Out of allocation space in segment RAM at address 0x3E65? MCS9XDP512.

[Pang]

Hi everyone

My project has a problem withe linker. After compilation, the linker reported an error message:

"Out of allocation space in segment RAM at address 0x3E65."

How should I do with this messesage? My compiler option  is

-CpDPAGE=0x34 -CpEPAGE=0x36 -CpGPAGE=0x10 -CpPPAGE=0x35 -CpRPAGE=0x16 -CPUHCS12X -D__FAR_DATA -Ml -OnB=b -PSegObj -WmsgSd1420 -WmsgSd12056

Is there something wrong?

Thanks a lot for your inputs.

Hello

Apparently the memory area RAM is not big enough to store all your global variables.

I would start with looking at the map file generated by the linker. This could show you which variables have not been allocated yet.

Solutions here are:

  - If you have big arrays check if you can define them smaller.

  - You may want to place some variables in banked memory. You have then to define them in a user specified section. Please refer to technical note TN248 for information on how to do that.

Technical notes can be downloaded from our HC12 web page.
