    Hi!

    I use a ST72331N4. I have a program that can be compiled and linked on my machine. i always have this message: ''lyn : Error 5: No information on start address of class 'rom'''

    In my code i have for the segment rom:

    segment 'rom' ; segment de rom

    DC.B ''Peristop CB20 ''

    DC.B ''N° serie: 000001 Version : 1.1 du 18/12/98 ''

    I don't know where the mistake is. Maybe my IDE is not well configured?

    thank's help

    Check the definition for the rom and vector segments, should be something like:

    segment byte at C000-FFDF 'rom'

    segment byte at FFE0-FFFF 'vectit'

    Regards
