TLV320AIC3101EVM-K: Drivers on Windows 10

Hello Kevin,

Apologies for the delayed response. 

The PC recognizing the device as USB-MODEVM is a step in the right direction. Just a couple of comments/questions:

1. SW-2.1 is A0. Do you mean A0 or A1? Why was this switch changed?

2. With SW-2 in default state, D2 should light up. Is D2 only lighting when you switch A0 or A1?

3. The power LEDs look fine. 

Regards,

Aaron

Hi Aaron,

You're right, my mistake; I should have referred to SW-2.2 (A1). I think I slipped back into zero-indexing....

The pin state out of the box was:

• SW2.1, A0: ON
• SW2.2, A1: OFF
• SW2.3, A2: ON

When I plug in the device in this configuration, D2 does not light up.

I found that if I change the pin state to:

• SW2.1, A0: ON
• SW2.2, A1: ON
• SW2.3, A2: ON

then D2 lights up. Is that the correct solution?

Thanks for the confirmation of the power LEDs.

Do you have other ideas of things I could try? I wonder if it's a driver/Windows 10 issue.

Thanks,

Kevin

Hello Kevin,

No worries... it happens!

Default SW-2 should be SW2.1-2.7 should be ON( switched to LO) and SW2.8 should be OFF (HI). Please take a look at the below image for reference. Can you also send a picture of both the TLV320AIC3101 EVM and the USB-MODEVM so I can take a look?

Regards,

Aaron

Hi Aaron,

Pardon the delay - it took me awhile to track down a good camera.

The position in your photo is not what I saw after unboxing, but it is the same position that I arrived at.

Anything else look out of sorts?

Detailed pictures of my current setup are below.

Hi,

Following up -

• Do you have any feedback on the hardware settings?
• Do you have any suggestions for configuring Windows 10 software/drivers?

Thanks,

-Kevin

Hello Kevin,

Apologies for he delayed response. The hardware images you sent show both the daughter card and the Mother Board in default state. I have a couple of comments/questions regarding the next steps:

• After installing the drivers did you restart the PC?
• Please disable any antivirus software and try connecting back to the GUI. It is possible the antivirus software may be interfering.
• Can you verify in the Device manager that the USB-MODEVM is also showing up in "Sound, Video and game controllers"

We are currently trying to replicate this issue here so we can try and find a solution. I will update you soon. 

Regards,

Aaron

Hi Aaron,

Thanks for checking the hardware.

To answer your questions:

• Yes. I rebooted again just to be sure, but there is no change in behavior
• Antivirus should be disabled. It had no effect.
• Yes, I see it there. See screenshot

Is there any other information that I can provide? Perhaps I didn't install the driver properly?

Thanks again,

-Kevin

Small update - I managed to find a Windows 7 and install the program and driver on this machine. It behaves almost identically to the Windows 10 machine; the program and driver install, the USB device articulates under both "NI-VISA USB Devices" and "Sound, video and game controllers", but the program says "Connect USB" when run.

HI Kevin,

Thanks for that update. It sounds like a USB-MODEVM firmware issue. We have not seen issues like this on Win7. How old is the board? Was it recently purchased? And are you US based? We can get you a known working board for you to try out. 

Regards,

Aaron

Hi Aaron,

The board is quite new, from my perspective; we ordered it last week (Feb 12 2020).

Yes, I'm in the US on the West Coast. I'm happy to try a known-good board.

In the meantime, do you have any other troubleshooting ideas on the Windows 7/10 driver? Perhaps a mistake that I am making?

How can I move forward getting a known-good board?

Thanks again,

-Kevin

Hi Kevin,

Is it alright if I contact you offline? I will ask for shipping details and other information needed to send you a board. In the meantime, I cannot think of any other debug steps for you to try.

Regards,

Aaron

Hi Aaron,

Please do - I'll wait for your message.

Thanks again for your help,

-Kevin

Note for future reference - I received a base board but the program still exhibits the same behavior.

I've tried Windows 10 and also a Windows 7 system.
