ANN: Freerunner Navigation Board v2 is finally available
Dear list, after lots of hard work I'm happy to announce that the Freerunner Navigation Board v2 is finally available! The team from handheld-linux.com [1] kindly offered to handle orders and shipping. The second version of the Navigation Board includes some features which go well beyond of what is needed for navigational purposes. The board comes in two assembly variants "standard" and "complete". See below for a feature description/comparison. The most recent documentation as well as possible use cases and bug descriptions can always be found on the wiki page [2]. Features supported by any board: * 3D magnetometer The magnetometer measures magnetic forces on three axes. With some math it can be used as a compass. Alternatively, use it to measure the magnetic fields generated by trains while accelerating (e.g. underground lines). * 3D gyroscope A gyroscope measures angular velocity. It can determine how fast you spin your Freerunner around its three axes. Usable to support the integrated accelerometers for inertial navigation (navigation without GPS) or to create a wireless game controller (like the wii). * Barometric pressure sensor The change in ambient air pressure is a good indicator for changing weather conditions. If the weather is relatively stable and the barometric pressure changes, it usually indicates that the height above sea level changed. If this value is known the absolute height can be calculated without using the GPS. * Four channel LED controller This LED controller can dim and make blink up to four LEDs (e.g. RGBA). It works autonomously, even if the main CPU is suspended. This may for instance be used to indicate unread messages. Large blinking intervals and duty cycles enable short flashes to save battery power. Alternatively one could connect a high brightness LED and use the Freerunner as a dimmable torch. * Seven channel touch controller The chip could actually control twelve channels, but due to space restrictions only seven are available on the FRNBv2. They can be used to add touch buttons to your Freerunner or act as proximity detector. E.g.: disable the screen lock if you pick up the phone. (*) Four channels can also drive LEDs, if you don't need them for something else. Additional features of the "complete" boards: * 12-Bit analog to digital converter This chip is very similar to the one used on the Freerunner Navigation Board v1 to digitize the output of the gyroscopes. The FRNBv2 does not use it for own purposes, it's completely under users' control. A possible use cases would be an ambient light sensor. Or use it to measure the current consumption of the FRNBv2 ;-) * Programmable oscillator Do you need to generate a rectangular signal with programmable frequency between 1kHz and 68MHz? Then this chip is made for you. What can you use it for? I thought about a 38kHz oscillator which can be enabled and disabled using a GPIO pin. This could be used as generic infrared remote control. If you really need these two last features, order a "complete" board or add the chips yourself to any "standard" board. They come in leaded packages and are hand solderable if you have some soldering experience. (*) This feature was not tested yet due to a missing kernel driver. I'm not sure if it will work as expected. (**) The programmable oscillator does not work due to a strange bug. See the wiki [2] for details. Have fun!

With Qi you can create a special file in /boot and it will skip this uSD partition. Then when you boot from NAND you can remove this file to boot from uSD next time.

Boot selection
Hi all, Is there a way to select where to boot from, nand or uSD? and i need a software choice, no the obvious boot select with the aux button, which requires physical access to the freerunner. So, given that i have no physical access to the freerunnner, how can i select where to boot from? Kind regards, Ed ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
