Perhaps more friendly licencing terms similar to this C54x toolchain would be nice to have for our C55x toolchain too. Good point. I had a quite longish discussion with TI DSP OSS support about a year ago. And after some weeks of back an forth the guy said, that they (TI) would have no problem with open source code being developed with this toolchain and even binary versions of the code being redistributed - as long as noone makes money from using the toolchain, I guess. I also explicitely pointed him to this development board exception in the license agreement and his reaction was more or less as long as you use it with TI CPU it is fine, which would be hard not to do ;) Here is the final full quote from Thomas Maughan from TI: --- Nils, I've got quite a busy schedule right now - here's the quick answer. Providing source and binaries that are your work is OK - just don't post the tools themselves. Your posts would only then be useful to those that are equipped with the same Linux DSP Tools which means they've installed and agreed to the license.

Re: TI frees its DSP toolchain for open source apps (?) - linuxdevices
FYI: Just found this news from TI about freeing the DSP toolchain to open source developers, http://www.linuxdevices.com/news/NS4338556106.html http://open.neurostechnology.com/node/1020 I'm not all together sure how this (the Google SoC project) differs from the dspgateway, except perhaps for the choice of DSP. Why have yet another way of bridging between ARM and DSP? Could someone (with more technical expertise then me) comment on this? Please refer my post at linux-omap mailing list. http://linux.omap.com/pipermail/linux-omap-open-source/2007-November/012049.html This is interesting, mainly for the dspfs and the request for more access to the IVA. Thanks for the link. I think neuros link mentions some G-SoC project which should have been merged with dspgateway driver developed mostly by Nokia for OMAP1/2, this way we Certainly it ought to have been, or am I missing something - was it merged? are bringing support for lot's of DM series of boards and setting a playground for DaVinci related processors dspgateway support. I had a look at the DaVinci processor information available from Ti and it seems they don't really want to give much away (probably because this is their current main model line or something like that). We do already have a Linux Ti toolchain ( https://www-a.ti.com/downloads/sds_support/targetcontent/LinuxDspTools/index.html) which is for the C55x only (i.e. is useful to us). I'm not sure the release of another (similar afaict) toolchain for the C54x will make any odds to us (except perhaps that Ti are embracing open source developers :).

Why have yet another way of bridging between ARM and DSP? Either C54x architecture is more limited (no MMU? no space for multitasking core like DSP BIOS?) or this is really quick student hack for G-SoC without deep research for existing alternatives.

Perhaps more friendly licencing terms similar to this C54x toolchain would be nice to have for our C55x toolchain too.
