Why ROM_LIB haven't linked or burned into .s19 file?

[pamis]

Hi

     I'm  working with bootloader, because of runtime library instead(eg. switch case, byte shift finally translate into _CASE_CHECKED_CODE, _BSHL...). I must separate APP and bootloader with rom library(normal library can't allocate address). Now, i create a bootloader rom library and link with app code, but there is no data in .s19 file..., help! Help! HELP!!!

snippet from project.map file:

Hi

To create .lib file, you need follow the steps below.(please also refer the attached mylib project)

1. Create one project with wizard.(I use NE64 as target chip)
2. change the file name main.c as the lib name (in sample is mylib.c)
3. define the lib functions in mylib.c
4. add header file mylib.h in the project, and declare the prototype of the lib functions in it.
5. add “#include mylib.h” in  mylib.c
6. delete the following files from the project: start12.c, datepage.c, *.prm, MC9S12NE64.h, MC9S12NE64.c, ansibi.lib.c
7. Press ALT+F7, in “Target Setting”, select “Libmaker for HC12” as Linker in the second droplist. In “Libmaker for HC12”, name your Library Filename.(the sample use mylib.lib), Click OK to close this window.
8. Compile again. In “bin” folder of the lib project, you could find the lib file named “mylib.lib”

• import “mylib.lib” and “mylib.h” in your current project

• add “#include "mylib.h"”in the main.c file

• then you can use the lib functions in your current project code.

please refer this to create your lib file. Hope this helps.

Have a great day,

Thank you for your reply.

    I used normal library instead of ROM library.

Thanks and regards
