Precautions

Please take note of the following problem in using real-time OSes MR32R for the M32R family and MR30 for the M16C/60 and M16C/20 series of microcomputers.


Versions Concerned
Product NameVersions
MR32RV.1.00 Release 1 to V.2.00 Release 2
MR30V.1.00 Release 1 to V.3.00 Release 1


Description
Executing the configurator with the '-m' option may result in incorrect access to memory. (When using Windows 98 and 95, the execution may be aborted by page fault.)


Condition
This problem occurs only if the following condition is satisfied:
  • Inside the source program written in the C and assembly languages, the full path name (with the directory path) of include files is specified with a total of 32 or more characters.
    [Example]
    ---------------------------------------------------------------------- 
                                                                           
        #include  "mr32r\application\sample\SampleApplication.h"           
                                                                           
    ---------------------------------------------------------------------- 
    
Workaround
This problem will be circumvented by either of the following path name specifications:

  1. Specify the directory path and the file name with a total of less than 32 characters.
  2. Specify the file name with less than 32 characters and do the directory path using options of the compiler and assembler or setting environment variables. How to use the above options and set those variables differ between cross tools. For detailed information, refer to each cross tool manual.
