}; After moving to kernel 6.18.20 SAI3 is not probing and I got no sound-card. The boot log shows: platform sound: deferred probe pending: asoc-simple-card: parse error What changes in the DT syntax from kernel 6.6.52 to 6.18.x? I didn't find anything relevant. How can I investigate the parse error? i.MX 8M | i.MX 8M Mini | i.MX 8M Nano Linux Yocto Project Re: asoc-simple-card: parse error after upgrading to kernel 6.18.x Hello,
Could you please share your dmesg log?
Best regards. Re: asoc-simple-card: parse error after upgrading to kernel 6.18.x Hi Jorge, dmesg log and running device tree (./dtc -I fs -O dts /proc/device-tree > /tmp/running.dts) attached. Re: asoc-simple-card: parse error after upgrading to kernel 6.18.x Hi, I have moved one step forward. After enabling the kernel configuration option CONFIG_IMX_AIPSTZ=y, the sound card device is now available. Because sai3 node is a sub node of aips5 I also had to enable aips5 in my devicetree: &aips5 {
status = "okay";
}; Now I got the following error messages: [ 13.081746] fsl-sai 30c30000.sai: ASoC error (-110): at snd_soc_dai_hw_params() on sai-tx-rx
