5 PPCBug

PPCBug includes commands for:

❏Display and modification of memory

❏Breakpoint and tracing capabilities

❏A powerful assembler and disassembler useful for patching programs

❏A self-test at power-up feature which verifies the integrity of the system PPCBug consists of three parts:

❏A command-driven, user-interactive software debugger, described in the PPCBug Firmware Package User’s Manual. It is hereafter referred to as “the debugger” or “PPCBug”.

❏A command-driven diagnostics package for the PrPMC800/800ET hardware, hereafter referred to as “the diagnostics.” The diagnostics package is described in the PPCBug Diagnostics Manual.

❏A user interface or debug/diagnostics monitor that accepts commands from the system console terminal.

When using PPCBug, you operate out of either the debugger directory or the diagnostic directory.

❏If you are in the debugger directory, the debugger prompt

PPC7-Bug>is displayed and all of the debugger commands are available.

❏If you are in the diagnostic directory, the diagnostic prompt

PPC7-Diag>is displayed and all of the diagnostic commands are available, as well as all of the debugger commands.

Because PPCBug is command-driven, it performs various operations in response to user commands entered at the keyboard. When you enter a command, PPCBug executes the command and the prompt reappears. However, if you enter a command that causes execution of user target code (e.g., GO), control may or may not return to PPCBug, depending on the outcome of the user program.

Memory Requirements

PPCBug requires a maximum of 768KB of read/write memory (DRAM). The debugger allocates this space from the top of memory. For example, a system containing 64MB ($04000000) of read/write memory places the PPCBug memory page at locations $03F40000 to $03FFFFFF.

PPCBug Implementation

PPCBug is written largely in the C programming language, providing benefits of portability and maintainability. Where necessary, assembly language has been used in the form of separately compiled program modules containing only assembler code. No mixed-language modules are used.
