- Q-1

If a variable is located in the external memory space, the following error occurs during linking.
*** ERROR F206 Segment segment name can't allocate to memory - ignored.
The following definition is made with the assembler. How should it be changed?PUBLIC _val0,_val1 DATASEG DSEG AT 0F100H _val0: DS 2 _val1: DS 2 END

To use an external memory space, a memory area must be defined
(internal ROM and internal RAM are defined by default).
In the above case, an error occurs during linking because the memory area of the external memory space is not defined.
Define an external memory area by a link directive, and specify so that the segment is located in that area.MEMORY ERAM :(0F100H,0100H) MERGE DATASEG := ERAM

The symbol generation specification option -S for resolving stack of the linker is used.
Can it be checked to where the stack is assigned?
- A-1
-
When the symbol generation specification option -S for resolving stack is used, symbol "_@STEND" that has the value of the lowest address of the stack, and symbol "_STBEG" that has the value of the highest address +1 are generated.
Specify the -KP option of the linker so that a public symbol list is output in the link list file.
The stack area is between the above symbols "_@STEND" and "_STBEG".
*** Public symbol list *** MODULE ATTR VALUE NAME NUM FE20H _@STBEG NUM FB7EH _@STEND
