Slackware ARM on the Raspberry Pi
Since there are so many ARM devices coming on to the market, it is not possible to provide support for them all in the main tree.
The Raspberry Pi is supported outside of the official Slackware ARM tree by the Slackware community.
Slackware releases 13.37, 14.0 & 14.1
Since the release of Slackware ARM 14.0, there have been a number of community efforts to bring Slackware to the device:
|Site||Slackware versions||Using official Slackware packages||Installation methods||Notes|
|fatdog||14.0, 14.1||Yes||Slackware installer||An end-to-end HOW TO guiding you through the installation and setup process.|
|Stanley Garvey||14.0||Yes||Slackware installer & pre-made images||Pre-made installed OS images ready to copy to an SD card|
|Dave's Collective||13.37||Yes||Slackware installer||An excellent set of instructions in order to have Slackware ARM running on your Raspberry Pi.|
Although the community does its best to keep up with the hardware changes there may be times when the above notes and images are unusable. If this happens you may work around the problem by using a miniroot image and a functional boot partition from some other source (like borrowing them from rasbian). If the kernel is the only issue you can compile your own kernel from sources (see here for a guide on doing that http://elinux.org/RPi_Kernel_Compilation).
Here are the steps involved in setting up a minimal Slackware ARM system from a miniroot image:
Download the current stable raspbian image from http://www.raspberrypi.org/downloads Unzip it and mount the partitions therein via loopback and then put all that is needed in a tarball for later use:
root@darkstar:/tmp# fdisk -l 2013-09-10-wheezy-raspbian.img Disk 2013-09-10-wheezy-raspbian.img: 1939 MB, 1939865600 bytes 255 heads, 63 sectors/track, 235 cylinders, total 3788800 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: 0x000b03b7 Device Boot Start End Blocks Id System 2013-09-10-wheezy-raspbian.img1 8192 122879 57344 c W95 FAT32 (LBA) 2013-09-10-wheezy-raspbian.img2 122880 3788799 1832960 83 Linux root@darkstar:/tmp# losetup -o $((8192 * 512)) /dev/loop0 2013-09-10-wheezy-raspbian.img root@darkstar:/tmp# losetup -o $((122880 * 512)) /dev/loop1 2013-09-10-wheezy-raspbian.img root@darkstar:/tmp# mount -o ro /dev/loop1 /mnt/floppy/ root@darkstar:/tmp# mount -o ro /dev/loop0 /mnt/floppy/boot root@darkstar:/tmp# cd /mnt/floppy/ root@darkstar:/mnt/hd# tar vcpzf /tmp/raspbian_boot_stuff.tgz boot lib/modules/ lib/firmware opt/vc
Please note the sectors of the beginning of the partitions: 8192 and 122880. We need to multiply these by 512 to get the bite offset for the loop device setup. This is done by $((8192 * 512)) and $((122880 * 512)). You will need to change these if the image partitioning scheme changes.
Now partition and format an SD like this: (NB the “fdisk -l” is just to show how I partitioned my SD)
root@darkstar:~# fdisk -l -u /dev/sde Disk /dev/sde: 4093 MB, 4093640704 bytes 126 heads, 62 sectors/track, 1023 cylinders, total 7995392 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: 0xd0b5414a Device Boot Start End Blocks Id System /dev/sde1 2048 133119 65536 c W95 FAT32 (LBA) /dev/sde2 133120 7995391 3931136 83 Linux root@darkstar:~# mkdosfs -F 32 /dev/sde1 root@darkstar:~# mke2fs -t ext4 -b 4096 -i 16384 -m 0 -L root /dev/sde2 root@darkstar:~# mount -o noatime /dev/sde2 /mnt/hd/ root@darkstar:~# mkdir /mnt/hd/boot root@darkstar:~# mount -o noatime /dev/sde1 /mnt/hd/boot/
Now you can extract the Slackware ARM miniroot and then the raspbian_boot_stuff.tgz in /mnt/hd.
Edit the /mnt/hd/boot/cmdline.txt and add at the end “ro” and check that the root parameter matches the partitioning of the SD.
Edit the fstab to match your formatting (if that was like I suggested it will look like this:)
root@darkstar:/mnt/hd/etc# cat fstab proc /proc proc defaults 0 0 /dev/mmcblk0p1 /boot vfat errors=remount-ro 0 2 /dev/mmcblk0p2 / ext4 errors=remount-ro,noatime 0 1 root@darkstar:/mnt/hd/etc#
You can now umount the SD, insert it into the RasbberyPI and boot into your Slackware ARM miniroot to add whatever else you need.
I generally add whatever else I need by simply using wget to pull down slackpkg, installing manually the downloaded slackpkg, editing the mirrors file and then install the rest that's needed with slackpkg itself (internet connection is required for this).
You might want to edit or comment the serial console in inittab to suppress the “s0” respawning to fast message.
