This is a very common question too.

The diagram is a pictorial description of the differences followed by some explanations.

       I am using Cortex-M0 DesignStart Pro. When I use my program to simulation, I found the HADDR from 0, to 4, and the to ffff_fffd8, the  HRDATA is  0x2000_06f8 and 0x800_0159，the HADDR should not be ffff_ffd8，So I think it's unusual, but I don't know…

We are using Cortex-M0 DesignStart Pro to design MCU. When we use SWD to download grogram to flash in FPGA(Cortex_m0 mcu inside),  we cannot to connect keil with FPGA, and Keil shows:" Could not stop Cortex-M device!Please check the JTAG cable. "…
