TMS320F28069: attribute((ramfunc)) this method does not require memcpy like older #pragma method nedded?

Shubham Kant Dubey

Part Number: TMS320F28069

Hi,

If I am using __attribute__((ramfunc)) in new compiler then, do I need to use memcpy calling in main function? Is this attribute automatically append memcpy routines inside startup code?

In older compiler we used to do #pragma CODE_SECTION(".TI.ramfunc"), this require a memcpy to copy data from flash to ram.

Please give your comments.

Regards,

Shubham,

The practice is still required with newer versions of the compiler.

Shubham,

Please check this wiki page: processors.wiki.ti.com/.../Placing_functions_in_RAM
You don't need to call memcpy if use the BINIT functionality.
Let us know if you have further questions - we can connect you to our linker team.

Thanks and regards,
Vamsi
