Raspberry Pi Quick Install Guide

Tue Oct 09, 2012 3:50 pm

I started a wiki page with easy instructions for installing Gentoo on a Raspberry Pi.
Using the standard kernel.img and modules makes it really easy and no need for cross compiling.
http://wiki.gentoo.org/wiki/Raspberry_P ... tall_Guide

Its a wiki, so any errors let me know or jump in and edit.

Nice what apps does it support? Not familiar with Gentoo wiki says it's a BSD base.

The link to the image is broken I believe it has YYYYMMDD is it supposed to be that way?

Can't wait to check it out and have a write up of it.

Gentoo uses a package management system call portage, it has more than 10000 "apps". Not all of them are tested or supported for ARM, but loads are.

YYYYMMDD is for year month day, to make sure you get the latest version of the image. I will update the docs to make it more clear.

I haven't done any overclocking yet but i am wondering if the settings in the gentoo wiki would void warranty?

http://elinux.org/RPi_config.txt says: "Warranty will be voided when you use force_turbo or current_limit_override or temp_limit>85 together with over_voltage>0". That seems to be the case in the config.txt example in the wiki.

I referenced this article -> http://www.raspberrypi.org/archives/2008
We’ve been doing a lot of work to understand the impact of voltage and temperature on lifetime, and are now able to offer a “turbo mode”, which dynamically enables overclock and overvolt under the control of a cpufreq driver, without affecting your warranty. We are happy that the combination of only applying turbo when busy, and limiting turbo when the BCM2835′s internal temperature reaches 85°C, means there will be no measurable reduction in the lifetime of your Raspberry Pi.
It is not really crystal clear, as the refer to turbo mode and not explicitly force_turbo. My interpretation is that running in "Turbo" will not effect your warranty, using force_turbo maybe does.

Hi,
I have already installed Gentoo linux on my Raspberry Pi 2 Model.
I followed the Raspberry Pi Quick Install Guide https://wiki.gentoo.org/wiki/Raspberry_ ... tall_Guide
I want to know whether is the kernel option:

Code: Select all

File systems  --->
     Pseudo filesystems  --->
          [*] Tmpfs virtual memory file system support (former shm fs)
activated in the pre-compiled binary kernel version: 4.1.16-v7+ ?

OK, I realised that that if I try to run the following command:

Code: Select all

mount -t tmpfs tmpfs /home/pali/tmpali/
and it success without error messages, than support for tmpfs in kernel is included.
Best, from Paul

Hi,

First, thanks for this guide, it's very useful.
I'm trying to create a gentoo systemd enabled image, so i'will try to contribute to https://wiki.gentoo.org/wiki/Raspberry_ ... ompilation as soon as i will have a working version. For now, one of difficulty is to get a working linux/.config file, so my first tests are about adding .config support to official tree as first custom and publish this kernel configuration.
I'm syncing kernel tree from :
https://github.com/raspberrypi/linux
using firmware from :
https://github.com/raspberrypi/firmware
and use portage overlay (with layman):
https://github.com/gentoo/arm
For now, trying to make work WIFI, I need to download nonfree resources and place them in /lib/firmware/brcm/ :
wget https://github.com/RPi-Distro/firmware- ... 0-sdio.bin -O /lib/firmware/brcm/brcmfmac43430-sdio.bin
wget https://github.com/RPi-Distro/firmware- ... 0-sdio.txt -O /lib/firmware/brcm/brcmfmac43430-sdio.txt
... ...
Well, i still have also some issues with libvpx compilation, but i hope to be able to launch a gnome-shell in few weeks. I will try to give some news in this thread.

Best regards.

I put my CFLAGS definition on :

Feel free to improve...

In the same way, i published my first tries (without genkernel) on :
https://wiki.gentoo.org/wiki/Raspberry_ ... ompilation
For now, i'm still looking for a kernel verified as working .config file...

I have also to try to include https://wiki.gentoo.org/wiki/Raspberry_Pi_VC4

Hi,

Now, i have a working custom kernel, so i'm going to start a new thread in this forum about this, (gentoo+systemd+gnome) so again thanks for sharing.

Return to “Gentoo”
