error: #35: "SSP not configured in RTE_Device.h!"

As it's come from a #error directive, it is probably of the form:

#if some-condition
:
:
#else
#error "SSP not configured in RTE_Device.h!"
#endif

So looking at the condition should give you a clue as to what needs setting ...

i am a beginner in arm ... i found it hard to correct it...i checked in the RTE_Device.h but i think SSP is already configured in it i m including the code part of ssp configuration in RTE_DEvive.h bellow

can you help me with it

i found this difficulty when i was using my gcld to display
