[Tinyos-help] Bugs found in Deluge/TOSBoot

[Simon Willis]

Hi Mingze,

I found the same problem when I was trying to get Deluge to work on my 
Mica2-based nodes. I think that the pre-compiled binary for mica2 may 
not have been recompiled with the new version of TOSBootM.nc. I needed 
to have TOSBoot working ASAP and they way I got it working was to 
download an earlier version of TOSBootM.nc off CVS and then it worked.

Deluge seems to work fine with general problems, but I have a problem 
when I use Deluge to update my Surge-like program. All the nodes seem to 
reprogram themselves, but none of them talk. It's very odd. I've had to 
move on and get on with something else.

Cheers,

Simon
