Hi all, from what i learned, osmocombb provide gsm protocol stack and dsp
signal process code.
So why need to use Ti Calypso/Iota/Rita. Is it possible to run on other
common arm7+dsp chipset?

False. Osmocom-bb doesn't have demodulation or dsp code. It contains dsp
drivers to control the calypso DSP stuff.

See above. All the DSP code, as well as all the dirty details about timing
/ rf path configuration / dsp stuff is completely calypso specific.
If you wanted to support another one, it's possible. But you'd have to
write the equivalent of all the "target" code for your target and it would
talk to the l23 stuff using our l1ctl protocol.

Because a board designed from scratch would cost a 100 euros and a
Calypso phone can be bought for 5.
