I think NXP has benchmarks using different types QSPI, HyperRAM, HyperFlash for code and data. For code, I think it would be better to use HyperFlash over QSPI, with a 1Ghz processor, the more bandwidth the better. Yes, there is ITCM and internal RAM, but why waste the RAM when HyperFlash...

I was looking at running a RTOS on one of the processors to handle I2C, SPI and some general I/O but, I don't think the interrupt controller can assign HW interrupts across processors.

I was hoping vxWorks (Intel) would release the new RTOS for the Quark processor on the Edison along with the RTM (Reference Technical manual) documentation. I thought the goal was to run Linux on the Atom dual core and debug the quark core from the Atom via internal JTAG or debug registers on...

OK, if you have some source code I can help out.

Yes for fun; keeping up with HW/SW skills, but also using cheap receiver has only PWM outputs a PWM/PPM encoder is needed with Afro mini.

Here is a working version of baseflight ported to Teensy3.1 couple of bad photos

I ported baseflight firmware and had to a mod to baseflight-conifguration tool due to GPS not being installed. Which code base are you using

I would sugguest using protothreads Also provides a simple task management.

Good looking quad, is it possible to get a parts list? basic cost?

FYI, Found this board http://www.pololu.com/product/2594 the draw back is wiring the USB from the board to the teensy. This way no traces have to be cut.

To clearify; make a special USB cable with a diode inline of the +5V comining from the PC.

Is there some other way not to avoid cutting traces? The only other way I can think of is to mod the USB cable and cut VBUS..

Is there a supported CMSIS-CORE for the teensy supported by freescale?

I've start the same project using Android, basicly a smaller version of IOIO which only requires USB host mode. Also, have updated firmware so Android can now talk to the teensy 3.0. The main issues are: - Basic loader for Android (Since IOIO is really just an I/O level operation, once the...
