Using the 187Bug Debugger

Note These logical port numbers (0 and 1) are shown in the pinouts of the MVME187 as ÒSERIAL PORT 1" and ÒSERIAL PORT 2", respectively. Physically, they are all part of connector P2.

Entering and Debugging Programs

There are various ways to enter a user program into system memory for execution:

❏Create the program with the assembler/disassembler

❏Download an S-record object file

❏Read the program from disk

Creating a Program with the Assembler/Disassembler

You can create a program using the Memory Modify (MM) command with the assembler/disassembler option.

1.Enter the program one source line at a time.

2.After each source line is entered, it is assembled and the object code is loaded to memory.

Refer to the Debugging Package for Motorola 88K RISC CPUs User's Manual for complete details of the 187Bug Assembler/Disassembler.

Downloading an S-Record Object File

Another way to enter a program is to download an object file from a host system.

The program must be in S-record format (described in the Debugging Package for Motorola 88K RISC CPUs User's Manual) and may have been assembled or compiled on the host system.
