Original question:

AUDIO-AM275-EVM: Couldn't boot up with AM275-AWE-SDK_11.01.16.06

AUDIO-AM275-EVM: Couldn't output TDM communication wave form AEC1 with AM275-AWE-SDK_11.01.16.06

Part Number: AUDIO-AM275-EVM

Tool/software:

After new AWE SDK(AM275-AWE-SDK_11.01.16.06) was available, I built it with Multi-Zone Audio config and was able to check Audio Weaver working by SD card boot.

But I cannot observe TDM communication output wave form AEC1 with oscilloscope.

I assume that the system configuration will be as follows.


I don't have TAS67CD-AEC, so I will check with the AUDIO-AM275-EVM alone.

    Hi Taku,

    Have you enabled AVB for the AEC to work? The AEC will output the audio which comes from AVB talker.

    I am sorry, I am little confused, do you not have the AEC? If so, how are you testing the audio out?

    Thanks,

    Hi Shreyansh-san,

    Thank you for your reply.

    I didn't have AVB enabled, so I'll try it out after activating AVB.
    FYI, I expand the build config when I experimented.

    I have an AEC connector, so I don't connect any devices, but wire through the connector and observe with an oscilloscope.
    Eventually, we are thinking of expanding to A2B.

    This is an activity to get hints for solving the following problems:
    AM2754-Q1: Based on AM275-AWE-SDK_11.00.00.17, adding MCASP2 does not allow TDM communication from AEC2 to external devices. - Processors forum - Processors - TI E2E support forums

    Hi Shreyansh-san,

    I tested the case without AVB and the case with AVB and summarized the report.

    I was only focusing on ACKLX and AFSX, but when I observed AXR0 as well, it seems that this waveform was output.
    It's a problem that ACKLX and AFSX are not being output, isn't it?
