[Tinyos-help] mica2 "Failed to enter programming mode"

[Neal Patwari]

I've in the past used a MIB510 to program my mica2 motes and had no 
problem.  Now, I have only a MIB520 programming board, and I can't 
understand how to properly program it.  I first run the command:
  export MOTECOM=serial at COM13:mica2

Then, in the Blink directory, I use:
  make mica2 reinstall.23 mib510,/dev/ttyS12

The output of this command is usually:
  set-mote-id build/mica2/main.srec build/mica2/main.srec.out-26 26
  Could not find symbol TOS_LOCAL_ADDRESS in build/mica2/main.exe, 
ignoring    symbol.

   Failed to enter programming mode.
   make: *** [program_bl] Error 2

The red ISP light remains lit after this. Even though I get this error, 
when I restart the mica2, the device has in fact been programmed with 
the new program.

And, once in a while, the "failed to enter..." error does not happen - 
it finishes successfully.

(My computer 'Ports' are COM13 and COM14 for my USB cable connection to 
the MIB 520.  I've used 'mib510' instead of 'mib520' on the command 
line because I'm told my version of Tinyos (1.1.15) does not have the 
'mib520' defined.)

Can anyone tell me how to properly program a mica2 using the MIB 520?

Thank you,
Neal
