Running FreeCalypso Magnetite firmware on the Neo Freerunner
============================================================

As explained in the Modem-configs article, we currently have 3 different modem
fw configurations which differ in the degree of deblobbing.  The classic
configuration is exactly the same as leo2moko from 2013; the l1reconst config
rebuilds most of L1 from source, but our L1 reconstruction is so accurate that
there will be no observable difference in behaviour.  The hybrid configuration,
however, is quite interesting in that it is a new major development, as major
parts of the fw have been replaced with an entirely new version from another TI
program.

The deblobbed TCS2/TCS3 hybrid configuration is intended to be our direction
going forward, but it will need extensive testing and debugging before it can
replace the classic/l1reconst configs (or older mokoN/leo2moko firmwares) for
production use.  The principal developer's intent is to build our desired
FCDEV3B hardware and do this testing and debugging on that board, but it can
also be done on Openmoko devices.

Given the current state of the remains of what once was the Openmoko community,
I (Mychaela) do not feel like doing any significant work on this platform;
instead I would rather build our own FCDEV3B and leave Openmoko behind.
However, if anyone else feels otherwise and would like to play with our
TCS2/TCS3 hybrid modem fw on Openmoko hardware, you can build it like this:

./configure.sh gtamodem hybrid
cd build-gtamodem-hybrid; make

Then after enduring the very slow build, you can flash it with fc-loadtool:

loadtool> flash erase 0 0x250000
loadtool> flash program-bin 0 fwimage.bin

If you are brave enough to do the above, please let us know how this new modem
firmware fares when driven by QtMoko or SHR on the AP - it would definitely be
an adventure!
