The mini2440 is the perfect hardware platform for my project.
Most folks seem interested in my step-by-step installation instructions.
As a Java programmer I really didn't relish the idea of having to learn Qt or another GUI toolkit for this lone project. So, I decided to install Android OS and leverage my Java skills. I had already planned to learn Android programming, and this was the perfect project. This site is a collection of things that worked for me as I installed the Android OS on the mini2440 and then programmed the thing using the Android eclipse plugins.
This is also my first project with the ARM family of CPUs. I found the ARM9 to be responsive and easy to work with overall. Making the transition from Intel/Linux to ARM/Linux wasn't that difficult. After the boxes boot they are pretty much the same. However the boot process, and OS install process, took a while to figure out. I didn't find a concise explaination for the boot process. I had to piece together an understanding from bits and pieces scattered across the net. I put this site together to consolidate my notes, and to help others.
The hardware for my project was ordered from within the US in early March 2010 from Industrial ARMWorks. I purchased mine with the Chameleon 1 case designed by esawdust. Industrial ARMWorks carries the enclosure as well, so I didn't get hit with two sets of shipping charges. Dispite a small snag that delayed shipping, I wouldn't hesitate to order from them again.
I needed access to the back button, and eventually others.
The good: the mini2440 exposes the buttons as IO pins.
The bad: the connector isn't something I had on my workbench.
The ughy: I took a scrap PCB board, soldered a standard .1" header onto it, and then soldered wire wrap wire from the IO pins onto the traces to the header. It works, and I can plug / unplug the button from the rest of the kit.
All of the connectors are unique enough that I couldn't located them on digi-key, mouser or any of the usual soruces. Also two of the serial ports are exposed as TTL logic levels. I intend to design and etch a breakout board to expose the interesting IO in a a more user-friendly format.
If I'm 100% honest with myself, the header board is really just an excuse to design and etch another board.
This site is a work in progress. Please leave feedback if I can improve the site in any way.
