Hi,
I have a TWR-K64 board and going to do usb test. I am trying to use the demo project "usb_examples-usb_device_cdc_vcom", but I don't know how to set the jumpers. There is a readme.pdf in usb_examples-usb_device_cdc_vcom->bm. I read it and got confused. Please look at the captured picture below. It says, J29 3-4, Remove all jumpers from J19. I did so, but there is no power supply any more on the board. I am wondering, how the internal regulator will output without an input?
Also, 2. Connect the target board to the external power source (the example is self-powered). Dose it mean the TWR-K64 needs an external power supply, say from tower boards? If so, could you please tell me how to set the jumpers to make this usb self-powered to get an external power source? Thank you very much!
Hi Lei Peng
Please refer to my settings,
J29: 3-4
J19: 1-2
Have a great day,
Daniel

Hi Daniel,
I made it running as per your setting. The document misled me. It should be updated.
Thank you very much!
