_ Extract Slackware file tree into MicroSD (on Slackware 14.2 x86)

Get SlackwareARM 14.2

• wget -c -np --passive-ftp -r ftp://ftp.arm.slackware.com/slackwarearm/slackwarearm-14.2/slackware/
• wget -c -np --passive-ftp -r ftp://ftp.arm.slackware.com/slackwarearm/slackwarearm-devtools/minirootfs/roots/slack-14.2-miniroot_01Jul16.tar.xz

Format MicroSD

• fdisk -l /dev/sdb

Disk /dev/block/mmcblk1: 31.9 GB, 31914983424 bytes
4 heads, 16 sectors/track, 973968 cylinders
Units = cylinders of 64 * 512 = 32768 bytes

Extract phase1

• mount /dev/sdb2 /mnt/tmp
• mkdir /mnt/tmp/slackware
• cd ~/ftp.arm.slackware.com/slackwarearm/slackwarearm-14.2/slackware/
• find . -name '*.txz' | xargs -I '{}' installpkg --root /mnt/tmp/slackware '{}'

• Put MicroSD into SD slot in phone
• start Terminal emulator
• su -
• cd /mnt/sdcard
• mkdir chroot

Create scripts to start Slackware

• mount /dev/block/mmcblk1p2 /mnt/sdcard/chroot

Start slackware

start Slackware with next commands from Terminal emulator.

• su -
• cd /mnt/sdcard
• sh slackware.sh
• sh .xinitrc

Change application to XSDL, then you will see xterm and twm running in it.

_ BUGS

Unfortunatery, binary built by gcc-4.7 or later requires __kernel_cmpxchg64 system call in kernel-3.1 or later.

So I have to say that SlackwareARM-14.2 is not suitable for Xperia SO-03D which is powerd by Android 4.0 with kernle-3.0.8.
