Makes total sense if it provides enough bandwidth. There are some
other options that are based off of the FX2 USB2.0 chip that are
common in low cost ($10) 8ch 25MHZ logic analyzers as well. As you
said it's a block with a few input pins, FIFO, and a usb interface, so
if it works, sounds good
If you want high-speed io to USB the FX3 is probably one of the best bets.
You see it frequently used on logic analyser and software defined radio
boards between the USB and the FPGA.

There are several EZ-USB
Thanks, Brennan and Petr, for the recommendations.
At this point, I am only trying to ascertain if there are a few people
interested in participating in such a project. I think it is more that
I can consider to do alone so any further steps would require some
interest in the development itsel
Why not use the ETM?

Hi, List,
I have been contemplating a NuttX-based Open Source project today and I
am interested in seeing if anyone is will
My two cents... I would definitely make use of some existing frontend for
tracing visualisation. Something like this in case of lttng -

Trace Compass seems to be a fairly complete solution for visualisation -
