I don't know about that port, but in this case they were distributing a derivative of GCC. Whatever their backend was, it was then infected by the GPL (I guess that's the only reason why you could order the source code for $200 or something like that). Somebody seems to be maintaining the old compiler, I saw it for FTP somewhere, and I actually fetched it. BTW, their new compiler doesn't even optimize for DSP (or at least, you can't enable it, because it generates bad code), so if someone says gcc would not be good enough, don't believe it. They pumped up the major version number one notch, but it's really 0.x stuff. To make things worse, we were developing using some prerelease chips (great to have that, nothing else would cut it). When the time came, overlaying would not work. People here spent a lot of time looking at the software, and in the end it was a silicon bug: the external memory interface would not work. You should definitely not use two broken things at the same time. Fernando D.
