3. 3 Follow the Project Wizard steps making sure you select the correct microcontroller derivative you are working with and the SofTec Microsystems target connection is used Starting your first Debugging Session The first time you enter a debugging session by selecting Project gt Debug from the CodeWarrior s main menu the MCU Configuration dialog box will open asking you to select the debugging hardware connected to the PC Make sure that the hardware code is set to PK HCS08GB60 MCU Configuration Hardware Model HW code PK HCSOBGB60 i Cancel Device Device code The MCU Configuration Dialog Box Page 23 4 Debugging Features Using Existing Projects with PK HCS08GB60 If your project has been targeted to an emulator simulator other than PK HCS08GB60 and you wish to use PK HCS08GB60 as the debugger for your project please do the following 1 If your project has been created with a version of CodeWarrior less than 3 0 make sure that the target command line option specifies the GDI target interface To do so a Open your existing project s settings dialog box b Inthe Target Settings Panels section click on the Build Extras item c If in the debugger s argument edit box the string target appears make sure that is set to target GDI 2 CodeWarrior is interfaced to the PK HCSO8GB60 engine through a so called GDI interface
4. The data transfer rate PC to target and target to PC is slow This results in high programming times For serious debugging we suggest you to switch to the SofTec Microsystems inDART HCS08 Series of debugging programming tools Page 6 PK HCS08GB60 User s Manual Background Debug Module BDM All MCUs in the HCS08 family contain a single wire background debug interface which supports in circuit programming of on chip non volatile memory and sophisticated non intrusive debug capabilities This system does not interfere with normal application resources It does not use any user memory or locations in the memory map and does not share any on chip peripherals The Background Debug Module also known as Background Debug Controller BDC uses a single wire communication interface via the BKGD line to allow non intrusive access to target system memory and registers PK HCS08GB6O0 features a USB to BDM circuitry which allows the host PC to communicate to the microcontroller through a standard USB cable Note in this microcontroller the BKGD line is shared with the PGO line same pin The user program therefore must not use the PGO line PK HCS08GB60 Board Layout The PK HCS08GB60 board has the following hardware features 1 A USB to BDM Interface section It contains the circuitry needed to electrically and logically translate BDM like commands sent by the host PC through the USB cable to the BDM interface
