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.

Creating my own binary :)
Apparently there are already devices out there that are very similar to this one, and hacks that support those devices.
First, I wanted to find out if some of the binaries on that site would work at all. So from the tweaks page, I copied the FTP binaries out there and set it up. It worked like a charm.
So I continued to explore through the page when I came across a link that was no longer valid on the site but it put me in the right location. This was on the linux page. But here is the critical link:
In there are the precompiled toolchains necessary for developing DIRECTLY ON THE DEVICE. The best way to do this:
Download the one called system-image-mipsel.tar.bz2 and extract the image-mipsel.ext2 file. I used WinRar. Put the .ext2 file on the root of the NTFS drive. Now telnet into the drive.
mount -o loop /usr/local/etc/hdd/volumes/HDD1/image-mipsel.ext2 root_fs
What that does is mount the image from your hard drive.
Presto. Now you can write C programs, compile them and run them. They didn't have any success doing this with the other multimedia players, but this worked beautifully on the Iomega drive. I wrote the basic "hello world" program in C, compiled it, made it executable, exited the chroot, and ran it. It displayed exactly what I wanted.
Cntrl-d to exit the chroot, by the way. gcc is the C compiler in that environment.
A whole new world to explore now. I believe many of the things found on that wiki site are going to be almost immediately usable on this drive. I have blogged all I'm going to blog on this device for the time being, as it will be much more beneficial to log this information into the wiki.
