Tips for rev4 classic

Using muxer

To handle both GSM calls and GPRS data concurrently with one GSM modem, you need to set up a software multiplexer (gsm0710muxd). Wiki page GSMmuxer seems to be outdated for rev4.

  • change MUX=no to MUX=yes in /usr/bin/p and /usr/bin/x
  • change delay from 5 to 10 in /usr/bin/x (lines 65 & 69)
  • in /etc/ppp/peers/gprs :
    • line 36 : comment the /dev/ttySAC0 option
    • line 42 : uncomment the updetach option
    • line 43 : comment the nodetach option

Adding GPS, Bluetooth and Wifi icons on the top-left panel

To help seeing what is on, you can edit the file /usr/bin/x for adding the GPS and Wifi icon on the applet

nano /usr/bin/x

Find the line with “openmoko-panel-gsm” and add "openmoko-panel-bt, openmoko-panel-gps, openmoko-panel-wifi"

Wifi

There is bug in rev4, wifi device is eth0 instead of eth1, so scripts are not working properly.

Solution (http://trac.hackable1.org/trac/ticket/88) in udev rule /etc/udev/rules.d/70-persistent-net.rules should be only:

#shamelessly ripped from http://trac.hackable1.org/trac/ticket/50
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="sdio_wlan", KERNEL=="eth*", NAME="eth1"

Generic tips

Default boot on SD card

See this page.

Connectivity

GPRS

To set up your GPRS connexion, you first need to find the config file corresponding to your network. You have to search in the following directory

cd /etc/ppp/peers/prov
ls

Once found (for me, France-Bouygues ), just copy-paste it one folder up:

cp /etc/ppp/peers/prov/France-Bouygues /etc/ppp/peers/France-Bouygues

Then you need to modify the file /usr/bin/p and modify the variable PROVIDER= (at the beginning) with the name of the file you have just pasted

nano /usr/bin/p

To connect, just do

cd /usr/bin
./p

To disconnect :

killall pppd

Personnal folder

In hackable, the personnal folder is not /home/root/ like in the other distributions, but /root/ To help organizing your data, you can create the following folders

cd root/
mkdir Documents
mkdir Maps
mkdir MP3
mkdir Photos
mkdir Videos

If you want to copy some files from your desktop to your freerunner, you can use for example (from the freerunner xterm terminal). I suppose your login is mylogin on your desktop computer. You must have installed sshd (secure shell daemon) on your desktop.

scp -r mylogin@192.168.0.200:/home/mylogin/Photos/ /root/Photos

Change default ringtone

The ringtone is defined in the file

/etc/pulse/default.pa

Edit this file with vim (or nano or your favourite editor)

vim /etc/pulse/default.pa

Find the line that says "load-sample ringtone /usr/share/openmoko/sounds/ringtone_classy.wav".

Edit it to set the path to the new ringtone file. The folder /usr/share/openmoko/sounds already has many ringtones there.

The volumes for various sound states are defined in

/usr/share/openmoko/scenarios/*.state

Tips for older revisions

Font size

In order to see all the content of the windows of all the softwares I am using, I have reduced the system font size. For me , the best font size is 4. You have to edit /root/.gtkrc-2.0.mine

Setting-up swap space

For information on setting-up swap space, please go here

Installing for qi

  • qi first looks on ($first ext2/3 SD partition)/boot/uImage-GTA02.bin for the kernel
  • qi knows symlinks
  • you can pass arguments to the kernels via the ($first ext2/3 SD partition)/boot/append-GTA02 file

using ext2

  • You will have an easy time, all you need to do is extract the root tarball onto your ext2 partition
    mount /dev/mmcblk0p1 /mnt/mokoroot
    tar xzf h1-ext2_partition-rev3.tar.gz -C /mnt/mokoroot
    
  • then untar the fat partition image into /boot on this partition, link uImage.bin to uImage-GTA02.bin
    tar xzf h1-fat_partition-rev3.tar.gz -C /mnt/mokoroot/boot
    cd /mnt/mokoroot/boot
    ln -s uImage.bin uImage-GTA02.bin
    echo "root=/dev/mmcblk0p1 loglevel=8 rootfstype=ext2  rootdelay=5" > append-GTA02
    

Have fun, cheers!
