Re: [Sdcc-user] Linking on STM8

[Georg O. <ge...@ot...>]

Thanks - after putting the prototypes on the right place the prog 
compiles and in the hex file I see the adresses added in the vector table.

Although it compiles it is not working yet ... investigating further.

I feature request for the is that the unused ISR vector table entries 
are pointing to a function like "while(1);" - at the moment all the 
entries point to 00 00 00 which is the beginning of the RAM - resulting 
in unexpected behavior in the case of an "unwanted" Interrupt.

Also investigating the vector table further - the Interrupt numbering 
seems to be different from IAR. - But I already stumbled upon a this 
issue with IAR before. I think the IAR numbering is strange ...

trying further ...
