hello rlatae123,
did you meant the warning message has reported as below?
module verification failed: signature and/or required key missing - tainting kernel
By default, kernel has the ability to load unsigned modules, but it taints the kernel as a security precaution. this tainting serves as a warning that the kernel may be running with unverified or unsafe code.
FYI,
we have the CONFIG_MODULE_SIG_KEY="certs/signing_key.pem" as the default setting.
the signing key is automatically generated in each kernel build, which means the signing key is different from each kernel building, thus, the kernel module compiled by user has different sig_key with the release one.
here’re couple of approaches to resovle this.
(1) you may configure CONFIG_MODULE_SIG as disabled to get rid of the message during modprobe/insmod.
or…
(2) you may try to specify your own sig_key using CONFIG_MODULE_SIG_KEY in kernel config, to rebuild the kernel and kernel modules, install the kernel image, dtbs and kernel modules to target.
after that, please use your own sig_key to sign the tegra-camera.ko built later.
please see-also developer guide for reference, Kernel Module Signing.
