Raspberry Pi 2 Compatibility List

Gentoo Linux for Raspberry PI 2 Raw Disk Image Download

The Raspberry Pi 2 Model B is a quad-core arm 900 MHz 32bit core based single board computer for experimenting with programming languages and hardware control. It has got 1G DDR2 RAM, HDMI, 4 USB 2.0 ports, 100 Mbit Lan, MicroSD card slot, a 40 pin GPIO and power from miniusb. Completely compatible with rpi. Python is a good choice to use with the RPI. And (also) for GUIs PyQt library (in QT Designer) is recommended. The code must not be compiled and runs on almost any machines ...

targets: [install/download] [modules] [hw/sf lists] [display link / dual monitors / usb vga adapter / xrandr] [set usb snd default] [rpi projects] [openbox theme] [accelerated x driver]
this hardware is successfully running on a Rpi2:

Install notes ...

building your own linux (sys-boot/raspberrypi-firmware)

 root # cd /tmp/
 root # git clone --depth 1 git://
 root # cd firmware/boot
 root # cp -r * /mnt/gentoo/boot/
 root # cp -r ../modules /mnt/gentoo/lib/ < this takes about 1 day (compiling with all dependencies) ~550MB

after installing base system and desktop is about 3,4 G

Kernel Modules

this modules must be loaded when using hardware listed on top in:/etc/conf.d/modules :

 #load the modules in the right order (depends)
 #modprobe snd_bmc2835 manually - if does not load ># modprobe --show-depends snd_bcm2835
 #cifs and snd-bcm2835 does not load
 #basename -s ".ko" $(find /lib/modules/$(uname -r) -type f -name "*.ko")
after preparing the sd card and installing kernel and modules (like this)-

save building time: use my gentoo!

Raspbian packages are outdated, so here is my alternative:
a image of my clean (german) linux can be downloaded
here ~3,4 G 2017-01-22
checksum: 4075a1514561cb9e56590b4340aad540 (Kernel 4.4.44, including 1GB swap partition) : it can be expand with more software that is available in portage. The source files are still included if you want to re-emerge with new USEFLAGS (/etc/portage/make.conf). Remove unused disfiles with eclean-dist.
Make sure your card is larger than 16GB (min. use 16gb microsd uhs-1 class 10 (rpi2 can not write faster than 25mb/s) is about 7€ > this is optimal )
>load kernel modules I have payed attention that you can start with python immediately (it is integral in gentoo).
gunzip -c gentoo.img.gz | sudo dd of=/dev/sdX
 # X is your disk
 #this will erase all data!
 #note: you can check partition table of extracted image with #fdisk -l gentoo.img
 #mount boot partition eg (512 x startsector):#mount -o loop,ro,offset=1048576 gentoo.img /mnt/iso 
 # after this insert microsd, boot pi2, login (w. standard user and pwd like in raspbian / pi:raspberry)
 # and expand filesystem:
 sudo resize2fs /dev/mmcblk0p3

.. it comes with:

used hardware :lshw installed software :world desktop modifications :lxdemod
Sorry, but there is no flash plugin available for arm, yet ...
Have fun with this lightweight ram saving out-of-the-box solution on your RPI2!

set usb soundcard default (/etc/modprobe.d/alsa.conf)

 options snd-usb-audio index=0
 options snd-bcm2835 index=1
 # and also comment this lines  
 #options snd-pcsp index=-2
 #options snd-usb-audio index=-2
 #reboot !
 speaker-test -c 2 -l 3 -D sysdefault:CARD=0

Display link, dual monitors with usb vga adapter and xrandr

Look & Feel:

It should be enough to update system with:
emerge --sync
 emerge --ask -uDU --with-bdeps=y @world --keep-going

Feedback Wanted!! >here< or in forum on
to do: dual boot(usb), memtest
