Tool/software:

Hi,

I am new to the TI smart amplifier ecosystem. We are trying to evaluate the TAS5825EVM and have also bought the PUREPATH-CMBEVM Motherboard

We have installed the PurePath Console v3.2.1 in our windows 10 PC

Installed the EVM GUI SW -TAS5825M GUI for PurePathConsole 3

Connected the Motherboard to the PC

Applied external 5V to PVDD on the EVM daughter board

Connection is succesful but I am not able to do the system check - hardware check always fails and says download unsuccesful. We only have one PurePath Motherboard and one TAS5825 eval board

The Motherboard is detected by the PC and below are the details of the windows driver that is in use.

Kindly Help

    hi，

    you have no need do that system check. 

    connecting the evm board, just use the tuning and audio processing directly.

    The external 5V was not sufficient to turn ON the amplifier. Increased it to 6V and it is now able to play audio

    Also the system check download is working

    Although, now it says audio sound card sampling frequency is not 48kHz

    All the tuning seems to work fine. Should I change sound card firmware with the one found from here

    SLOC305 — Audio Firmware (TAS1020B) V0354

    Thanks,

    hi,

    when we use the evm, there seems no this firmware request. but i think you can take a try.

    if you cannot play the audio, is that possible you haven't chosen correct input for the evm?

    tks
