I want to port FreeRTOS to NXP make LPC1778 (Arm Cortex M3). Can you suggest the closest Demo Application to start with?

Hello Supriyo, I think the LPC1768 port would be good to start with – you can look under .…FreeRTOS_SVNfreertostrunkFreeRTOSDemo And you should see 3 Cortex_LPC1768 ports – should be enough to get started with and adapting the LPC1768 should be fairly straightforward. Good Luck, John W.
