[Tinyos-help] SF problem

[Michael Schippling]

I'm assuming that there is a space before -comm (" -comm ") because
it's not visible in your message...

If it's crashing in MoteIF its probably trying to open the serial port.
There might be some difference in the environment that you get from exec().
Or there may be different permissions needed. You could try execing
a bash script to see what you are really getting, or instrumenting the
SF code to print trace messages at relevant points.

not much help, I know...
