Yes, Matchbox is what I'm using. Sorry for forgetting to mention (as well
as my platform MicaZ).
Anyway, I made the changes you suggested and it works like a charm. Thanks
a lot!

If you're talking about Matchbox, it uses a ready() event that signals when
the file system is ready. Just make your component provide the
implementation for that event and wire up:
// wiring:
Matchbox.ready -> YourComponent.ready;
And in your module:
module YourComponent {
provides {
event result_t ready();
}
}
implementation {
event result_t ready() {
// Now the file system is ready to go
}
}

Subject: [Tinyos-help] Way of knowing when file system is ready?
Hi,
I noticed that my first file read fails after reset. The reason (most
certainly) is that the file system is not ready that quickly after reset.
Is there a sophisticated way of checking when the file system has come up?
Other than wasting some time (tried that and it works) or retrying a few
times?
My application checks for a configuration file on startup, and if one is
found, acts upon the data inside. The problem is, if I take a fresh mote
which hasn't been configured, I cannot tell if "FileRead.open" fails due to
missing files or some other problem.
My guess is, I should check the return value but I couldn't figure out the
appropriate FS_ERROR_XXX definition.
Thanks,
Harri
