Hello,
on http://focus.ti.com/docs/toolsw/folders/print/linuxdvsdk-dv.html I find that a new DVSDK is available:
Effective Oct 2010 - Linux DVSDK v4 has been released. For DaVinci devices not listed above, search TI.com for your device part number; This product page will have a link to your current DVSDK.
but where do I get this new version? Is it for all Davincis (I'm mostly interested in the DM355) or only for some devices?
The page for the DM355 at least just links to the page cited above. No other Davinci part, that I checked, incorporates a link to the DVSDK v4.
Best regards
Siegbert
