Thanks Miklos,
Now we've found that initRadio function run only once.
We've also done a simple experiment as follows.
We deleted the annotation "@exactlyonce()" before interface PlatformInit
& SoftwareInit, in file /tos/chips/rf230/RF230LayerP, Line37&38. Then put
the SoftwareInit.init() into a cycle, in file /tos/system/origin/RealMainP,
Line75. We do this just want to see if we delete the keyword "exactlyonce",
can the function initRadio() run many times. But the result seem didn't.
So if we must restart RF230 in a application program, what should we do?
