Isn't SPI implemented with USART1?
Or was I out behind the barn when they passed out?

Hi David,
i would like to ask you a question: do you know if the way FlashBridge
gets access to the flash, is controlled by SPI interface or UART1 interface
(ATmega128)?

Are you accessing the Flash memory while using the radio? I

into some serious issues doing this with the MicaZ. The problem, I

is in the bus arbitration - because both the flash and the radio

bus before
using it, and the flash has to request access before using it, etc.

Ah, yes - 1.3V is a definit problem. You need to be able to source
2.7
volts minimum, with 75+ mA. I recommend going above 2.7 volts to
about
3.3-3.6 volts just to allow for some voltage

How much RAM is your program consuming at compile time? The MicaZ is
notorious for running out of RAM just when you need it because it on

You need to return the same pointer that you get in receive(TOS_MsgPtr m),
the system will recycle it. There isn't any way for you to free it
yourself. Perhaps you can run your program under TOSSIM or something
so your can trace memory usage to see if you've really got a leak.
Otherwise you could
