What is the advantage of JTAG support in ARM Processor which is not available in ordinary microprocessors.
 

Re: ARM

JTAG is a standard interface which is not true for dedicated debug interfaces found on most MCU's. Due to this standard interface its possible for other vendor's to design tools.
 

Re: ARM

Because of the JTAG support in ARM, we can have ICE boxes (In Circuit Emulators) or Trace boxes from other vendors and connect o ARM. The debugger on the host system can then use the drivers that comes with the ICE box to connect to the ARM. This helps a lot in debugging efforts.
