[AW60]

Hi all,

I am usinh AW60 with codeworrier. I have defined  a gloabal variable in .C file and reading this variable in other .c file. But when i simulate this program with codeworrier i get above error. What is reason for tis error & how can i solve it?

Hello,

As the message says, the debugger is warning that you are attempting to read a memory location that may contain random garbage because it has not yet been initialised.  This suggests that you may have disabled ANSI initialisation of global variables when you created the project.  Your code will then need to explicitly initialise the variable before attempting to read.

This only applies to simulation mode.  For the real hardware, the read will return the garbage value.
