* finding significant enough amount of leaked sources
or documentation
and/or doing the reverse engineering required to understand how to talk
to the DSP and/or related peripherals
I have looked through leaked sources for mtk6260 and think there may be enough info tgere,
but I lack deep gsm knowledge so maybe I am deceived.
* finding the time to work on the protocol stack
beyond classic 2G which
is currently implemented in OsmocomBB.
This is the work I intend to purse. Slowly I'm afraid.
