Preparing the Debugger

This example utilises the Monitor interface, which automatically
downloads a special Monitor kernel to the target hardware using the
Bootstrap mode. Depending on the Project|Options for Target
‘nM164’|Debug configuration, µVision2 will load the application
program and run the startup code.

•

 

Please select the check-boxes near: Use: Keil Monitor –166 Driver
and Load Aplication at Startup in the Project|Options for Target
‘nM164’|Debug dialog.

•

 

Click on the Settings button in the upper right corner of the
Options for Target ´nM164´ window.
