Thanks anyway, I found the problem with your previous hint!
For other having a similar problem: it appears that the Mica2 motes came
in different versions using different frequencies (somewhere between
300MHz and 800MHz). The motes I was using support 315MHz (it says so on
a sticker). It appears that TinyOS 2.x by default configures the motes
for 434MHz, which is not supported by my hardware.
The solution is to add the following line (or similar if your motes
support a different frequency, for a list of frequencies look into
$TOSROOT/tos/chips/cc1000/CC1000Const.h):
CFLAGS += "-DCC1K_DEF_PRESET=(CC1K_315_178_MHZ)"
Cheers,
Urs
