Hi everyone,
My company is using https://www.myzr-tech.com/system-on-module/nxp-som-module/i-mx-8m-mini-som-module.html and upgrading the Yocto nxp to 5.10.72 (hardknott) to support Linux kernel 5.10.72.
And we based on https://github.com/murata-wireless/meta-murata-wireless/tree/imx-hardknott-drogon to bringup the wlan driver. The schematic as below:
I get the following error after bootup.

};I checked my /lib/firmware/cypress/ folder as well,
And /lib/firmware/brcm folder as well,
Could someone please help me to understand if anything is missing? Your help is much appreciated.
