet formats depending on the bits in the frame control field (FCF). For example, there are different source and destination addressing modes, encryption, etc. TinyOS 1.x does not have a source address in the packet; TinyOS 2.x does. So the packet formats are not compatible.
