AFE4300 EVM-PDK Connection Error?

Eric Forkosh

Other Parts Discussed in Thread: AFE4300, TUSB3410

I'm trying to get my AFE4300 EVM-PDK working, but I'm having some strange troubles!

My Setup

I've carefully followed the Development Guide, installed all the software, but I can't seem to get connection working with the AFE4300 GUI.

I see the correct "TUSB3410 Device" appear in the Device Manager under COM Ports.

Problem

When I connect the AFE4300 EVM-PDK to USB, the green LED on the board turns on and on the LCD screen it shows AFE4300 .. scrolling across the screen. Then the Green LED turns off and on the LCD screen all I see is "XXXX".

Attempted Solution

I've double checked that the drivers were properly installed.

I checked for missing components or bad solder joints on the board and it seems ok.

What else can I try? What would cause such an issue?

Thanks!

Thanks Amy!

If it helps you, I also tried:
1. Reinstalling the drivers and software
2. Installing software/drivers and connecting EVM-PDK on a different computer
3. Verifying the EVM-PDK pin connectors were securely connected

Still no luck. Still the same problem.

Looking forward to some suggestions on what to try.

Hello Eric,

Could you attach the error message you get when you start the AFE4300 GUI?
Are you able to run the GUI in simulation mode (without connecting the EVM to the PC)?

Thanks for the reply.

Attached is the error message

GUI runs fine in simulation mode without the EVM connected to the PC.

I understand you mentioned that you are able to see the correct "TUSB3410 Device" appear in the Device Manager under COM Ports.
Could you still attach the Device Manager view of the COM ports?

COM50

Thanks!

Could you manually change the COM port from 50 to 6 (for example)?

No dice. Still the same error.

Praveen,
Thank you for the advice.

Is there anything else I can try? I'm doing this project for a client and I'm afraid that time on my deadline is running out.

Is it possible my AFE4300 EVM-PDK is just defective? Can I exchange it for one that has proven to be working?

Eric,

To find out if the EVM is defective, could you run the tests outlined in the document below?

Thank you for the guide

Unfortunately I get this error, "Unable to Open". I verified that it is the correct COM port and the COM port is not being opened in another terminal.

Please advise

I tried changing it to other COM ports too ( COM38, COM50) - same error "Unable to open Connection"

If it matters, I've used USB-Serial devices before without any problem whatsoever. Heavy user of the FT232 USB to Serial IC manufactured by FTDI.

Thanks

You may want to try again after restarting your PC.

Restarted computer. Same error

Its weird because obviously the USB chip is working because the device is identified on the system. And obviously the microcontroller is working because it is displaying "XXXX" on the LCD screen and scrolls "AFE4300" on the built in LCD screen on power up.

Thanks for the help so far, looking forward to getting this thing working.

Just tried it on a third PC with Windows 7 and it works!

I will play with reinstalling and looking at firewall settings on my own computer. Any tips will be appreciated
