Hello all,  
We are trying to create a new freertos port for Intel curie( c1000 x86 ISA compatible ) and iam trying to modify the Galileo demo by following the below link  
[http://www.freertos.org/porting-a-freertos-demo-to-different-hardware.html](http://www.freertos.org/porting-a-freertos-demo-to-different-hardware.html)

However there seems to be no partest.c file in IA32\_flat\_GCC\_Galileo\_Gen\_2 folder  
How may I proceed ?

Regards,  
Phani

Partest is a legacy name, which is just an abbreviation of parallel port test., and does nothing more than set, clear and toggle outputs - normally attached to LEDs. You can create your own partest.c file by implementing the functions specified by the prototypes in the header file of the same name.
