Funtoo on RPi2

The steps of installing Funtoo on RPi2, as a checklist for myself

1. setup the filesystem

   mkfs.vfat -F 16 /dev/sdf1
   mkswap /dev/sdf2
   mkfs.ext4 /dev/sdf3
   mount /dev/sdb3 /mnt/funtoo
   

2. download the stage3 tarballs

   cd /tmp
   wget http://ftp.osuosl.org/pub/funtoo/funtoo-current/arm-32bit/armv7a_neonvfpv4_hardfp/stage3-latest.tar.xz
   

3. extract the stage3 file

   tar xfp stage3-latest.tar.xz -C /mnt/funtoo
   

4. prepare the /boot and /lib/modules

   wget http://ftp.osuosl.org/pub/funtoo/funtoo-current/snapshots/portage-latest.tar.xz
   tar xjf portage-latest.tar.xz -C /mnt/gentoo/usr
   

5. setup /etc/localtime

   cd /mnt/funtoo/etc/init.d
   ln -s netif.tmpl netif.eth0
   

6. create config file
   • the netif file ln -s /etc/init.d/netif.eth0 /mnt/funtoo/etc/runlevels/default/netif.eth0
   • create /mnt/funtoo/etc/portage/make.conf
   • modify the /mnt/funtoo/etc/conf.d/hostname

7. setup ssh keys copy pubkey to the rpi2

8. boot funtoo boot the rpi2 and login the system date MMDDHHMMCCYY

9. after boot

   cd /usr/portage
   git checkout funtoo.org
   emerege --sync
   

10. choose the profile

    epro list
    

11. emerge the world

    emerge -avuDN @world
    

官方内核自带8192cu驱动，需要手动去掉 edit the drivers/net/wireless/Kconfig and drivers/net/wireless/Makefile

PS:内核从4.0开始已经支持8192cu比较好了，rpi官方已使用内核的驱动

make bcm2709_defconfig

cp arch/arm/boot/zImage /boot/kernel-$v-funtoo
