Hi
I use Flowcode 4.5.18.74 Professional and now try to get Flowkit working,...........But.

When I load a program directly into the proc. (16F877A)(via EB006 V3) and PPP3, without the Pickit , everything is working fine.
The program works on the target and no errors while programming.

Now I switch the (new) PicKit between the pc and de EB006, then i can't program the PIC, and the file seems now to have more ROM words !!!! (see screenshot attachment)

And when I program without the PicKit in between, and after programming, try to put the PicKit between for debugging, also an error.

It seems that the ICD puts extra software in the ROM causing this trouble ???

What can I do??

B6 and B7 are free for debugging.

I'm sorry but I ask myself, is this equipment the right choice to work with, because it cost a lot of time to get these new debugger work, before I can use it.
And difficult to find an quick solution, only by forum. more for hobby but not for commercial work.

Hope somebody can help me out.

Regards Jan

Hi Jan,

It looks like your program is such that enabling the ICD is overflowing the stack limitations of the microcontroller. You can try and switch to a software stack model using the information posted here and hopefully this should help.

Hi Jan,
As you correctly stated, there is not enough room on the target device to run both your code and the additional code that ICD requires to function.
You can try reducing the Breakpoint count and call stack depth, but considering the target device is overfilled 11.4% = 938 words, not sure if it will help or not.

Ben is the authority on usage of Breakpoint count and call stack depth, and I'm not..sorry

Could your code be made any more efficient?
Perhaps if don't mind posting code, we could take a look for you?
No promises of course, as it may be as efficient as it can be?

The only other option is to use a microchip selection tool to find a more suitable device, which can be use just for testing purposes:

Or

Or

Then when all is working you could go back to a smaller cheaper device with out ICD enabled, if you require a few of them.

The corruption part, Ben knows far more about that then I do.
