Cosmic compiler for s12 producing RAM section in S19 file.

[sreedharannandu]

Hi All,

I am using the Cosmic compiler 4.8.9 for S12G128 freesclae micro.I have my own linker script and batch file to build the s19 record.

The problem i am having is RAM addresses are generated in the s19 file generated though i dont have any RAM data auto intialization enabled..

I tried using possible options in chex utility to suppress RAM address but i  just cant't stop it in s19 file.

How can i suppress this? Why is the linker populating RAM address section in s19 file?

I have attached the linker file and batch file for reference.Please clarify it.

Shown below is the s19 record.Highlighted in RED is the RAM address!!!!. But why?

Hello Nandu,

please check your map-file (Test.map). It says there is 40 bytes of global data declared in main.o which has initial values assigned.

If you comment this (or remove the assignment) in main.c:

volatile unsigned char data_global[20]={0x01};

volatile unsigned char data_static[20]={0x02};

then the RAM entries in the s-record file should be gone.

Hope that helps.
