    IDE: STVD 4.10

    Compiler Cosmic 4.2.7.

    Thanks

    look for the -f option in the linker section of the manual: I'm not sure if STVD allows to manage this via the graphical interface, but, worst case, you can edit the .lkf file by hand.

    Regards,

    thanks _luca.

    Solution:

    it is possible to set this option in

    Project->settings->[tab]Linker Category ''input'' at the end of the section name if -m set. and add -f0x83 (filling with trap opcode)

    We obtain this line in lkf file

    +seg .const -b 0x8f00 -m 0xf100 -n .const -it -f0x83
