Hello, I have recently ported from Keil compiler v5.16 to Keil compiler v6.13. On doing so, the porting was successful except for the fact that I can no more see deubg prints on RTT Viewer. On checking, I understood that "SEGGER_RTT_Syscalls_KEIL.c" expects __CC_ARM defination which compiler 6 does not use. I tested it with latest version of files but no luck. Can someone suggest a solution? Other details: Controller--> ARM Cortex M4 based.. IDE--> Keil uVision, system--> Windows.
