please help me out to solve this linker error?.....
 

The eeprom emulation code can take up a lot of memory, depending on how many pages you have defined.
Try to compile without the Emulation to see if that is the problem.
 
hi btbass,
i removed emulation file from project and compiled no changes same linking errors are giving
 

Are you using any of the dsp stuff that uses X and Y data spaces?

You could try changing the memory model in the compiler options to large.

can you tell why this linker errors are coming ? how i can fix this errors....


thank you
 

It seems to be having problems with 'asm_code'.
Try compiling without that file so you can isolate the problem.
 
hi, btsass
as you said i removed the asm code from my project and compiled..one linker error is removed but still one is remaining

thank you ..
 

data_init comes from the start up file.
It seems to suggest you have run out of memory?
 
I don't know.
The only thing I can suggest is that you remove one file at a time from the project to see if you can isolate what code is causing the problem.
