executed, allowing in-circuit reprogramming of the JM60 flash memory via USB. Refer to
Application
Note AN3561
on the Freescale website (http://www.freescale.com) for details on the USB Bootloader.
The USB Bootloader communicates with a GUI application running on a host PC. The GUI application
can be found on the
Freescale
website; search keyword “JM60 GUI.” Refer to section 2.5 and 3.3 of
AN3561 for details on installing and running the application.
Note:
The JM60 GUI Installer should be run before connecting the OSBDM in Bootloader
Mode to a host USB port. Otherwise, the JM60 USB device will not be recognized and
the proper drivers will not be loaded.
7 Bootloader Mode For MCF51MM256
Unlike MC9S08JM60, MCF51MM256 has an on-chip ROM based USB bootloader that allows the
MCF51MM256 for mass erase and programming via its USB interface. This on-chip bootloader does not
consume user flash space. To enable USB bootloader mode for MCF51MM256, on the TWR-MCF51MM
module, set SW3 DIP switch 2 and 3 to position 3, as indicated in Figure 7. NOTE: Under normal
development you will need to set SW3 DIP switch 2 and 3 to position 2.
