This demo is targeted towards the EVBplus Dragon12-plus board, with 256 kB internal Flash EEPROM and 12 kB internal RAM.

To program the bootloader into the internal flash on the HCS12DG256 microcontroller, the P&E Micro USB BDM Multilink interface was used. However, this is not required if you have another means of programming the internal flash.

To compile the demo programs you can use the Freescale Codewarrior for HCS12(X) development environment.

Before the bootloader can be used, it needs to be built and programmed into the HCS12DG256's internal flash memory. The steps in this section only need to be done once.

When using Freescale Codewarrior, simply open the project from within Codewarrior and select Project→Make from the menu. The project file is located at: \Target\Demo\HCS12_Evbplus_Dragon12p_CodeWarrior\Boot\ide\

The bootloader program is now ready to be programmed into the internal flash memory of the HCS12DG256. Using your favorite programmer, flash the bootloader using one of the following files, depending on what file type your programmer supports:

• \Target\Demo\HCS12_Evbplus_Dragon12p_CodeWarrior\Boot\bin\openblt_evbplus_dragon12p.abs
• \Target\Demo\HCS12_Evbplus_Dragon12p_CodeWarrior\Boot\bin\openblt_evbplus_dragon12p.abs.s19
