Get Pdaxrom and flash it

(Make sure the CF card is formatted as FAT16, and format the SD card as ext2)

• get initrd and zImage
• Copy initrd.bin and zImage.5500 to the / of the CF card
• Follow flashing instructions available here: http://wiki.openzaurus.org/Collie/Install

Boot and configure the network

Power on ! The first boot will take a while (because of the sshd key generation). You should then get a prompt. Log in with root (no password)

# passwd (Change the password)
# setup the date with date if needed

# iwconfig eth0 essid <blabla>
# dhcpd (which is a dhcp client)

Log with ssh and play remotely

mv /usr/X11R6/ /mnt/card
ln -s /mnt/card/X11R6/ /usr/X11R6
rm -rf /opt /root /home
mkdir /mnt/card/opt /mnt/card/root /mnt/card/home
ln -s /mnt/card/opt /opt
ln -s /mnt/card/root /root
ln -s /mnt/card/home /home

edit /etc/ipkg.conf

src cacko-unstable http://www.tyrannozaurus.com/feed/contribs/telemetric/feed/collie.pdaxrom.feed
dest sd /mnt/card

ipkg update
ipkg -d sd install tk tcl automake autoconf make qt-mt

Pda

Installing pda

mkdir /mnt/card/src
cd /mnt/card/src
wget http://gige.xdv.org/pda/release/src/PDa-0.6-src.tgz
untar
cd PDa/src
make

Launching pda

The best is too launch startx from an ssh session (so it can be killed easily). 

Go in the "Other directory" and launch "aterm"
cd /mnt/card/PDa/src/bin

Launch PDa
./pd

Playing around with netsend/netreceive

GPS

HI-302CF compact flash GPS card

dmesg output
ttyS03 at port 0xc48503f8 (irq = 35) is a 16550A

stty -F /dev/ttyS3 ispeed 4800 && cat </dev/ttyS3
should show weird things.

ipkg install gpsd or compile one (the ipk was not working for me)
gpsd -N -n -D 3 /dev/ttysS3

cgpxlogger > trace.gpx

gpsdrive

gpsdrive -D -b 192.168.129.201

xgps

xgps 192.168.129.201:2947

Tricks

From an ssh session :
xwd -display :0.0 -root -out screenshot-pda-r1patch.xwd

edit /etc/ssh/sshd_config and add :
X11Forwarding yes

restart sshd

Problems/TODO

• right-click
• crackling sound
• launchers (PDa...)
• Automatic network config and X11 startup at boot
• Swap
