IMX8X yocto build

Hello,

I have successful build the linux image followed by the instruction below:

https://developer.toradex.com/software/linux/linux-software/build-apalis-imx8-yoctoopenembedded-bring-up-image?gclid=EAIaIQobChMIypn0zqbu4wIVkP7jBx2ULwrfEAAYASAAEgIOXvD_BwE

However, when I try to load a nimbelink modem, I had error message below:
modprobe: FATAL: Module option not found in directory /lib/modules/4.14.
78-toradex_imx_4.14.78_1.0.0_ga-bring_up+gb04d94e09628

Can someone answer how can I install /usb/serial/option.ko kernel module?

thanks,

For quick and dirty, I think you can include the following in your /build/conf/local.conf
CORE_IMAGE_EXTRA_INSTALL += “kernel-modules”
CORE_IMAGE_EXTRA_INSTALL += “linux-firmware”

Of course, you will want to circle back and add just the pieces you want. It should probably be added properly in your own layer as well.

It did not work, I am still having the same problem.

Found some info here. Might have to configure the right kernel options too. If you can’t find the option you are looking for, you can use “/” key in kernel menuconfig to search.
