How to config the tdm port on nrf54lm20

[huma]

I want to try the tdm function on the nrf54lm20 dk.

But i have encountered problem in the first step.

I do not know how to add the tdm port and assign the pin.

Whin i enable the tdm in the device tree, there is nothin in this page.

only this code generated in the overlay files

I try to assign the pin:

But seems invalid...

Can you help me to pass the first step?

Thank you very much!

Here is a simplistic sample a colleague of mine made, where I added a overlay example for nRF54LM20A:

Please note that you cannot use P2 for TDM purposes:

Hello Håkon

It works!

Thank you very much!

But the lrclk seems not very accuracy when it is 44.1K

When i config it to 48K, it will be more accuracy:

Do you have the same problem?

Thank you again!
