How to kernel option to be activated?

#1

Hi.
Congratulate my first kernel build. Finally, I am trying it now. ^^;;
I’m trying to build Kernel following instructions here: RockpiS/dev/Debian - Radxa Wiki

I need to activate two options.

  • CONFIG_DEVPTS_MULTIPLE_INSTANCES
  • CONFIG_BRIDGE_VLAN_FILTERING
    I got to “make menuconfig”, the configuration window popped up and I stuck with it.
    I can’t find the two options in it.
    Or should I activate them in other place?

Please help kernel-build noob.

#2

Ok. Found out.

#vim .config

#3

The last part of the instructions.

Creating the ext4 image(linaro-rootfs.img):
./mk-image.sh

There’s error.
