Hello @Megane2077,

Thank you for contacting Intel Embedded Community.

Just to mention, Apollo Lake family is no longer actively supported.

I tried looking into your issue but didn't find something that may be of help. I'm sharing the link to the Apollo Lake documentation, maybe you can find something useful from there.

Also, being Yocto, you can try setting a new image again with the latest updates, could be worth to try.

Best regards,
