MC57xxPSIA-TAS5727 No audio output

Other Parts Discussed in Thread: TAS5727EVM

Hi,

    I am feeding AUDIO signal into the MC57xxPSIA and I can confirm there is signal going in, but no output from amp.

I have installed the software on WIN7 and I am able to run the GUI fine. But the problem is there is no output/sound from TAS5727EVM [OUT-AB or OUTCD]. The MC57xxPSIA is not drawing current.

Now after setting the desired values and after the 'CONNECT' command is given, I am able to see this error on the output window


Requested component (BQ3) not foundRequested component (BQ3) not found
Target Connected.
Setting EVM state...Done.

 

I could read 0x00 = 6C and also able to change all channel volume as well.

Jumper's JP-2 & JP-3 on the MC57xx PSIA board is 'IN' and also Jumper JP-4 is updated to connect Pin's 1 & 2.

How could I check whether it is the chip problem or software problem?

 

Regards,

K S Surya Kumar
