Dear All,

EMC design How to set TRAP instruction on all unused flash code?

I want to fill unused flash memory with 0x83 (Trap instruction)

How it is possible with:

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
