148 Magnetite-specific notes
149 ========================
150
151 Just like FC Citrine, FC Magnetite currently supports only AT command operation
152 via fc-shell; the C-Sample UI hack we have built earlier in tcs211-c139 has NOT
153 been incorporated into Magnetite - at least not yet.
154
155 When compiling our Magnetite firmware for the C139 target, you will need to
156 select the l1reconst configuration - it is the only currently available
157 configuration that works on this target. Therefore, you configure.sh command
158 should be:
159
160 ./configure.sh c139 l1reconst
161
162 See the Compiling write-up for more details.
163
164 Because we have not deblobbed the G23M firmware component yet (the l1reconst
165 configuration uses G23M binary blobs from TCS211/Sotovik), your Magnetite fw
166 build will include FAX_AND_DATA and GPRS functionality. In the FreeCalypso
167 environment where we are not doing WAP or MMS this functionality can only be
168 exercised on targets that bring out a classic modem UART with the classic AT
169 command interface to the external host, but Mot C139 is not one of those
170 targets - hence on the C139 all FAX_AND_DATA and GPRS code is nothing but dead
171 weight. We will only be able to remove this dead weight when and if we fully
172 deblob all of L1 and G23M, so it will be a while before we get there, and we'll
173 have to carry the dead weight until then.
