Hello,

We are trying to launch an example code “FreeRTOSPlusUDPandCLILPC1830GCC”, which is located in the latest official zip-file from FreeRtos: FreeRTOSv9.0.0FreeRTOS-PlusDemoFreeRTOSPlusUDPandCLILPC1830GCC

However, we can’t build the project because we get errors. Has anyone tested this example?

We are using LPCXpresso v8.2.0_647, but we also tried to build the code with another versions of LPCXpresso.

This is the list of errors, which we get:

_setPRIMASK is a cmsis library function, so it looks like there is a problem with including the cmsis core header file. Sometimes this header file is included explicitly using a

#include

and locating the header file in the application directory. Sometimes it is included implicitly by the tools and located in one of the tools library directories. I expect the way or method it is included has changed since the demo was created (it is quite old).

If you cannot work out how to get the cmsis header file into the code then simply add an implementation of _setPRIMASK into your application code. Googing _setPRIMASK will show you how it is implemented, just a few lines.

Thank you very much for your help. I worked it out and the demo works yet.
