Re: Global variables not initialized properly (Win CE 5.0)

You're probably accessing the variable too early. You have to wait until
after the KernelRelocate function has been called.

Hello all,

I developed a RAM-based application and was able to build a debug image
successfully. In it I initialize several global variable to set values,
ie.

#define S3C2412_REG_GPCDAT 0x56000024
unsigned long * gpcConData = (unsigned long *) S3C2412_REG_GPCDAT;

However, during execution my global variable, *gpcConData, is not set to
the
correct value, 0x56000024. Instead it's a seemingly random number. Upon
inspection of the S-record file (EBOOT.SRE), I see that the linker is NOT
initializing that value at all. My fix for the time being is to perform
the
initialization in executed code. This applies to all user-defined global
variables. Obviously, this isn't acceptable as I don't want to have to
initialize all my global variables during run-time.

Is there a env var, flag or setting that must be changed to force the
linker
to actually initialize globals with the value I set them to?

Please help!

Thanks,
Emile

The platform is a Samsung S3C2412 ARMV4I-based uC with 32MB SDRAM mapped
at
0x3000 0000. I am using Platform Builder
