CHAPTER 6 LINKER OPTIONS
6.2.39 User-specified-area Check Specification (-check_rora)
When the -check_rora option is previously specified, you can check whether the
memory map has been changed, by changing only the specified MB number.
The -check_rora option checks whether the specified ROM and RAM areas (-ro and -ra
options) correspond to the actual addresses of the internal ROM and internal RAM.
Use this option when single-chip mode is used.
■ User-specified-area Check Specification (-check_rora)
[Format]
-check_rora
[Parameter]
None
[Descriptions]
A check is made on whether the specified ROM and RAM areas (-ro and -ra options) exceed the
internal ROM and internal RAM.
The following warnings are output when the areas specified for the -ro and -ra options are not within the
internal ROM and internal RAM:
W1368L: The area specified for the -ro option is outside the internal-ROM area (area name)
W1369L: The area specified for the -ra option is outside the internal-RAM area (area name)
When the -check_rora option and the MB number are specified in using single-chip mode, a check is
made on whether the specified ROM and RAM areas correspond to the actual addresses of the internal
ROM and internal RAM of the product concerned. So, for instance, when a program is ported to a
different product, you can check whether the memory map has been changed, by changing only the
specified MB number.
Also, when the -check_locate option is specified together with the -check_rora option, you can check
whether the program is within the internal ROM and internal RAM.
[Example]
flnk911s -cpu MB91F155 -check_rora -ro ROM = 0x00080800/0x000fffff
-ra RAM1=0x00001000/0x00008fff, RAM2=0x00080000/0x000807ff ...
-> The areas specified for the -ro and -ra options are within the ranges of the internal ROM and internal
RAM; so no warning is output.
flnk911s -cpu MB91154 -check_rora -ro ROM = 0x00080800/0x000fffff
-ra RAM1=0x00001000/0x00008fff, RAM2=0x00080000/0x000807ff ...
W1368L: The area specified for the -ro option is outside the internal-ROM area (ROM)
W1369L: The area specified for the -ra option is outside the internal-RAM area (RAM1)
-> The underlined areas specified are not within the ranges of the internal ROM and internal RAM; so
the warnings are output.
