['NULL' terminates entry]?
The Firmware Command Buffer contents contain the BUG commands which are executed upon
firmware startup.
BUG commands you place into the command buffer should be typed just as you enter the
commands from the command line.
The string 'NULL' on a new line terminates the command line entries.
All PPCBug commands, except for the following, may be used within the command buffer: DU,
ECHO, LO, TA, VE.
Note
Interactive editing of the startup command buffer is not supported. If changes are
needed to an existing set of startup commands, a new set of commands with changes
must be reentered.
Standard Commands
The individual debugger commands are listed in the following table. The commands are
described in detail in the PPCBug Firmware Package User’s Manual, listed in Appendix D,
Related Documentation.
Note
You can list all the available debugger commands by entering the Help (HE) command
alone. You can view the syntax for a particular command by entering HE and the
command mnemonic, as listed below.
