Other Parts Discussed in Thread: ADS7846
Tool/software:
Hello TI
The version of SDK I use:ti-processor-sdk-linux-rt-am62xx-evm-09.02.01.09
I refer to the following link to configure HDMI audio and find the following error:
e2e.ti.com/.../processor-sdk-am62x-about-the-sii9022-hdmi-audio-problem
Here is my device tree configuration:

There seems to be a problem with the clock frequency configuration, but it works for me on the processor_sdk_08_06_00_42 version.I hope you can help.
