DAC39RF12: Issue Requiring Simulation Mode in DAC39RF12EVM GUI

KIM JASEUNG

Part Number: DAC39RF12
Other Parts Discussed in Thread: TSW14J59EVM, , ADC12DJ5200RFEVM

Tool/software:

Hello,

I am currently using the DAC39RF12EVM board connected to the TSW14J59EVM board with the TI GUI.
According to the User Guide, I have verified the power supply, jumper settings, and clock input, and the GUI correctly displays both the FPGA number and the DAC board type.

However, unless I check the Simulation Mode option, the GUI does not proceed to the next step.
Even though the actual board is connected, it seems that I must enable this mode to continue, and I would like to know if this behavior is expected.

If there are any additional steps I should take—such as installing a required USB driver or changing jumper settings on the TSW14J59EVM board—please advise.

In addition, the DAC39RF12EVM product page on the TI website is currently not accessible, and the part number DAC39RF12EVM does not appear in the search results.
For this reason, I am posting my question here under the DAC39RF12 device.

Thank you.

    Kim, 

    Could you try disconnecting the EVM from the PC, reconnecting it and then waiting about 10 seconds? Sometimes the FTDI driver misbehaves. The fact that two serial numbers are showing up that are identical and one ends with C indicates the FTDI driver may of had a hick-up. 

    Regards, 

    Matt

    Hello 

    I tried disconnecting and reconnecting the EVM as you suggested, but the issue still persists.
    I also tested it on a different PC, and the same behavior occurs there as well.

    For additional context, I am also using an ADC12DJ5200RFEVM. To my understanding, its GUI also communicates over FTDI, and I have not observed any connectivity issues when using the ADC board.

    I have also performed a clean reinstall of the FTDI driver (removed existing drivers and installed the current Windows driver installer), but the behavior did not change.
    Do you have a recommended FTDI VCP/D2XX driver version for this EVM/GUI? If not, are there any other steps you would suggest?

    My OS details: Windows 11 Home 24H2 (Build 26100.6584).

    Thank you for your support.

    Best regards,
    Kim

    Hey Kim, 

    I have seen this error a couple of times on my PC. It seems to be behave intermittently on my pc, which has made it difficult to debug.  It has something to do with the latency in the FTDI driver and we need to fix it on our end. I do apologize for the frustration. When this error does occasionally occur I have found that re-scanning a couple times and potentially unplugging it from the pc and back in usually fixes the issue. It sounds like you have not had any luck?
