175 land of blobs and proprietary build tools. 175 For those who require or desire a firmware version that is completely free of
176 any blobs and builds with a FLOSS compiler, we now have a new experimental
177 firmware project called FreeCalypso Selenite:

181 FC Selenite is based on FC Magnetite (just the modem functionality, no work-in-
182 progress phone UI, and only the hybrid code version), but it uses the new
183 full-source version of Nucleus and our reconstructed versions of OSL and OSX,
184 and it offers the option of building either with the original TMS470 compiler
185 or with gcc. The gcc-built version also uses entirely new implementations of
186 all assembly components and linker script magic, as the two toolchain
187 environments are entirely different in this regard.
188
189 This new Selenite firmware is expected to fully supplant our earlier and now
190 completely unmaintained Citrine fw (our first attempt at gcc-built fw), but it
191 is still highly experimental: as of this writing, GPRS does not work at all in
192 Selenite-gcc (Citrine does not have any GPRS support either), and even the
193 GSM-only config with GPRS disabled exhibits some intermittent glitches. Thus
194 the stable production fw is still TMS470-built FC Magnetite for the time being.
