TAS2563: TAS2563 Calibration fail.

Part Number: TAS2563

Hi Team,

I am calibrating the tas2563 amp. but It is always getting failed.

Using the below command and attached the ftcfg file got from the TI.

factorytest -t 25 -c TUNINGMODE-TEST_TAS2563.ftcfg -v

and below is the result.

And i tried to access PPC3 tool but it is not showing any apps.

Please let us know what extra steps need to be followed for FTC.

Also referring the below docs

TAS2563 End System Integration Guide, and TAS2555, TAS2557, and TAS2559 Factory Test and Calibration Guide

Thanks.

  • TO-SHENGHAO-2563.7zThis is the ftcfg file using currently for the FTC

  • Hi, Raghu,

    Our team will take a look at this and will provide a response as soon as possible.

    Best regards,
    Luis Fernando Rodríguez S.

  • Hi Raghu,

    I'll check about FTC results along with our driver support team.

    Regarding PPC3, can you share the account you're using to log in? (you can send a private message with the address) I can check what are the apps you have been granted access.

  • Hi Raghu,

    You didn't had access to any of the software tools, I have granted you access to PurePath Console as well as TAS2563 app.

    The FTC results show 0's for all values, it would seem like the device is not configured correctly. Have you tried to initialize the device using bin file? Is it working correctly?

  • Hi Ivan,

    PPC3 is Still not able to load the any apps.

    what do you mean by "device is not configured correctly" ? we have used the .bin file shared by TI. and audio is working.

    Thanks

  • Hi Raghu,

    Are you using PPC3 within a corporate network? Can you confirm you're using w10 system? We've seen some cases were corporate firewalls are not letting PPC3 connect to the download servers. In that case is there a chance you can use a different network?

    If audio is working OK, then perhaps the recording path is the one having problems during calibration. Can you share schematic and layout files if possible to discard any hardware issue?
