I want to boot my Raspberry Pi 2 with a custom configuration. Therefore I have a kernel image and an initramfs file. The /boot directory looks like this:


I would like to use the minimum of files in /boot. I copy:


from https://github.com/raspberrypi/firmware. After that I create the file


with the arguments for the kernel. Finally I create


with the following content:

initramfs my_initrd.img followkernel

My questions:

  • Is this enough to boot the Raspberry Pi 2 or do I need something else?
  • Can I remove fixup.dat?

I don't know about fixup.dat but — provided you derived your kernel configuration from the Pi2's — replace the kernel and initrd and Bob's your uncle. FYI I did that with an Orange Pi, not exactly a Raspberry Pi but it's close. My kernel was compiled on a Gentoo environment and fetched from Sunxi 3.4. It did work.

  • Ok, I'll give it a try, the second SD card has just arrived. – fhmgufs Dec 23 '15 at 12:56
