9S08jm60 to jm32 migration problem

S_B_D — Mon, 22 Dec 2008 20:43:38 GMT

Hi All,

Finished a project on the jm60 64 pin LQFP and now I would like to migrate to the smaller JM32 part (also 64 LQFP).

this is the linker error I get:

Link Error : L1119: Vector allocated at absolute address 0xFFFE overlaps with sections placed in segment .absSeg150

Link Error : Link failed

How can I fix this linker problem?

Thanks,

S.B.D

Hello

Just remove the command

VECTOR 0 _Startup

VECTOR ADDRESS 0xFFFE _Startup from your .prm file.

It looks like you did define the reset vector some other way in the source code,.

Thanks CrasyCat,

Will give it a go in the morning and post the results.

Hello CrasyCay,

As you said, removing the Vector 0 _startup from the .prm file did the trick.

Could you please explain a bit more (as my programming skills are higher level...) what I removed and why it's linking now..

Thanks for your help!

Hello

VECTOR 0 _Startup is initializing memory at 0xFFFE-0xFFFF with address of function _STartup.

Depending on how your application is build up, you may already initialize this vector table entry in your application (either with a constant table of function pointers or specifying a vector number together with the interrupt keyword.

If you look at the .map file generated by the linker you should be able to figure out what is allocated at 0xFFFE-0xFFFF.

I hope this helps.
