Title: Using Cypress FX2 to determine host power capabilities
Post by: nburkitt on April 01, 2016, 09:38:57 PM

Is it possible for the Cypress FX2 device (on a TE0630) to determine if a connected USB device is a Charging Downstream Port (CDP), Dedicated Charging Port (DCP), or Standard Downstream Port (SDP)? If so, can someone suggest where in the FX2 firmware to start looking?
Thanks,
-Nick

Hello,

You can found FX2 firmware sources at https://github.com/Trenz-Electronic/TE-USB-Suite/tree/master/TE_USB_FX2.firmware
There is no CDP/DCP detection in current version

Hi Oleksandr.

Thanks for the reply. I have the FX2 firmware already - I'm hoping for some guidance on where in the firmware such a determination might be made. Or at least where to start looking without first becoming a USB expert. :'(
Thanks again,

-Nick
