| Freescale's new generation MCUs HCS08 and its simplify version RS08 provide more than 200 types products. BDM technology inside them can help developer to promote their work. But many native users depend on foreign platforms to develop,so we design and implement HCS08/RS08 develop platform by us.The system include such as programmer and debug pod, hardware test system,PC host software etc.To support all kinds of MCUs of HCS08/RS08 and provide tools to debug C&ASM code are the most challengeable jobs as well as USB's device dirver.By measurement the frequence of target MCU so the host can communicate to target stably,and we bring forward the programmer&debugger pod to support all kind of MCUs of HCS08/RS08. The hardware test boards including all kinds of HCS08/RS08 MCUs can test and verify the quality of the pod. The suitable data struct help to step in/out the code and make the breakpoint to debug code through analyse the list file and the dbg file. The paper also describes in detail the coherent knowledge of the device driver, bring forward the USB device driver for the programmer and debugger pod. |
