Revision as of 03:04, 25 March 2008
This page is to explain how to run debian armel port on neo1973. This instructions are likely to work on freerunner, too.
Contents |
1. (optional) install known good kernel
this kernel was build by Marcel_M and has some important patches in it such as removed sd debug symbols and build-in ext3 support.
wget http://rabenfrost.net/celtune/uImage-2.6.24+svnr4194-r4165-r3-neo1973.bin ./dfu-util -d 0x1457:0x5119 -a kernel -R -D ./uImage-2.6.24+svnr4194-r4165-r3-neo1973.bin
As there is no way to boot from sdhc with uboot directly I always copy my kernel to flash and let it boot my rootfs from sd but feel free to do it your way.
2. configure booting from sd/sdhc
Do as proposed here: Booting_from_SD
3.1. (option #1) debootstrap your own armel rootfs
debootstrap your rootfs on debian or ubuntu
debootstrap --verbose --arch armel --foreign sid ./armel-chroot http://ftp.de.debian.org/debian/
3.2. (option #2) download ready to use armel rootfs
wget http://rabenfrost.net/openmoko/armel-chroot-first-stage.tar.gz
4 prepare sd card
ssh to your neo and format your sd card appropriately. I'm using an 8GB shcd card here.
umount /media/card mkfs.ext3 /dev/mmcblk0p1 mount /dev/mmcblk0p1 /media/card
copy the armel chroot to your device by tar'ing it to circumvent symbolic link cycles (https://bugzilla.mindrot.org/show_bug.cgi?id=1059 <= WONTFIX)
tar -C ./armel-chroot/ -c . | ssh root@192.168.0.202 tar -C /media/card -xv
or if you downloaded the archive
cat armel-chroot-first-stage.tar.gz | ssh root@192.168.0.202 tar -C /media/card -xzv
5. complete debootstrap process
ssh to your device and execute the following commands (just copypaste everything below)
echo "nameserver 192.168.0.200" > /media/card/etc/resolv.conf echo "fic-gta01" > /media/card/etc/hostname echo "127.0.0.1 localhost.localdomain localhost fic-gta01" > /media/card/etc/hosts echo -e "auto lo\n\ iface lo inet loopback\n\ auto usb0\n\ iface usb0 inet static\n\ address 192.168.0.202\n\ netmask 255.255.255.0\n\ network 192.168.0.0\n\ gateway 192.168.0.200\n\ up echo nameserver 192.168.0.200 >/etc/resolv.conf" > /media/card/etc/network/interfaces echo -e "rootfs / ext3 defaults,errors=remount-ro,noatime 0 1\n\ proc /proc proc defaults 0 0\n\ tmpfs /etc/network/run tmpfs defaults,noatime 0 0\n\ tmpfs /tmp tmpfs defaults,noatime 0 0\n\ tmpfs /var/lock tmpfs defaults,noatime 0 0\n\ tmpfs /var/log tmpfs defaults,noatime 0 0\n\ tmpfs /var/run tmpfs defaults,noatime 0 0\n\ tmpfs /var/tmp tmpfs defaults,noatime 0 0" > /media/card/etc/fstab
now chroot into your armel rootfs and finish the install
chroot /media/card /debootstrap/debootstrap --second-stage echo "deb http://ftp.de.debian.org/debian sid main" > /etc/apt/sources.list apt-get update apt-get install openssh-server apt-get install locales dpkg-reconfigure locales apt-get install udev passwd
You may also copy some kernel modules over doing this (still on the neo)
wget http://rabenfrost.net/celtune/modules-2.6.24+svnr4194-r4165-r3-neo1973.tgz tar -C /media/card -xzvf modules-2.6.24+svnr4194-r4165-r3-neo1973.tgz chroot /media/card depmod -a
6. get x running
now reboot and start your debian. you can login with ssh and start configuring xorg:
apt-get install xorg
configure /etc/X11/xorg.conf so that it looks like this:
Section "InputDevice" Identifier "Configured Mouse" Driver "mouse" Option "Device" "/dev/input/mice" EndSection Section "Device" Identifier "Configured Video Device" Driver "fbdev" EndSection Section "Monitor" Identifier "Configured Monitor" EndSection Section "Screen" Identifier "Default Screen" Monitor "Configured Monitor" EndSection Section "ServerLayout" Identifier "Default Layout" Screen "Default Screen" InputDevice "Configured Mouse" EndSection
start x in the first vt:
startx -- vt1
7. get touchscreen working
install the tslib driver:
apt-get install xserver-xorg-input-tslib
create this link as the device is hardcoded for now:
ln -s /dev/input/event1 /dev/event0
and edit the InputDevice section in your xorg.conf
Section "InputDevice" Identifier "Configured Mouse" Driver "tslib" Option "CorePointer" Option "Device" "/dev/input/mice" Option "Protocol" "Auto" EndSection
calibrate your touchscreen
echo -67 36365 -2733100 -48253 -310 45219816 65536 > /etc/pointercal
start x and enjoy!!
startx -- vt1
