huh....not sure what or why your PFLAGS is including mica2 stuff
when you seem to be building for micaz. That is probably the source
of your make error. I did not make any changes to the standard
contrib/xbow makefiles for either platform, so if you did,
maybe you shouldn't. I don't think you need an explicit ref
to the platform dir, as necc has many and nefarious ways of
including code in the TOS tree.
What you were supposed to find while searching was one of many
references to my posted code that uses ACKs on mica2,z which I
was too lazy to look up yet again (2L2LUYA):
http://www.etantdonnes.com/Motes/robocode.tar.gz
This is all assuming TOS1.x not T2, of course.
Beyond that, I'm not much help.

Thank you very much, Mike.
I did a Google on your name and ACK and found some related topics. So
I tweaked the code but I got some a compiler error:
MyComponent.nc:9: component CC2420RadioIntM not found
C:/tinyos/cygwin/opt/tinyos-1.x/tos/platform/mica2/HPLPowerManagementM.nc:42:
expected component `CC2420RadioIntM', but got component
'HPLPowerManagementM'
I guess the error is more related to my make file.
The makefile I got from Crossbow for my micaZ is:
COMPONENT=MyComponent
XBOWROOT=%T/../contrib/xbow/tos
PFLAGS= -I$(XBOWROOT)/platform/mica2
include ../MakeXbowlocal
include $(TOSROOT)/tools/make/Makerules
It worked some Blink, etc. But if I change .../platform/mica2 to
/platform/micaz, I got a lot of errors.
Could you give me some hints on this issue.
Thanks again.

Assuming you are using TOS 1.x, the TOS_Msg.ack field will be != 0
in sendDone() if an ACK is received from the destination mote. When ACKS
are enabled the transmitter waits until an ACK reception times out
before
calling sendDone(). Search back on this list with my name and "ACK"
to see
massive amounts of (questionable) advice...
A good search starting point is:
