[Tinyos-help] using tinyos1.x java on openslug NSLU

[Xavier Orduña]

Hi Muzammil,

I've worked before with NSLU2 and a tinyos network.

My recommendation is that you use the sdk programmed in c language instead
of using the java tools. All you have to do is compile (with the apropriate
gnu arm compiler)  the serial forwarder that you can find in "
tinyos-1.x\tools\src\sf" and copy it to your slug.

I had no problem with OpenWRT last version and tinyos 2.

If you need more help, ask!

Regards,

Xavi
