V5.x porting guide or prototypical example?

[groups at chichak.ca]

Thank you Seb and Joel.

I’ll do it. 

One of our customers Flock Audio (flockaudio.com) has a product on the market, PATCH, that uses an STM32F767 and RTEMS. The product is a replacement for a professional audio studio patch bay that is used to route microphones, instruments, compressors and the sort. The Flock unit is a digitally controlled unit but the audio signal path is completely analog. Instead of using 1/4” mono patch cables, we do the patching of inputs to outputs using a crossbar multiplexer  controlled by the processor.

The processor is overkill, and is under clocked to <100MHz for ease of FCC compliance, and uses USB to talk to the desktop app. Future versions will use ethernet, so I’ll have to figure out how to get a network stack going on the ‘767.

Thanks again for the pointers, and sorry to post this in the dev list, I was aiming for the user list but Mail decided otherwise.
