Motorola MVME177 manual Memory Search Starting Address

Set Environment to Bug/Operating System

Table D-1. ENV Command Parameters (Continued)

ENV Parameter and Options	Default	Meaning of Default
Memory Search Starting Address	00000000	Where the Bug begins to search for a
		work page (a 64KB block of memory) to
		use for vector table, stack, and
		variables. This must be a multiple of the
		debugger work page, modulo $10000
		(64KB). In a multi-MVME177
		environment, each MVME177 board
		could be set to start its work page at a
		unique address to allow multiple
		debuggers to operate simultaneously.
Memory Search Ending Address	02000000	Top limit of the Bug's search for a work
		page. If a contiguous block of memory,
		64KB in size, is not found in the range
		speciÞed by Memory Search Starting
		Address and Memory Search Ending
		Address parameters, then the bug will
		place its work page in the onboard
		static RAM on the MVME177. Default
		Memory Search Ending Address is the
		calculated size of local memory.
Memory Search Increment Size	00010000	This multi-CPU feature is used to offset
		the location of the Bug work page. This
		must be a multiple of the debugger
		work page, modulo $10000 (64KB).
		Typically, Memory Search Increment
		Size is the product of CPU number and
		size of the Bug work page. Example:
		Þrst CPU $0 (0 x $10000), second CPU
		$10000 (1 x $10000), etc.
Memory Search Delay Enable	N	There will be no delay before the Bug
[Y/N]		begins its search for a work page.
