How to use 6GHz wifi? I use AW693 / imx8qmmek / YOCTO=6.1.55-2.0.0.

Even though regulatory.db is updated, but 6G is not enabled.

The environment is as follows.

I checked . The database is the same as 2023.9.1 as shown below.

root@imx8qmmek:/lib/firmware# md5sum regulatory.db /tmp/wireless-regdb-2023.09.01/regulatory.db regulatory.db.p7s /tmp/wireless-regdb-2023.09.01/regulatory.db.p7s

 Are there any problems? If additional logs are required, please provide instructions.

I don't think wifi drivers etc. are relevant at this level yet.
