I.MX6 Slackware

Slackware offers a mini rootfs which is simple to install and use our kernel.

These instructions have been tested with Slackware 14.1, but later releases also may work with these same instructions. First, use gparted, or other partition managers to create a single ext4 partition. Follow these instructions to install slackware to this partition.

# Assuming your SD card is /dev/sdd.  Check your distribution to be sure.
wget ftp://ftp.arm.slackware.com/slackwarearm/slackwarearm-devtools/minirootfs/roots/slack-14.1-miniroot_04Nov13.tar.xz

sudo mkdir /mnt/sd/
sudo mount /dev/sdd1 /mnt/sd
wget ftp://ftp.arm.slackware.com/slackwarearm/slackwarearm-devtools/minirootfs/roots/slack-14.1-miniroot_04Nov13.tar.xz

sudo tar -xf slack-14.1-miniroot_04Nov13.tar.xz -C /mnt/sd/

# Update the inittab to start getty on the right port
sudo sed --in-place 's/ttyS0/ttymxc0/' /mnt/sd/etc/inittab
# Update securetty as well to allow root to login over this port
echo "ttymxc0" | sudo tee -a /mnt/sd/etc/securetty

## Next you have to modify the fstab for emmc or sd.
#For SD:
echo "/dev/mmcblk0p1 / ext4 errors=remount-ro 0 1" | sudo tee -a /mnt/sd/etc/fstab
#For eMMC:
echo "/dev/mmcblk1p1 / ext4 errors=remount-ro 0 1" | sudo tee -a /mnt/sd/etc/fstab
sudo umount /mnt/sd

Before you boot this new image you should also update your u-boot command line arguments to include ro for fsck. Stop booting at u-boot and run these commands:

env set cmdline_append console=ttymxc0,115200 init=/sbin/init ro
env save

Once at the boot prompt, the username is "root" and the password is "password".
