OK, this is a long one, I tried to make all the instructions to compile a kernel for K4nt (I think
I use Debian (Jessie) as my host. At the end, I am able to add whatever modules I want. I highly recommend building your own modules!
HOST:
apt-get install debootstrap qemu-user-static binfmt-support
dd if=/dev/zero of=debian_image.ext3 bs=1M count=10000
mkfs.ext3 debian_image.ext3
tune2fs -i 0 -c 0 debian_image.ext3
mkdir -p /mnt/debian
mount -o loop -t ext3 debian_image.ext3 /mnt/debian
mkdir -p /mnt/debian/usr/bin
cp /usr/bin/qemu-arm-static /mnt/debian/usr/bin
for me, I use an iso of Debian Wheezy armel: debian-7.7.0-armel-DVD-1.iso
mkdir /mnt/iso
mount debian-7.7.0-armel-DVD-1.iso /mnt/iso
debootstrap --arch=armel --variant=buildd --no-check-gpg wheezy /mnt/debian file:///mnt/iso/debian
mkdir -p /mnt/debian/mnt/iso
mount --bind /mnt/iso /mnt/debian/mnt/iso
leafpad /mnt/debian/etc/apt/sources.list
deb [ trusted=yes ] file:/mnt/iso/debian wheezy main contrib
or continue using the web:
debootstrap --arch=armel wheezy /mnt/debian
http://ftp.us.debian.org/debian
mount -o bind /dev /mnt/debian/dev
mount -o bind /dev/pts /mnt/debian/dev/pts
mount -o bind /proc /mnt/debian/proc
mount -o bind /sys /mnt/debian/sys
chroot /mnt/debian /bin/bash
CHROOT:
apt-get update
apt-get install locales vim
dpkg-reconfigure locales *FYI I selected 138 (en_US.UTF-8)
vim /etc/apt/sources.list
deb
http://ftp.us.debian.org/debian wheezy main contrib non-free
deb-src
http://ftp.us.debian.org/debian wheezy main contrib non-free
apt-get update
FINALLY, here's the Kernel stuff!
HOST:
I downloaded and extracted the source, I think for Kindle4NT?? (Kindle_src_4.1.2_???)
then I copied the linux source to /mnt/debian/usr/src
CHroot:
apt-get install ncurses-dev
cd /usr/src
tar jxf linux-2.6.31.tar.bz2
cd linux-2.6.31
make imx50_tequila_defconfig
Here it gets interesting:
I downloaded source for Kindle Touch 5.1.0 and extracted to get a few files,
as per the Touch wiki.
from 5.1.0 for Touch:
copy these to the chroot usr/src/linux-2.6.31/include folder:
include/llog.h
include/linux/einkfb.h
include/boardid.h
** had to modify to add definition for finkle (just a hack to make it work,
I have NO IDEA what I'm doing
this was to make the display driver compile,
and we don't need that anyway.
#define BOARD_ID_FINKLE "004"
then, in the chroot you should be able to:
make menuconfig
*** make any changes, make into modules ***
make modules
from here, it's up to you - install the modules to your image and copy from there or
whatever you want. Good luck!
