Hi,

if you have the problem with several functions there's probably something wrong in your program: please post more details.

However, we recently fixed a small problem with the header of memcpy (in string.h): if you use the free version you can get the latest (fixed) here: http://www.cosmicsoftware.com/download_stm8_32k.php

If it's a full version, please contact us and we'll set up a private download for you.

Regards,

Luca (Cosmic)

Hi Luca,

I spent some more time working on this and I had taken out every function call but one (strcat()....just appending a short string to the end of a UART buffer). During debug, I found that my program would still hang on this function call.

I ended up changing my memory model to ''Long Stack (+modsl)'' and it seems to work now. Now I have many calls to strcpy() and strcat() in place with no problems.

How recent was the fix made to the memcpy header? I'm using the free version....I downloaded it on 3/4/2010.

Thanks!

Are you sure that your strings are correctly terminated?

A complex system that works is invariably found to have evolved from a simple system that worked.
A complex system designed from scratch never works and cannot be patched up to make it work.
