hi i am trying to run a basic loop back program in cortex-m3 but error is coming

Error: JTAG-DP OVERRUN - check clock, memaccess, or reduce jtag speed
 

Some questions:

  • Have you tried at least reducing the jtag speed ?
  • What programmer are you using ?
  • Is it connected by ( a short ) flat cable ?
  • Have you checked voltages ? ( configured in programmer and on target board )
