TLV320DAC3101EVM-U: Codec Control Software Not Detecting EVM

Part Number: TLV320DAC3101EVM-U


Tool/software:

Hello,

When I connected my TLV320DAC3101EVM to my laptop to try using the codec control software (for which I downloaded and extracted the SLAC366 software downloaded from here: https://www.ti.com/tool/TLV320DAC3101EVM-U), the software doesn't detect TLV320DAC3101EVM for some reason. I haven't done anything to the EVM yet nor changed any of the jumpers. Any ideas or alternate software to fix this issue?

I am using Windows 11, and the jumpers and board I have right now look like this (the LEDs lit up too which, from what I understand, means successful connection to my laptop):

In addition, if the codec control software is not detecting my EVM, I could also provide I2C and I2S data directly from my master chip instead of from the codec software. I was wondering if I could directly connect these signal wires to the test points 1 through 7 on the EVM board, since I do notice there is a TAS1020BPFB on the EVM as well which also connects to these I2C and I2S pins, and I was worried that there might be some signal conflicts and interference. In addition, I was curious what TAS1020BPFB is doing exactly on this EVM.

Thank you,

    Hi Jiahe,

    One simple thing to try is to run the GUI in administrator mode. The LEDs do indicate a successful connection from the EVM side but not necessarily the PC side. Can you check the device manager for the status of the EVM? Let me know if any errors appear.

    Best regards,

    Hi Jeff,

    Thanks for your reply! Running the GUI in the admin mode wasn't working for me. I did see an EVM in my device manager as shown below, and it seems to be working properly. 

    In the meantime, I was thinking about removing the TAS1020BPFB and EEPROM from the EVM to supply I2C and I2S data externally. I was wondering if it is necessary if the Codec Control software isn't detecting and using the EVM.

    All the best,

    Hi Jiahe,

    Okay. You can definitely use I2C without removing anything on the board, but you will have to lift the TAS2010B pins if you want to provide external I2S. Before you remove anything, let me double check on my side to confirm that this GUI is supposed to work with Windows 11. If you do have a Windows 10 machine nearby I would try it on that and see if anything changes.

    Thanks,
