Hi!
Because I didn't update the manual yet I'm also forwarding this to the
help mailing list.

The format of the Deluge T2 binary files is this:
* metadata (128 bytes): the fields are:
o uidhash (4 bytes)
o size (4 bytes)
o number of pages (1 byte)
o reserved
o CRC over the above 4 fields (2 bytes)
o appname (16 bytes)
o username (16 bytes)
o hostname (16 bytes)
o platform (16 bytes)
o timestamp (4 bytes)
o userhash (4 bytes)
o padding up to 128 bytes
* CRCs of all the pages (128 × 2 bytes)
* data
The data is split in pages of 1104 bytes (48*23) and one CRC is computed
for each page.

You can use the NetProg interface for this. It's in
tos/lib/net/Deluge/extra. In the same place is also NetProgC, the
component that implements the NetProg interface.

The bootloader is in tos/lib/tosboot. If you put TINYOS_NP=BNP in your
Makefile then it will be automatically installed when you do a "make
install".

Yes, you can. :-)
