CWv8 byte pointer

admin — Tue, 23 Jan 2007 22:11:26 GMT

I use CW for 56800E. In the following line I try to store address in bytes of name2 into var_addr (e.g. if name2 address 0x13b -> var_addr=0x276).
const int var_addr = (const int)((byte*)&name2);
In version 7.3 this code works fine
In version 8 (byte*) convertion seems to be ignored and in var_addr is word pointer (i.e. 0x13b)
Is this a compiler bug or I missed something?

I contacted freescale support and received the answer.
This is a problem of compiler. It appeares if we initialize the variable for address inside a function.
So, wait bug fixes.
Also i get the following (temporarily) solution:

We must define global variables outside a function, but we can initialize them inside a function.

I'll be careful now
