[Tinyos-help] Platform implementation setting TOS_NODE_ID

[Alexandre Buist]

Thanks Urs,

I look around but I can't find anything in the platform files or the
platform.target that would link to tos-set-symbols with TOS_NODE_ID. The
only relevant files I found about tos-set-symbols is the uC msp.rules. Which
should be just fine without modification. 

One thing I noticed, In the mote 2 mote tutorial:
$ make telosb install,1
...
    compiled BlinkToRadioAppC to build/telosb/main.exe
            9040 bytes in ROM
             246 bytes in RAM
msp430-objcopy --output-target=ihex build/telosb/main.exe
build/telosb/main.ihex
    writing TOS image
tos-set-symbols --objcopy msp430-objcopy --objdump msp430-objdump --target
ihex build/telosb/main.ihex 
build/telosb/main.ihex.out-1 TOS_NODE_ID=1 ActiveMessageAddressC$addr=1
...


While in my environement
$ make telosb install,1
...
    compiled BlinkToRadioAppC to build/telosb/main.exe
           10674 bytes in ROM
             283 bytes in RAM
msp430-objcopy --output-target=ihex build/telosb/main.exe
build/telosb/main.ihex
    writing TOS image
cp build/telosb/main.ihex build/telosb/main.ihex.out
    installing telosb binary using the parallel port jtag adapter
...

The thing to notice is that the tos-set-symbols ... does not show up. Could
there be something wong with my environment.

Any thoughts,

Thanks

Hi Alecandre,

The TinyOS environment programs the node id by modifying symbols in the 
compiled binary before flashing it to the mote. I think this is compiler 
and platform dependent (since where the symbols are placed and how to 
access them would depend on the binary format and be platform specific). 
  For the telosb motes, this symbol-changing is done with the command 
tos-set-symbols (it might support other platforms as well). Have a look 
at the documentation of tos-set-symbols.

Cheers,
Urs
