USB port mapping

Post by marssystems »

I want to send/receive data to/from an application running on the StartKit using the USB port. How is the USB port mapped to the microcontroller? I cant see any mappings on the port list.

The USB is connected to the on-package USB PHY which is connected to the second tile using ULPI.
This second tile is meant to be dedicated to debugging the first tile (it basically implements the same functionality as a standalone XTAG2 debugger). I'm not saying it is completely impossible to use the USB connection but it certainly isn't straight forward and requires a bit of research.

Thanks for the clarification. I thought it might be something like that. I'm already looking at connecting a USB to TTL board and providing connectivity that way.

What kind of data are you looking to transfer?

Sorry, i mean is this debug or test input/output data, or some product that requires a USB connection?

This is LIVE data, not test data. As the only connectors available on PCs and laptops these days are USB, then the logical choice for data interchange would be USB.

where "LIVE" means what? Real-time?

Yes - real-time data.
