 I am learning the  usb3014  

Download the demo the demo UartLpRegMode

the Teraterm print nothing

 the cursor flash very fast  but print nothing  even I input from the key.

I change the software for the uart  use the serial port utility

the uart read  all "*************************" very fast 

when I change to the HEX , I get a lot of"00 00 00 00 00 00 00 "

so why?   Does the demo has some bug  on  the superspeed explorer kit?

How  i can  fix it?


I can read the message from the uart  by use other demo  so  the uart should be ok.

Hey Liu

The firmware is well tested and there is no such bug reported. I checked the performace right now to verify and no problem here.

Make sure that you are using the default firmware without any modificaiton .

Make sure that the baud field in the COMM terminal is 115200 baud. I used tera term to test, maybe you can also give it a try
