HCS12 Recompiling Libraries for Lower Part of Flash

JonByar — Fri, 25 Jan 2008 14:45:19 GMT

I am using a HCS128E microprocessor with Codewarrior v4.6.

I want to use the lower page of flash (0x4000 - 0x7FFF) for my code. The following line is in the default PRM file:

                              /* in case you want to use ROM_4000 here as well, make sure
                                 that all files (incl. library files) are compiled with the
                                 option: -OnB=b */

How do you recomile the libraries to make them work in the lower section of flash?

Thanks.

Hello

I would proceed as follows:

- Start CodeWarrior

- Open your project

- Check which ansi library is linked to the project

- Select File -> Open

- Browse for {Install}\lib\hc12c\hc12_lib.mcp (where {Install} stands for your installation directory).

- Select the appropriate build target for the library file you are using

"C Mb IEEE32/32" if you are linking "ansib.lib" to your application, ...

You can check which is the lib file generated as follows:

- Open target settings dialog (Press ALT + F7)

- Switch to "Libmaker for HC12" panel.

- The library file generated is displayed in the Library file name edit box.

- Once you have found the appropriate target, open the target settings dialog (Press ALT + F)

- Switch to "Compiler for HCI" panel and add the option to the Command line.
