    Raspberry Pi 2: How to upgrade kernel?

    I installed kali-2.1.2-rpi2.img on an SD card to try out on my Raspberry Pi. It works OK, but I need to compile a driver for my wifi card. For that I need kernel headers. And the kernel headers for the kernel that came pre-installed, 4.1.19-v7, don't seem to be available.

    So I did what I usually do, install a new linux-image. I installed linux-image-4.9.0-kali3-armmp. (Version number is shown as 4.9.13-1kali3). I can see that that's what's in /boot. But when I reboot, it just comes back as 4.1.19-v7. Is there something else I need to do to upgrade the kernel?

    Perhaps I need to install a new kernel.img on the boot partition, but I can't find clear instructions on doing that. Other distributions I've used on the Raspberry Pi haven't needed anything except apt-get.

    Good question, I'd like know the answer too.

    The kernel has to be purpose build for the Raspberry Pi. A stock arm build won't do.
    Why don't you use my kernel?

    That's based on the latest Raspberry Pi source with some Kali tweaks.

    Happy hacking,
    Check out "Sticky Fingers Kali-Pi":

    Now with mana-toolkit and more goodies!

    So... random person saying "hey, why don't you download and install my custom kernel on your security audit build" kinda sounds like someone's testing me ;-) Probably fine, but bad hygiene all the same.

    Alternative question: where do I get the official kernel headers package that matches the kernel Kali actually distributes?
