Constant Strings

MC Potgieter

I have several constant strings that I defined as follows:

const u8 *Stringname = "StringContent";

At some stage if I add one more string, the uC stops working. I have more than enough code memory left so it is not a memory problem.

What could be the problem? Am I doing this the wrong way?
Should I put the strings in a different memory space?

    At least in principle,

    u8 *Stringname = "StringContent";

    requires the compiler to allocate memory to store the string itself, plus more memory to store the pointer to the string.

    On the other hand,

    u8 String[] = "StringContent";

    only requires storage for the text.

    The question is: for a pointer to a const string, is the compiler smart enough to do away with the separate pointer...?
