different results when running code from release and flash

Hi EVS,

Did you refer to this example for the flash configuration: C:\ti\controlSUITE\device_support\f2806x\v151\F2806x_examples_ccsv5\flash_f28069
I doubt the linker section.

Thanks for the reply.

Yes I looked at that. It isn't that complicated. And maybe there a linker difference between release and Flash but in CCS it is really user unfriendly to compare both properties. I always wonder if I'm the only one who hate eclipse because they really tried to make everything over complicated.

Try to replicate the linker settings from example code and let us know what you observe.

Hehe :) It does feel sometimes!

I didn't find any difference:
I also checked the compiler difference and changed the link order. and you have to manual change it first before it is included in the compiler --opt_for_speed=2 and I think that solved it.



Now my program works fine in flash when I upload it and start it from CCS. But doesn't work correctly when the debugger is removed. How strange. But first I have to rule out that it isn't a hardware issue somehow.

Are you sure the code is getting loaded to flash? Can you see the long erase operation?

Yup yup... do check that too.

Yes the code runs but the code doesn't work correctly. At this point I got different results when I run standalone in flash or with the debugger connected.

That's strange. Also, have you set the heap and the stack size to 0x2000?

I don't think that it is a hardware issue. Maybe a Spintac library issue.

If I run my flash program with the CCS and the programmer attached. The program works fine.
If power cycle and I remove the programmer the program runs ,I have I/O but my servo motor won't work.
How strange and nearly impossible to debug?
So when the debugger environment is loaded what is copied to RAM in the 28069?

evs,

You could try debugging something like this:

• power cycle
• connect the debugger
• load symbols only - this will not load the program, but only symbols so now you can debug

In this case you may be able to see what is going wrong.

Another thing to check is the .map file.  Make sure no initialized sections are in RAM.

Hi Evs,

Has the problem been resolved? Can I close the post?

Lori

I asked the question again at TI C/C++ Compiler Resources in the hope to get some more sophisticated answer than: power cycle or connected the debugger.
