Hello, every one

I have a simple question about .prm file format

I simply understood .prm in codewarrior, which allocate memory map between source code and physical memory.

so, I want to know more detail about how to allocated memory using expression or grammar in .prm( i don't know what i will say)

could you tell me keyword for searching .prm expression or reference?

Thank a lot

Hi Gidong

Not sure if I understand you correctly. I guess you want to know the method of allocating code/data to a specific memory address in source code. if yes, the normally used pragma to specify the code and data in C source file:
#pragma CODE_SEG <code section>
#pragma CONST_SEG <const code section>
#pragma DATA_SEG <data section>

here <code section>, <const section> and <data section> are defined in prm file.

You can refer Compiler manual in your Codewarrior install directory. Search key word in this file to learn more.

Have a great day,
Jun Zhang
