Texas Instruments finally decided to release free-to-use versions for Linux of their C/C++ compiler for the c54x DSP series (for open source projects at least).
This DSP is found in TI’s TMS320 family (dreaded chips, known mostly in our communities for their total lack of public docs).
In Rockbox terms, this exciting news opens up the possibility for easier coding for the targets that use the DM320 series, which currently is the Olympus M:Robe 500 but may include other players in the future.
For your convenience, here’s a link to the actual TI license and the 12MB tarball (hosted on my site). The tarball contains a binary that installs 86 files occupying 31MB.
The compiler and more details can be found in the Neuros blog.
