IMX6 DualLite sound card wm8960

shinnn — Fri, 30 Jul 2021 08:57:59 GMT

Hi All,

I am using iMX6 DualLite. I want to use wm8960 on imx6dl

But currently the default BSP audio on imx6dl uses wm8962 and uses ssi interface

I have tried porting wm8960 of imx6ul-14x14-evk.dtsi to imx6qdl-sabresd.dtsi,.dtsi, but it didn’t work.

In addition, there are also reference forums and porting methods on the Internet, but they have no effect, as follows

Hi b45499,

It still can't work, do you have any other ideas?

I'm working on i.MX 6DualLite custom board connect the wm8960 with ssi interface.

Can you share your imx-wm8960.c and wm8960.c , wm8960.h files?

Below is device tree( imx6qdl-sabresd.dtsi YOCTO linux kernel 5.4.70_2.3.0)
