[fpc-devel] Arm embedded

[Carsten Bager]

Hi
I am trying  to move from FPC 205 to 251 my target is arm7 embedded
I have used the 205 compiler for several years, and it is working fine, but I would like to use 
some of the new facilitates 
When I compile my test program  (Begin End. ) the new linker misplace the segments.
Something must be wrong (maybe in my linker script), but I cannot figure out what. Do 
anybody have a hint.
