RL_TCP on Cortex R4, RM48 - throwing Heap error : Heap was used, but no heap region was defined. What could be possible scenario?

Hi,

I have tried to port the RL_TCP from Keil on to my RM48 HDK. I am using the TCP_ARM_L.lib

I am getting an error as:

.\Objects\tcpstandalone.axf: Error: L6915E: Library reports error: Heap was used, but no heap region was defined

I have my scatter as:

FLASH 0x00000000 0x00300000

}

}

Could you please advice on this error.
