fc-shell TCH DL handler: add support for CSD modes
TCH DL capture mechanism in FC Tourmaline firmware has been extended
to support CSD modes in addition to speech - add the necessary support
on the host tools side.
It needs to be noted that this mechanism in its present state does NOT
provide the debug utility value that was sought: as we learned only
after the code was implemented, TI's DSP has a misfeature in that the
buffer we are reading (a_dd_0[]) is zeroed out when the IDS block
is enabled, i.e., we are reading all zeros and not the real DL bits
we were after. But since the code has already been written, we are
keeping it - perhaps we can do some tests with IDS disabled.

You are looking at the source for the TIFFS In Vitro Analyzer utility. You may have downloaded it either as a separate package or as part of the larger freecalypso-sw suite. See TIFFS-Overview (in ../doc if you are working with the full freecalypso-sw source tree) for a general description of what TIFFS is and why it matters. The utility contained in the present package runs on a general purpose GNU/Linux (or other Unix) host and enables "in vitro" examination of Flash File System images read out of TI-based GSM devices. Using this utility, you can list the directory and file content of an FFS image, cat any individual file in the FFS, or extract the complete FFS content into your regular Unix file system. Some "forensic" operations are also supported: by listing the inode array, one can deduce the order in which the present FFS content got created, and see what files have been overwritten or deleted in the span of still-visible history. One can then cat the old byte content of those overwritten or deleted files, if those data chunks are still in the FFS image (i.e., if the flash sector in question has not been reclaimed yet). Compilation and installation are straightforward: run 'make' to compile the source; you should get 3 executable binaries named tiffs, mokoffs and pirffs; then run 'make install' as root to install them in /usr/local/bin. The binary named tiffs is the main program; mokoffs and pirffs are wrappers that simplify the most common current use cases. To install somewhere other than /usr/local/bin, edit the INSTBIN= setting in the subdirectory Makefiles. You will also need to edit tiffs-wrappers/installpath.c accordingly, as the mokoffs and pirffs wrappers are designed to exec tiffs by its absolute installed pathname. See Usage for the usage instructions.
