-As long you use recent raspbian image the [[howtos:​hardware:​arm:​raspberrypi|Raspberry Pi 1 manual ​install method]] also works for the Pi 2.+==== Manual ​install method ​without a Raspbian image ====
  
 +As long you use the most recent release of firmware [i.e. post-June 2019] and the latest Raspbian Buster image the [[howtos:​hardware:​arm:​raspberrypi|Raspberry Pi 1 manual install method]] also works for the Pi 2.
 +
 +This method is for installing Slackware ARM 14.2 on a Raspberry Pi 2 model B without a Raspbian image.
 +However, it should work for other Slackware ARM and Raspberry Pi versions.
 +
 +=== 1. Partition and format the SD Card ===
 +
 +<​code>​
 +$ sudo fdisk -l /​dev/​mmcblk0
 +
 +Disk /​dev/​mmcblk0:​ 31.9 GB, 31914983424 bytes
 +4 heads, 16 sectors/​track,​ 973968 cylinders, total 62333952 sectors
 +Units = sectors of 1 * 512 = 512 bytes
 +Sector size (logical/​physical):​ 512 bytes / 512 bytes
 +I/O size (minimum/​optimal):​ 512 bytes / 512 bytes
 +Disk identifier: 0x00000000
 +
 +        Device Boot      Start         ​End ​     Blocks ​  ​Id ​ System
 +/​dev/​mmcblk0p1 ​           2048       ​67583 ​      ​32768 ​   b  W95 FAT32
 +/​dev/​mmcblk0p2 ​          ​67584 ​   62333951 ​   31133184 ​  ​83 ​ Linux
 +$ sudo mkfs.vfat /​dev/​mmcblk0p1
 +$ sudo mkfs.ext4 /​dev/​mmcblk0p2
 +</​code>​
 +
 +Remarks:
 +  * I use a 32GB SD Card
 +  * I choose 32MB for the size of the first partition
 +  * I let the empty space left for the second partition
 +
 +=== 2. Put the Raspberry Pi firmware in the SD Card ===
 +
 +<​code>​
 +$ git clone https://​github.com/​raspberrypi/​firmware.git
 +$ sudo mount /​dev/​mmcblk0p1 ~/mnt
 +$ sudo cp -r firmware/​boot/​* ~/mnt
 +$ sudo umount ~/mnt
 +$ sudo mount /​dev/​mmcblk0p2 ~/mnt
 +$ sudo mkdir -p ~/​mnt/​lib/​modules
 +$ sudo cp -r firmware/​modules/​* ~/​mnt/​lib/​modules
 +$ sudo umount ~/mnt
 +</​code>​
 +
 +=== 3. Put the Slackware ARM mini root file system in the SD Card ===
 +
 +<​code>​
 +$ wget -c ftp://​ftp.arm.slackware.com/​slackwarearm/​slackwarearm-devtools/​minirootfs/​roots/​slack-14.2-miniroot_01Jul16.tar.xz
 +$ sudo mount /​dev/​mmcblk0p2 ~/mnt
 +$ sudo tar -C ~/mnt -xf slack-14.2-miniroot_01Jul16.tar.xz
 +$ echo "/​dev/​mmcblk0p1 /boot vfat defaults 0 0" | sudo tee ~/​mnt/​etc/​fstab
 +$ echo "/​dev/​mmcblk0p2 /     ext4 defaults 0 0" | sudo tee -a ~/​mnt/​etc/​fstab
 +$ echo "​proc ​          /proc proc defaults 0 0" | sudo tee -a ~/​mnt/​etc/​fstab
 +$ PASSWD=$(openssl passwd -1 -salt cetkq/​enZx6/​c2 password)
 +$ sudo sed -i "​s|\(root:​\).*\(:​16983:​0:::::​\)|\1${PASSWD}\2|"​ ~/​mnt/​etc/​shadow
 +$ sudo sed -i '​s|USE_DHCP\[1\]=""​|USE_DHCP\[1\]="​yes"​|'​ ~/​mnt/​etc/​rc.d/​rc.inet1.conf
 +$ echo "​PermitRootLogin yes" | sudo tee -a ~/​mnt/​etc/​ssh/​sshd_config
 +$ sudo umount ~/mnt
 +</​code>​
 +
 +Remarks:
 +  * I set "​password"​ as password for the "​root"​ user
 +  * I set DHCP on the "​eth1"​ network interface
 +  * I allow the "​root"​ user to connect through SSH
 +
 +=== 4. Insert the SD Card in the Raspberry Pi ===
 +
 +Your SD Card is ready so you can insert it in the Raspberry Pi and boot.
