Our goal is to make a led blink on the AT91SAM9G20-EK board using
FreeRTOS high level functions.

Therefore we will be particularly carefull on compiler errors and

Advices for testing FreeRTOS port are available on the community
forum. Some advice to test the following behaviors : check the
tick frequency is correct with an oscilloscope, verify that
context switching is correct and run demo tasks.

packaged by the same manufacturer thant the port we git inspired
from. However, correct tick frequency and functionnal test are
required to be validated.

We will use the official port to AT91SAM9XE for reference and the
atmel demo software, however we will implement everything form
scratch.
* Notes
You shall note that AT91LIB was left untouched. The startup file has
been patched to load FreeRTOS callbacks on exception handlers in
src/boot_fstartup.S .
As well, to improve portability some scripts where re-written in
bash i.e. debug.pl .
The following makefile targets : jlink, flashing, connect are only
for convenience and call scripts for, respectively, start a j-link
communication, flashing the board and connecting to the debug
port. These scripts use third party software and should be adapted
according to your usage an set-up. They are included only for
convenience.
