Yu Gao,

There are two early returns in Engine_open(), one if the engine name is not found and one for lack of memory. I'm guessing it's the first error, the server was not build with the audio_copy engine. Would you verify that the server was built correctly.

You can also modify examples/apps/audio_copy/app.c to pass in the address of an Engine_Error (Int) and then print the error value when Engine_open() returns NULL. This would confirm which error it is.

app.c
===================
smain()
{
Engine_Error ec;

Engine_open(engineName, NULL, &ec)

fprintf(stderr, "%s: ec=%d\n", progName, ec);

}

i add the code and the app print

app: ec=1

what's it mean?

server build log is in the file, plz have a look, thank you

Yu Gao,

Engine error codes are defined in Engine.h; ec=1 means the engine name was not found.

#define Engine_EEXIST 1 /**< Name does not exist. */

Studying your build log, we believe that your server is built correctly. The problem must be in the build of app_remote.xv5T. The first place to look is in the remote application's config script. Make sure your config script has the following engine definition.

audio_copy/remote.cfg

var Engine = xdc.useModule('ti.sdo.ce.Engine');
var myEngine = Engine.createFromServer(
    "audio_copy",        // Engine name (as referred to in the C app)
    // path to server exe, relative to its package dir
    serverName,
    "ti.sdo.ce.examples.servers.all_codecs" // server package
);

This will generate a table of engines available in the server. The generated table will be in the following file. Check if you see the following.

audio/copy/package/cfg/bin/ti_platforms_evm3530/app_remote_xv5T.c

static Engine_Desc engineTab[] = {
    {"audio_copy", /* engine name */
      engineAlgs0, /* alg table */
      "all.x64P",  /* (optional) server name */
      NULL,        /* (optional) Link config ID */
      24 /* number of algs in alg table */
    },
    {"local", /* engine name */
      engineAlgs1, /* alg table */
      NULL,  /* (optional) server name */
      NULL,        /* (optional) Link config ID */
      0 /* number of algs in alg table */
    },
    {NULL, NULL, NULL, 0} /* NULL-terminate the engine table */
};

Finally, make sure you clean and rebuild the application *after* you have built the server.

If these suggestions do not help, would you package up your audio_copy folder and attach to this thread. I'll inspect your project for other issues.
Thanks
