PQIII Debugger | 8

Quick Start
Starting up the Debugger is done as follows:
5. Select the CPU to load the CPU specific settings. SYStem.DETECT CPU can set the appropriate
CPU automatically.
6. Specify that on-chip breakpoints should be used by the debugger, e.g. for program in FLASH.
7. Reset processor and enter debug mode
The core is now stopped at the reset address.
8. After SYStem.Up, only the boot page is visible for the CPU. Initialize MMU TLBs to configure
which memory is visible to the CPU at which address. See MMU.Set for details.
9. This step prepares the target memory for program loading. To configure the CPU for the access
to all memories either run the initialization code on your target or configure the CPU by using the
Data.Set command. For complete example scripts, see ~~/demo/powerpc/hardware.
10. Load the program.
The option of the Data.LOAD command depends on the file format generated by the compiler. A detailed
description of the Data.LOAD command is given in the “General Commands Reference”.
