Entering and Debugging Programs
There are various ways to enter a user program into system memory for execution. One way is to create the program using the Memory Modify (MM) command with the assembler/disassembler option. You enter the program one source line at a time. After each source line is entered, it is assembled and the object code loads into memory. Refer to the Debugging Package for Motorola 68K CISC CPUs User's Manual for complete details of the 177Bug Assembler / Disassembler.
Another way to enter a program is to download an object file from a host system. The program must be in
Alternately, the program may have been previously created using the 177Bug MM command as outlined above and stored to the host using the Dump (DU) command. A communication link must exist between the host system and the MVME177 port 1. (Hardware configuration details are in the section on Installation and
Another way is by reading in the program from disk, using one of the following disk commands:
❏BO
❏BH
❏IOP
Once the object code has been loaded into memory, you can:
❏Set breakpoints
❏Run the code
❏Trace through the code
