Hi,

After removing external crystal oscillator and using internal RC oscillator of 12MHz PLLed to 72MHz is giving error in printf(). 

 printf() is not giving any output on putty, while TXDATA is working fine. 

also the following issue is showing up while stopping or pausing the debug.   

No source available for "__vfprintf() at 0x3114"

No source available for "printf() at 0x300a"

 

port and baud rates have been doublechecked. 

 

IDE   :   MCUXpressoIDE

Library : REDLIB

Clock   : Internal RC Clock PLLed to 72MHz

Processor   :   LPC1517
