Hardware Debug Features
2.3 Hardware Debug Features
The mini-debugger image is loaded into the CPU’s instruction cache at reset through
the CPU’s SROM interface. The mini-debugger provides commands to:
• Examine and deposit data in memory.
• Test memory.
• Examine and deposit internal CPU registers.
• Load an image into the motherboard’s memory and transfer execution to it.
The mini-debugger’s primary purpose is to debug hardware so that the memory
interface works, thus allowing a more complex debugger such as the Alpha
Microprocessors Debug Monitor to be loaded to debug other parts of the system or
software.
2.4 Setting Up the SROM Serial Port Connection
To use the mini-debugger, you must first establish a connection from your Alpha
microprocessor system or motherboard to the serial port on your host system. This
section describes how to connect the SROM serial port of an motherboard to the
following hardware:
• A terminal
• A PC running communication software
• A system running Windows NT
• An Alpha system running DIGITAL UNIX
2.4.1 Connecting the Motherboard to a Terminal
To connect a motherboard to a terminal, connect the SROM serial port of the
motherboard to the terminal communication line.
