Re: Deluge T2 and iris motes

Yann,

Thanks for reporting this issue. A quick recap, just for the record: a
recent change to chips/at45db/BlockStorageP.nc that allowed for
non-power-of-two page sizes broke deluge/tosboot on the iris and micaz
(probably other platforms, too), because deluge and tosboot were
expecting the page size to be 256.

For now, I reverted back to the old chips/at45db/BlockStorageP.nc,
which assumes that the page size is a power of 2. Deluge/tosboot needs
to be fixed post 2.1.2. I'm posting a google code issue, as well.

Janos
