CC2650: CCS: "FLASH memory range has already been specified" error when copying a project

Hi Jim,

Did you copy-paste the project in the CCS project explorer environment or in your File Explorer?
When you open the simple_peripheral example in your workspace for the first time did you check the box below?

This box allows you to modify the example without impact on the original one, the SDK one. Thus, you can directly apply your modification in this file, without copy-paste.

Regards,

PS: Make sure all your projects have not the same name.

Hi Guillaume,

I did the recent copy/paste in the CCS project explorer window.  That project builds ok and works as required.  When I copy & paste it to a project with a different name, I get the errors.

I set up the original project a couple of years ago so I don't remember if I if I did it with the "copy projects into workspace" box ticked.

Jim

Does the error still occurs when you copy-paste the project in a new workspace?

It seems that the symbols __STACK_TOP is redefined, but I will need more informations to fix that, could you provide me a screenshot of your project explorer, and the file where the error occurs, please?

Regards,

Yes, when I copy/paste the working project, I get the build errors.

Here is a screenshot of the project explorer:

the error is in the cc26x0f128.cmd file:

Some other related questions:

- is there an app note covering how to gather up only the files used by the simpleperipheral app into a separate CCS project?

- is it possible to release an open-source customization of the simpleperipheral app?

Hi Jim,

It seems to be a linker file error, can you provide me the Linker command file in the properties of your project, General.

Check that this file corresponds to your dedicated copied project.

Regards,

Hi,

There is a procedure to properly create custom CC2650 CCS projects. It's not documented anywhere. I think what you can do is rename the simple peripheral.
