CCS watch windows problem?

Chi Min Tseng

Hi, I write a code like this

typedef struct _ansLSQ_struct_
{
double level[ADCCHNO];
double bmatrix[ADCCHNO];
double ydata[NUM_POINTS];
double xdata[NUM_POINTS];
} ansLSQ_struct;

ansLSQ_struct *ansLSQ;

main()

{

...

}

When I in debug mode, the expressions window like this:.

I want to see the xdata[n] value, but I can't see.

I don't know what's the'"Error: Memory map prevented reading 0x92834984@Data" mean?

Can anyone help me? Thanks.

That error means the debugger was trying to read memory that the debugger memory map says is not readable.

But the error you are getting is confusing because it looks like the array xdata starts at 0x834984 but when you expand the array to view the elements, it pre-pends a '92' in front of the address to make it an invalid address. It looks like a bug with CCS. What version of CCSv5 are you using? If you are not using CCSv5.5, can you upgrade to it and see if that helps?

Thanks
