Hi
How can I place of special group of variable in a determined part of memory?

[cwunder]

The method to do this depends on the tool chain being used. Typically you would create a section at a location in the linker file and use this section in your code when defining the variables.

Thank you for your reply...
Do you know any examples which i can study or any docs for high-tech?
If not, then also ok
Many thanks

For the HIghTec,

As an example to locate a data struct that you created. Located at an absolute location in global LMU memory (non-cached at 0xB0040000) on a TC39x device.

In the LSL file create a section:

SECTIONS { .myData   (0xB0040000) : { KEEP (*(.myData )); } > lmuram_nc  }

Then in your source code declare it:

myStruct_type  __attribute__((section (".myData "))) myDataStruct;
