Kernel log level appears to be locked at 3. This Passing Additional Kernel Parameters | NVIDIA Docs says to change this file:

drive-foundation/virtualization/pct/<platform>/linux/linux_storage_qspi.cfg

Where my platform is p3710-10-s05 - which is not mentioned on this page - but this file does not exist.

The files that do exist in this directory have no mention of loglevel and the only mention of os_args is in

linux-linux/linux1_storage_emmc.cfg
linux-linux/linux2_storage_emmc.cfg

In kernel config I have set:
image

so I would expect this:
image
to be 15 7 1 15 or similar.

What is the correct file to modiy to change the log levels so that the loglevels obey what I specify in the kernel config?

We will review the documentation and get back to you.

Does the command work for you as a temporary solution?

$ sudo sysctl -w kernel.printk="15 7 1 15"

That sets things, but not for boot. Regardless, the real solution is to add -DDEBUG to the Makefile of the module(s) of interest.
