Firmware and Components in Hava Titanium HD

Last night after I hooked up the first Hava I took a look at the software that came with it. One of the directories on my pc contained the latest firmware update for the Titanium in a file named “fw_jaldi-usb.270322.rup.img”. I took a look at it in a hex editor and it contains two “cramfs” disk images. I extracted and took a look at the first one. It’s the /bin, /config, /config.default, /dev, /etc, /home, /lib, /lost+found, /mnt, /proc, /root, /sbin, /sys, /tmp, /usr, and /var directories from an embedded linux. These directories contain executables and scripts but don’t seem to be a complete os. I’m guessing that the second cramfs image contains the rest of the software. I’ll have to see when I unpack the second image.

I took the second Hava Titanium apart a little while ago. The case comes apart easy. The rubber feed are little cylinders that pop out exposing the four screws that hold the case together. I like these much better than the more common stick on feet, you can put these back easily. Once you remove the four screws the case top snaps off easily and you can see the pcb inside.
