TM4C129ENCPDT: Memory map prevented 0x1FFFFF50

Selim Nazli

Part Number: TM4C129ENCPDT

When I run an ordinary "Hello World" program with the TM4C129ENCPDT processor using Code Composer Studio, I get the error Memory map prevented reading 0x1FFFFF50, and it also opens the fputc.c file. I can't get the printf() function to run at all. Could you explain in detail the solution and reason for this error, I am new to this processor.

Hi,

A printf will take up space on the heap. You need to allocate heap memory in the linker in order for the printf to work. Set the heap to 1024 or higher should do it.
