[Tinyos-help] Increasing Baudrate for Atmega-128

[Varun Jain]

Hi,
I am trying to increase the baudrate of the incoming packet for motes
with atmega-128 processor. I am adding code in  the implementation
Atm128UartP.nc located at /tos/chips/atm128/Atm128UartP.nc as follows:

 

else if (PLATFORM_BAUDRATE == 256000UL)

      m_byte_time = 15;  // 1 TMicor ~= 2.12 us, one byte = 31us ~= 15

 

 

$ java TestSerial -comm serial at COM1:256000

serial at COM1:256000 died - exiting (java.io.IOException: Could not
configure COM1

 TOSComm JNI library runtime error: Error 87.

  The parameter is incorrect.

  in set_params.SetCommState)

                

I am running this in Windows(Cygwin).... Why cant it configure this
baudrate?? How and where is it configured, is it done in
/tools/tinyos/java/ ???

 

Cheers,

 

Varun
