I'm not sure what's going on here with the micaz schematics or how it's
implemented in software. I know on the mica2 schematics, the flash is
controlled by USART1
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)?
because normally the external flash is controlled by UART1 interface of the
ATmega128 processor (in this case there are not
software
issue going on here.

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

Dear all,
i tried to use TinyAlloc interface but the results are
really
it, and the flash has to request access before using it, etc.

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 only

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
