Hi,
thanks for the tips.
My application is quite big (60kByte binary) and I have one recursive
function so this needs to be reentrant.
That was the reason why I used the stack_auto.
I will have a look if I can use the tiny printf function.
Can I use small with 64k xdata and 64k code?
Thanks,
Andreas

Using Tomcat but need to do more? Need to support web services, security?
