Hacking devices can/will void your warranty and can turn your expensive consumer electronics into worthless trash if you don't know what you're doing. This blog is for information purposes only, and if you try to hack into your own consumer electronics, you do so at your own risk. The device I'm currently hacking is the Canon SX10 IS camera.

RootApp and Wifi
I've also worked on trying to understand the wifi. When you disable the DvdPlayer from starting up, it doesn't mount the media partition or link the media drive to /tmp/hddmedia. It also doesn't configure the network/netmask and gateway for the wired or wireless connection.
At the beginning of the rcS file in the /usr/local/etc is the instructions for doing the network config, so I just adapted it for mine and added drive mounting and linking.
ifconfig eth0 192.168.0.2 netmask 255.255.0.0
route add default gw 192.168.0.1
mount /dev/ide/host0/bus0/target0/lun0/part4 /usr/local/etc/dvdplayer/hdd/volumes/HDD1
ln -s /usr/local/etc/dvdplayer/hdd/volumes/HDD1 /tmp/hddmedia
And of course I took out the RootApp DvdPlayer command so that it wouldn't activate the DvdPlayer. This has left two things for me to solve. #1) How to control the blue light. It continues to flash after booting, and the bootscreen stays up. Well, the HelloWorld can take care of the bootscreen, but figuring out what controls that power light has been more difficult. #2) Wifi does not get set up.
which installs the ehci-hcd and ohci-hcd modules using modprobe.
I think it also needs:
I found this info in the Main DvdPlayer as well:
/bin/echo nameserver 127.0.0.1 >> /etc/resolv.conf
ifconfig wlan0 up
wpa_supplicant -P/var/lock/wpa_supplicant.pid -D ipw -c /tmp/net/wpa.conf -i wlan0 -B
wpa_cli -p /tmp/net/wpa_supplicant status > /tmp/net/WPA.STATUS;touch /tmp/net/WPA.OK
The /tmp/net/wpa.conf file is added when DvdPlayer runs, but it looks something like this:
psk="your wifi passphrase"
I've extracted information and found a webpage about setting up which has helped.
But I'm actually stuck at ifconfig wlan0 up. wlan0 isn't there. The light doesn't come on in the wifi adapter so I think the port needs to activate power or recognize the device or something similar. NetworkSet.cpp (can be found in Conceptronic sources) gives some hints but I haven't understood it yet. Anyway, that's what I'm working on now.
