An MSS file is case insensitive and any reference to a file name or instance name in the MSS file is also case sensitive. Comments can be specified anywhere in the file. A pound (#) character denotes the beginning of a comment, and all characters after it, right up to the end of the line, are ignored. All white spaces are also ignored and carriage returns act as sentence delimiters.
The keywords that are used in an MSS file are as follows:
- BEGIN
- The keyword begins a driver, processor, or file system definition block. BEGIN should be followed by the driver, processor, or filesys keywords.
- END
- This keyword signifies the end of a definition block.
- PARAMETER
- The MSS file has a simple name = value format for statements. The PARAMETER keyword is required before NAME and VALUE pairs. The format for assigning a value to a parameter is parameter name = value. If the parameter is within a BEGIN-END block, it is a local assignment; otherwise it is a global (system level) assignment.
Requirements:
The syntax of various files that the embedded development tools use is described by the Platform Specification Format (PSF). The current PSF version is 2.1.0. The MSS file should also contain version information in the form of parameter Version = 2.1.0, which represents the PSF version 2.1.0.
MSS Example:
An example MSS file follows:
parameter VERSION = 2.1.0
BEGIN OS
parameter PROC_INSTANCE = my_microblaze
parameter OS_NAME = standalone
parameter OS_VER = 1.0
parameter STDIN = my_uartlite_1
parameter STDOUT = my_uartlite_1
END
BEGIN PROCESSOR
parameter HW_INSTANCE = my_microblaze
parameter DRIVER_NAME = cpu
parameter DRIVER_VER = 1.0
parameter XMDSTUB_PERIPHERAL = my_jtag
END
BEGIN DRIVER
parameter HW_INSTANCE = my_intc
parameter DRIVER_NAME = intc
parameter DRIVER_VER = 1.0
END
BEGIN DRIVER
parameter HW_INSTANCE = my_uartlite_1
parameter DRIVER_VER = 1.0
parameter DRIVER_NAME = uartlite
END
BEGIN DRIVER
parameter HW_INSTANCE = my_uartlite_2
parameter DRIVER_VER = 1.0
parameter DRIVER_NAME = uartlite
END
BEGIN DRIVER
parameter HW_INSTANCE = my_timebase_wdt
parameter DRIVER_VER = 1.0
parameter DRIVER_NAME = timebase_wdt
END
BEGIN LIBRARY
parameter LIBRARY_NAME = XilMfs
parameter LIBRARY_VER = 1.0
parameter NUMBYTES = 100000
parameter BASE_ADDRESS = 0x80f00000
END
