In short: Intel Edison is a very small and powerful (dual-threaded Intel Atom CPU at 500 MHz and a 32-bit
Intel Quark microcontroller at 100 MHz) new embedded system running a full linux system.

It could be utilized in numerous ways with Jolla via wireless connections (wifi/bluetooth) or i2c. It's even compatible with Jolla's 3,3 V output and 1,8 V interrupts (GPIO), so integration will be very easy.

Do you have any new ideas for TOH's which could use Edison?

to start off, attach a big-*** SD card

512 GB Then you would have two Linux systems running in your pocket with a memory of a desktop computer

I would like to see this Edison TOH with just two functions:
* full USB host mode support
* SD card support

I would then buy some ginormous SD card and put plenty of HD music on it, and I would connect my iFi iDSD nano to USB port and stream music through it. This would be great deal to any audiophile

I did some investigation about interfacing Edison with Jolla. Currently it seems that there's no way to integrate Edison as a slave device straight though i2c with Jolla.

1) Linux couldn't be an i2c slave until recently (https://www.kernel.org/doc/Documenta...lave-interface and https://lwn.net/Articles/611332/). I have to check which kernel version Edison is currently running + does the i2c controller on it support slave mode (edit: it doesn't: http://git.yoctoproject.org/cgit.cgi...f9a8387ebd33a8).

2) Edison has a built-in microcontroller called Quark in addition to the 2-core 500 mHz processor. The MCU was not accessible before the latest update which was released this month. It's running a special “ViperOS” RTOS derived from the VxWorks platform. The API on it is currently pretty limited, but I tried to implement software emulated i2c slave on it with no success. The MCU has some timing and reliability problems (https://communities.intel.com/thread/67355). Time will tell if it can be used to do some actual low level stuff.

To wrap this up: currently Edison can be integrated with Jolla only via additional hardware (and wirelessly of course, but no fun in that ). By additional hardware I mean i.e. i2c -> uart bridge.
