CCS Showing different values in debug than program output

Westin Sykes

I am working on a bootloader, and am going along with the example bootloader for some of the basics of it. I have my .cmd file set up to execute the most of the code from RAM (BL_SRAM), AND i AM USING load_start, run_start, and size to know how much needs to be copied from flash. I am using extern to pull the values from those in, and the value is what I expected in the debugger expressions window, but is not correct when I print it out. Does anyone have any suggestions as to why this is happening?

Thanks,

Westin,

I'm not sure if this is the root cause of your problem, but in order to have the printf working correctly, it is necessary to add in your linker command file the following in the SECTIONS part:

.sysmem : {} > SRAM

Please have a try and let me know.

I did that and found no change. My Print function is not exactly the same as printf. It has the same usage, but sends the text through SCI rather than to the debugger.

Thanks,

Westin

I figured out what was going wrong. The value I was trying to get was a reference to the external value. I'm not sure why CCS was giving me the value it was.

Thanks for the quick response.