 +
 +You can connect remotely to your Raspberry Pi as "​root"​ through SSH.
 +<​code>​
 +$ ssh root@raspberrypi
 +</​code>​
 +
 +As soon as you are logged, you might want to install additional Slackware ARM packages:
 +<​code>​
 +$ wget --mirror ftp://​ftp.arm.slackware.com/​slackwarearm/​slackwarearm-14.2
 +$ upgradepkg --install-new ftp.arm.slackware.com/​slackwarearm/​slackwarearm-14.2/​slackware/​*/​*.txz
 +$ removepkg ftp.arm.slackware.com/​slackwarearm/​slackwarearm-14.2/​slackware/​*/​kernel_*.txz
 +</​code>​
 +
 +Remarks:
 +  * I consider that the Raspberry Pi hostname is "​raspberrypi"​
 +  * I recommend to add a normal user and use this user instead of "​root"​
 +  * I recommend to change the "​root"​ user password
 +  * I recommend to disallow the "​root"​ user to connect through SSH
 +  * I recommend to [[https://​www.raspberrypi.org/​documentation/​linux/​kernel/​building.md|build your own Linux kernel]] packages because the kernel you are running does not match with the installed Slackware ARM packages
 +
 +=== 5. Tips and tricks ===
 +
 +== 5.1. Processor ==
 +
 +The Raspberry Pi processor can reach 1.2GHz.
 +However, by default, it is stuck to 600MHz even if it is used at 100%.
 +You can check the current frequency of the processor by typing:
 +<​code>​$ cpufreq-info</​code>​
 +
 +In order to reach 1.2GHz when the processor is used at 100% (i.e., use the frequency scaling), you need to change the default governors.
 +Add the following line to the end of the ''/​etc/​rc.d/​rc.local''​ file:
 +<​code>​echo ondemand | sudo tee /​sys/​devices/​system/​cpu/​cpu*/​cpufreq/​scaling_governor</​code>​
 +Now, the processor is correctly set.
 +
 +== 5.2. Time ==
 +
 +Unfortunately,​ the Raspberry Pi does not provide a Real-Time Clock (RTC).
 +That is why there is no battery included with the board.
 +It means that each time you shutdown the Raspberry Pi, the time is reset!
 +However, if you have internet access, you can update the time during the Slackware ARM boot.
 +Add the following line to the end of the ''/​etc/​rc.d/​rc.local''​ file:
 +<​code>​ntpdate pool.ntp.org</​code>​
 +Now, the time is correctly set.
 +
 +== 5.3. Video ==
 +
 +Unfortunately,​ the Raspberry Pi is not compatible with OpenGL (it is compatible OpenGL ES that is a subset of OpenGL).
 +It means that, by default, each application requiring OpenGL will be slow.
 +However, you can reach 60 FPS with OpenGL applications on the Raspberry Pi by using the correct driver.
 +
 +Firstly, you need to build Mesa (>= 17.0.4) with the VC4 DRI driver:
 +<​code>​
 +$ CFLAGS="​-O2 -march=armv8-a -mtune=cortex-a53 -mfloat-abi=softfp -mfpu=neon-vfpv4"​ \
 + CXXFLAGS="​-O2 -march=armv8-a -mtune=cortex-a53 -mfloat-abi=softfp -mfpu=neon-vfpv4"​ \
 + ./​configure \
 + --prefix=/​usr \
 + --sysconfdir=/​etc \
 + --with-dri-driverdir=/​usr/​lib/​xorg/​modules/​dri \
 + --with-egl-platforms=x11,​drm \
 + --with-gallium-drivers=vc4
 +$ make -j4
 +$ make install DESTDIR=/​where/​you/​want/​to/​install
 +</​code>​
 +Then build your own Slackware ARM Mesa package and install it.
 +
 +Secondly, add the following line to the end of the ''/​boot/​config.txt''​ file:
 +<​code>​dtoverlay=vc4-fkms-v3d</​code>​
 +Then reboot the Raspberry Pi.
 +
 +You can check that you are able to get 60 FPS with OpenGL applications on the Raspberry Pi by typing the following command in an X terminal:
 +<​code>​$ glxgears</​code>​
 +
 +Now, the video is correctly set.
