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.
Carsten
