Dear all,

there is trouble by configuring the TUSB 320 evaluation module from Texas Instruments which help to evaluate the small device which operates for usb type c configuration logic. I am not receving the V_bus voltage, that being said, when the module is powered, I have 0.4 Volts V_bus voltage. The module is configures as UFP device without any Power delivery mode.


Currently I'm using the TUSB320EVN evaluation module, and we are planning to use it in our product as a hardware in between the Type-C USB and  our USB-2 Device connection.

I have powered-up the module with the 5.0 Volt barrel connector and there is a constant 5.0 Volt power applyed to module. The R-12 resistor is de-soldered and the switch is set-up  [ 1 0 0 0 0 0 0 1 ] , where 1 = ON and 0 = OFF.

The USB type - C J7 connector is not connected. When I attach the USB J7 connector to my pc, nothing happens, the hardware is not being recognised. There is no any kind of device recognized by my PC.

At this point I have no idea, why it is not recognzed by my pc and what other settings I am missing out.

So nothing to do with AVR or Microchip / Atmel.


Best to keep to the TI Forum - where you have actual TI people to help!


and one reply already.



Top Tips:

  1. How to properly post source code - see: https://www.avrfreaks.net/comment... - also how to properly include images/pictures
  2. "Garbage" characters on a serial terminal are (almost?) invariably due to wrong baud rate - see: https://learn.sparkfun.com/tutorials/serial-communication
  3. Wrong baud rate is usually due to not running at the speed you thought; check by blinking a LED to see if you get the speed you expected
