...If you are talking about the mbed board: 
ARM mbed LPC1768 Board and using the online mbed compiler, adding FreeRTOS is fairly easy. 
Under your project in the compiler, go to import and search "freertos". 
Import this library:

Make sure to include "FreeRTOS.h" in your project!

• Rohit Grover / This repository is a library FreeRTOS

• Tested example:

<cpp> // N.C. Freertos mbed minimal example based on below: // https://developer.mbed.org/users/rgrover1/code/FreeRTOS/ // http://www.radekdostal.com/content/freertos-610-minimal-example // 20/04/2017 update: Compiled for and NUCLEO-F104RB, without errors // Complile without errors: LPC1768,NUCLEO-F104RB,F401RE,L152RE // Compilation Errors for: EA LPC11U35, TG-LPC11U35-501 nRF51822, FRDM-K25Z, // nRF52-DK,BBC micro:bit,LPC1114FN28, NUCLEO-F030R8 // NUCLEO-F746ZG, LPC800-MAX

1. include "mbed.h"
2. include "FreeRTOS.h"
3. include "task.h"

   for (;;) {
