Remake SD image - notro/fbtft GitHub Wiki

Note: Superceded by FBTFT-image-build-process

This shows the steps used to make a SD image with FBTFT support. All done on the Raspberry Pi itself.

Make sure we have enough disk space, 2.5 GB is needed:

df -h
Filesystem      Size  Used Avail Use% Mounted on
rootfs          7.1G  4.2G  2.6G  63% /

Kernel build

This guide assumes the running kernel is compiled with FBTFT support as modules.

Install prerequisites

apt-get install zip kpartx

Download image

wget <mirror link>

Unzip image file

# Takes approx. 9 minutes
unzip 2013-02-09-wheezy-raspbian.zip

Mount partitions

mkdir /media/{bootfs,rootfs}
losetup /dev/loop0 2013-02-09-wheezy-raspbian.img
kpartx -a /dev/loop0
mount /dev/mapper/loop0p1 /media/bootfs
mount /dev/mapper/loop0p2 /media/rootfs

Copy kernel and modules

cp /boot/kernel.img /media/bootfs/
rm -R /media/rootfs/lib/modules/3.6.11+
cp -R /lib/modules/3.6.11+ /media/rootfs/lib/modules/

Enable SPI

Uncomment the SPI blacklisting

nano /media/rootfs/etc/modprobe.d/raspi-blacklist.conf

Unmount partitions

umount /media/bootfs
umount /media/rootfs
kpartx -d /dev/loop0
losetup -d /dev/loop0
