Static memory buffer size


Specify the memory buffer size for external mode communication.

Category: Code Generation > Interface


Default: 1000000

Enter the number of bytes to preallocate for external mode communications buffers in the target.


  • If you enter too small a value for your application, external mode issues an out-of-memory error.

  • To determine how much memory to allocate, select verbose mode on the target. That selection displays the amount of memory the target tries to allocate and the amount of memory available.

  • If parameter Transport layer is set to XCP on TCP/IP or XCP on Serial, you can use this parameter to specify the size of XCP server memory allocated for signal logging.


Selecting parameter Static memory allocation enables this parameter.
