Hi all,
To be frank I'm a huge supporter of Free Software and the GPLv3, but
regarding TI's code I tend to agree with Mychaela: it's more likely
than TI will agree to a slightly permissive license to use the source
code rather than the GPL. Since we may only get once shot at this,
it's possibly
Hi all,
As you may know, TI's toolchain, when building a firmware,
usually replaces the original strings with integers, and places
the strings in a file called "str2ind.tab". This has the
advantage of saving flash space, however without this strings
file the trace output is much less useful.
Hi,
After more testing, it seems (apart from the AMR bug and the deep sleep

Hello Ajay,
Although I have limited experience with osmocom-bb, I think you do have to
use the chainload option to load the layer1. This is really due to a limitation
in the bootloader, expecting 1003 or 1004 which imposes a limitation of the
size of the code you can execute this way (below 16K).
Hi Mychaela,
