Linux Fast Boot on i.MX6 Sabresd Board - NXP Community

I the above article. it is mentioned that

"Notice: Kernel configuration remove NETWORK support, it includes Unix Domain Socket, the udev mechanism need it, so this kernel configuration can't support rootfs udev dynamic /dev/ nodes and all /dev/ nodes must be created before boot up at rootfs"

I want to know how to create static /dev/ nodes before boot up without udev. We are usnig Yocto Zeus for i.MX8MM

Hi @shubham_sharmaa,

I hope you are doing well.

static device nodes can be created using the mknod command.

In yocto, one can add the mknod command to create a static node in the custom bitbake recipe's do_install() section.

Thanks & Regards,
