Traditional Mass Production/Distribution
Mass production encourages the culture of celebrity.
Focus to predict what kinds of product will be popular.
We, as human, are each different, of different needs.

pcDuino boot modes Default to boot from SD
If there is no bootable image in SD, it will try to boot from NAND.
For Ubuntu OS, the system and data in NAND can be copied to SD seamlessly.

Creating Your Own SketchRun Your Sketch
To run it, once you have wired up a switch and led to the right pins, type:
ubuntu@ubuntu:~/c_enviroment/output/test$ ./button_led
To stop the program, <Ctrl>C
A Quick Re-Cap
Add #include <core.h> to the top of your sketch.
Create your sketch in the samples folder (if your familiar with linux, makefiles, and compiling code, you could set up your own)
Add the filename to the Makefile in the samples folder in the OBJS section without the .c
Run make
Run the executable from the output/test folder.
You can introduce command line arguments into your sketch to make it more transportable.
