Hi list,
now I had a little bit time to start a task, which was in my inbox for a
longer time: a suggestion from Petr to read and use controller signature.
I've started now to implement this. If simulavr commandline application
read a given elf file, it reads now too signature, fuses and lock bits
area, if available. In this first step it compares then signature from
elf to controller signature, which is selected by "-d" option on
commandline. If a signature is available on elf and not equal to
selected controller signature, it aborts.
One question is, is there a need to disable this feature? (maybe on
avr-libc tests?) Of course, some simple programs, which are compiled an
linked for example for mega16 will also work for mega32. On the other
hand, I don't want to implement useless "features". :-)
In the moment, this code resides in my repository, if someone wants to
review it or try it, I can upload it in a development branch. Please let
me know, if I should do this.
Planed next step is, to extend (E)LPM instruction to read - depending on
controller - fuses, lockbits and signature by program.
cu, Thomas
