How to config the ssi as i2s salve

[vecio_lin]

Dear Nxp community,

i got a problem when i trying to bring up a audio chip zl38102 in imx6solo with newest Kernel 4.14.

i config the spi bus,and the community with the chip is okay, and the sounds card is already registered. and config the ssi1 as i2s-salve.

i change the Kernel config let it support the old oss. so i test the audio in the console.

cat wav > /dev/dsp

but it is no any output from the i2s.

how can i deal with that?

by the way, the audio chip is work well in the imx6 solo with imx 3.10.

Hi Vecio

one can try to follow Chapter 16 Porting Audio Codecs Porting Guide

included in Linux L4.14.98_2.0.0 Documentation

also may be useful to check Chapter 7 Audio Linux Manual.
