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

Wow,
This is so kind of you !!
I have very specific requirements.
1. What is the image format, which this bootloader can read from eeprom and
load into mote program memory. (Any function which can convert SREC to
bootloader suitable
format?)
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.
2. How to configure bootloader. i.e. how to tell this bootloader from
which address to lift the image and load it in mote program memory,
before resetting the mote.
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.
3. How to install this bootloader?
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".
4. Can I use it for my purpose ?
Yes, you can. :-)

Thanks a million.
Could you please tell me, if any raw documentatoin
exists within the code itself, in the form of
comments. Which source code files of DT2 contain these
things? Timebeing, I will try to reverse engineer it
for myself.
The bootloader is locate in tinyos-2.x/tos/lib/tosboot and as I said is
heavily based on the Deluge T2 from tinyos-1.x. The most interesting file
is probably TOSBootM.nc. I'm quite busy for at least one more week but if
you indicate me in which part of the bootloader you are interested I can
try to explain it over email. :P

Hi,
I am interested in Deluge T2 Bootloader.
As my M.Tech. Thesis, I have designed and am implementing
an algorithm for code dissemination and remote reprogramming,
which is slightly different from deluge.Hence i require the details.
I'll add a section in the Deluge T2 manual about this as soon as I get a
chance.
