PowerPC MPC85XX/QorIQ specific SYStem Commands
SYStem.BdmClock
Set BDM clock frequency
Selects the frequency for the debug interface. For multicore debugging, it is recommended to set the same
JTAG frequency for all cores.
SYStem.CONFIG.state
Display target configuration
Opens the
SYStem.CONFIG.state
window, where you can view and modify most of the target
configuration settings. The configuration settings tell the debugger how to communicate with the chip on
the target board and how to access the on-chip debug and trace facilities in order to accomplish the
