With TosThreads there are at least two different levels of Boot.booted, TinyOSMainP.TinyOSBoot.booted and TinyOSMainP.Boot.booted.
The first, TinyOSMainP.TinOSBoot.booted, is what gets signalled after the Thread start runs (it needs to run first before any of the normal TinyOS initilization starts up because it wraps the TinyOS stuff inside a thread). What gets run as part of TinyOSMainP.TinyOSBoot.booted is all the normal TinyOS initilization code, platform.init etc. When the init code is done, then TinyOSMainP.Boot.booted is signaled when tells the rest of the system to go ahead. For TOSThreads to work it wraps the main TOS task level (sync level) in a thread, the TOSThread. You can figure all this out for yourself, by looking at the generated app.c and searching for TinyOSMainP__TinyOSBoot__booted and following the calls backwards. That provides some level of insight and perhaps makes deciphering the wiring easier. TOSThreads was added sometime after the initilization code existed for TinyOS 2. So what was done was to simply wrap the TinyOS initilization code in some TOSThreads start up code. Once this code executes, then it make good sense for the TinyOS startup code to run. It is similar to an operating system with many more resources such as virtual memory. It first establishes the environment for the executing code and then that code executes its initilization code. And it really does just work. So I'll byte why do you "need" an answer for this? eric On Mon, Mar 22, 2010 at 3:11 PM, sadun silva <silva.sa...@gmail.com> wrote: > Hi all, > > > Sorry for multiple copies.
