RFS building

Mon Dec 17, 2012 1:53 pm

Hello. I am interested if someone tried to build root file system for Rospberry, using BuildRoot, ie. u-boot, kernel and RFS. I would like to use NFS, because it is good during development phase. If so, it would be nice to share details with community.

Regards

When I get time, i'll be building up a very minimal OS from scratch. e.g. linux with busybox in a ramdisk. But hasn't happened yet - indeed haven't yet gout round to setting up an operational toolchain ...

From what I've seen, doesn't seem worth using uboot - as much as anything the binary blob that the GPU starts up from sets up everything needed to get the kernel up and running - so no point to running uboot.

Well, I was thinking about u-boot because it enables me (I think) to work from NFS, which I found to be usefull during RFS building. Or maybe it is also possible with already mentioned blob, but I don't know how.

Check out this buildroot-based RPi system I'm currently working on:

https://github.com/cellux/rpi-buildroot

Today morning I got to the point where the (buildroot-built) RPi kernel boots and mounts the (also buildroot-built) root fs over NFS.

I had to switch to the rpi-3.6.y kernel branch to make this happen, as rpi-3.2.27 produced a seemingly dwc_otg-related kernel oops (also discussed in http://www.raspberrypi.org/phpBB3/viewt ... 71&t=18545)

Return to “Linux Kernel”
