How to modify the _c_int00 address?

 Hi everyone,

      There are two C6678 DSPs on my board . I want to implement data transmission between two DSPs through GbE interface. The GbE interfaces of two DSPs are

connected directly. When I loaded the client_evm6678l.out which is an example project about ndk, an error appears. Then I found the _c_int00 address is in DDR

 space.But DDR on my board can't be used at the moment. So I want to modify the _c_int00 address of the project. Could you tell me how to do it ? Thank you.

Best Regards,

Nuoxi

    Nuoxi,

    The simple answer is that you change the linker command file to use only internal memory, and re-build the project.

    Depending on how the project is implemented, changing the linker command file may require that you change some configuration file to use only internal memory.

    It is possible that the project cannot be implemented with only internal memory, but I suspect that the C6678 does have enough internal memory to support this. You may be limited in the size of data buffers, but it may work if you get it all figured out.

    Sorry I cannot tell you the exact changes to make.

    Regards,
