The IOIO, a breakout board for Android phones that predates the Android Developer Kit hardware, is a now a little bit easier to upgrade. That’s because [Ytai’s] IOIO manager app just his the Android market. The PIC24F that sits proudly on top of the board has always been running a bootloader, but for security reasons it is programmed to only talk to apps that have been officially signed. Now that there’s an app that meets this qualification, you can upgrade the firmware from your phone without the need for an external programmer.
What about the bootloader itself? Surely that will need upgrades over time, right? Well, yes. [Ytai’s] announcement today also came with an option for upgrading the bootloader but with one caveat. You’ll need two IOIO boards to complete the upgrade. One connects to the phone and becomes a programmer, while the other lays back and waits for a refreshing code flash.
