[Tinyos-help] ConfigStorageC help

[Dimas Abreu Dutra]

David,
 
 I did the tests and they worked out OK. The green led turned on. While debugging to find out what was going on my application, I discovered that if I changed the size of the volume I was using to store the configuration on the following happend:
    
   256B - The application crashed during the erasure of the log Storage Volume I was using. The program does not respond   
   512B - I can write to the config storage with success but after the commit it does not return true on the valid() command.   
   4096B or more - I get a true return on the valid() command even if it is not valid but cannot get success on the commit() command 
 I think that maybe these results are because I am using a LogStorage and ConfigStorage interfaces on the same program. Does that make any sense? I will do some tests later and try to trace the error source.

Does the ConfigStorage test app work for you? It's in
apps/tests/storage/Config. You probably want to try the following:

  make mica2 install.15 # do a basic test
  # wait for the green led on the mica2 (red means test failed)
  make mica2 reinstall.115 # reboot and check you can read the previous results
  # wait for the green led on the mica2 (red means test failed)
(see the README.txt for more details)
