[Tinyos-devel] cc2420 radio stack and deputy

[Vlado Handziski]

I am getting strange behavior from the apps when testing radio stack apps
with deputy. My deputy version includes the original patches, but not this
last one. I am not sure if this is the cause, but RadioCountToLeds for
example (on shimmer and on telosb). Can anyone confirm this?
