Cygwin User Notes

This page is used to collect misc. user notes on using TinyOS under Cygwin. The organization is adhoc. Currently, topics are listed as sections.

MIB520 and Cygwin serial ports

In Cygwin the serial ports are accessed as /dev/com1 through /dev/com16 not as /dev/ttyS0 as on Linux. The comX portion of the name corresponds exactly to the Windows port name. Thus, to program a Micaz using the Crossbow MIB520 programming board that enumerated as Windows ports COM13 and COM14 type:

make micaz install mib520,/dev/com13

Note that the /dev directory is not populated by Cygwin. This means that listing the /dev directory under Cygwin will not list the available serial ports. However, using the above syntax will allow access to the ports.

Beware of <cr><lf> vs. <lf> line terminators

Some windows editors will use <cr><lf> instead of <lf> to terminate lines. Unix programs brought over under Cygwin can get confused by this. We have definitely seen this messing up environment settings.

Environment variables under Cygwin

Sometimes when using TinyOS under Cygwin there are problems with the environment variables being recognized. One proposed solution is to place the file /etc/profile.d/tinyos-2.x.sh. ie:

cat /etc/profile.d/tinyos-2.x.sh export MAKERULES=`cygpath -w $TOSROOT/support/make/Makerules` export MAKERULES="$MAKERULES:."

<Can someone verify that this works?>
