Getting
a Cross-compiler installed on your (Linux) desktop |
|
The easiest way is to download the binaries from
ftp://ftp.handhelds.org/pub/linux/arm/toolchain/ If you want to do it
yourself:

Things
to remember about the Familiar distr. and the iPAQ |
- The serial port (which is also used by the cradle) is called
/dev/ttySA0, as opposed to the standard /dev/ttyS0 since it is using a
different UART. To disable the terminal that respawns on that port: change
(delete or put a '#' in front of it) the appropriate line in /etc/inittab
and do init q to reinitialise without the port being occupied by the
serial terminal. Now you can use it for your own purposes.
- To make your own jffs2 files, download
ftp://ftp.uk.linux.org/pub/people/dwmw2/iPAQ/mkfs.jffs2 and execute:
"mkfs.jffs2 -r <rootdir> -o <jffs2-file> -e 0x40000 -p"
- Remember that the serial port does not supply enough power for most
(if not all) devices that take their power from the serial port.
- How to take a screenshot from your iPAQ:
http://www.handhelds.org/z/wiki/IpaqScreenshots: grab the screen
contents with: "cat /dev/fb0 > /tmp/screen.raw", get the file: "sz /tmp/screen.raw",
convert to ppm: "./raw2ppm screen.raw > screen.ppm" and
rotate and convert again: "convert screen.ppm -rotate 270 screen.png"
- sending files from iPaq to host via serial: "sz <file>"
- Finding out the status of the battery: "cat /proc/apm"
- Controlling the iPAQ led: "led <on/off: 0,1> <totaltime:
minutes> <ontime 100m/s> <offtime (100m/s)>"
- Rotating the screen: "/etc/init.d/x stop, /etc/init.d/x stop,
Xfbdev -screen 320x240 -dpi 100 &, blackbox&" is said to work best
