|Good question, Real Time Platform I believe.. You can download it for free from QNX.com|
I just replaced the Tiny tcpip stack in Audrey with the regular tcpip stack from RTP 6.1. Performance increases substantially, so I believe I'm there. Would be convenient to have devu-ohci from the 6.0 version to compare, since the USB setup still needs some more CPU power than before. Don't know if this will effect MP3 playing, or anything at all.
The extra you have now is no more hacking necessary for USB network cards, implement the drivers for any RTP supported USB device and there you go.
A thorough study of the QNX Utilities Reference for io-net, devi-hirun and more is mandatory, if you want to install devices...
I will try to have a small update available for the version 3 image and make this totally new image with USB support available as a separate item by this Friday. Not a single Kojak app in this image anymore, but still int/ext modem and everything you had before, including working buttons. Support for this new image has to be a group effort here. Don't expect much from me for this one, it's too complicated. What you do get is a small manual in Adrey to point you in the right directions. No new web site.
