How to get log from the DSP in DM8168 ?

Hello,

Make sure that you make this change in the file /examples/ti/omx/demos/dm81xx/DspAppMain.cfg, add the following at the end and recompile DSP firmware:

/* ====================================================== */
/* ================ Logger configuration ================ */
/* ====================================================== */
var Defaults = xdc.useModule('xdc.runtime.Defaults');
var Diags = xdc.useModule('xdc.runtime.Diags');
var Main = xdc.useModule('xdc.runtime.Main');
var Load = xdc.useModule('ti.sysbios.utils.Load');
Load.hwiEnabled = false;
Load.swiEnabled = false;
/*
* Create a static task for M3 UIA configuration
*/
var taskParams = new Task.Params();
taskParams.instance.name = "uiaServerTask";
task_params.stackSize = 0x6000;
Task.create('&uiaServerTask', taskParams);
 /*
 *  Create a LoggerSM instance and use it for all logging. Make sure it is at the same section
 for all cores (DSP, Video, VPSS) and not put anything else in "LOGGER_SM". All cores will
 share this same memory. All cores must have numCores and sharedMemorySize be the same value.
 */
var LoggerSM = xdc.useModule('ti.uia.runtime.LoggerSM');
LoggerSM.partitionId = 0;
LoggerSM.bufSection = ".loggerSM";
LoggerSM.sharedMemorySize = 0x00100000;
LoggerSM.numPartitions = 3;
LoggerSM.decode = true;
LoggerSM.overwrite = false;
var statusLogger = LoggerSM.create();
 /*
 *  Make sure the section is in LOGGERSM (defined in
 *  ti\omx\build\MemSegmentDefinition.xs). Also make sure it is a NOLOAD
 *  section. This avoids wiping out another cores logger memory when more
 *  than one cores is loaded.
 */
Program.sectMap[".loggerSM"] = new Program.SectionSpec();
Program.sectMap[".loggerSM"].loadSegment = "LOGGER_SM";
Program.sectMap[".loggerSM"].type = "NOLOAD";
 /*
 *  Plug the LoggerSM logger into LoggerCircBuf. All STATUS events
 *  and logs from Main will go to the LoggerSM instance
 */
LoggerCircBuf = xdc.useModule('ti.uia.runtime.LoggerCircBuf');
LoggerCircBuf.statusLogger = statusLogger;
LoggerCircBuf.filterByLevel = true;
LoggerCircBuf.moduleToRouteToStatusLogger = "xdc.runtime.Main";
 /*
 *  Use LoggingSetup which uses UploadMode_JTAGSTOPMODE as the
 *  default. Increase the Log sizes.
 *
 *  Configuration done by the application is still honored (e.g. setting
 *  up the common$.diags mask).
 *
 *  Please refer to the ti.uia.sysbios.LoggingSetup module for more
 *  details and configuration options.
 */
var LoggingSetup = xdc.useModule('ti.uia.sysbios.LoggingSetup');
LoggingSetup.loadLoggerSize = 1024*10;
LoggingSetup.mainLoggerSize = 1024*1024;
LoggingSetup.sysbiosLoggerSize = 32768*10;
 /* Use the a transport to move the records to MCSA */
LoggingSetup.eventUploadMode = LoggingSetup.UploadMode_NONJTAGTRANSPORT;
 /* ================ UIA configuration ================ */
/*
 *  The default is to have a single core. This example is a multi-core
 *  example. So UIA must be told to act accordingly.
 */
var ServiceMgr = xdc.useModule('ti.uia.runtime.ServiceMgr');
ServiceMgr.topology = ServiceMgr.Topology_MULTICORE;
ServiceMgr.transportType = ServiceMgr.TransportType_NULL;
 /* The HOST is the master UIA processors */
ServiceMgr.masterProcId = 3;
 /* The application is using the UIA benchmark events. */
var UIABenchmark  = xdc.useModule('ti.uia.events.UIABenchmark');
 var UIAStatistic = xdc.useModule('ti.uia.events.UIAStatistic');
 /*
 * Turn on ANALYSIS for benchmark events and others for Log_print used in app
 */
/* RUNTIME_ON Diags masks */
Main.common$.diags_USER1 = Diags.RUNTIME_ON;
/* RUNTIME_OFF Diags masks */
Main.common$.diags_ANALYSIS = Diags.RUNTIME_OFF;
Main.common$.diags_ENTRY = Diags.RUNTIME_OFF;
Main.common$.diags_EXIT = Diags.RUNTIME_OFF;
Main.common$.diags_USER2 = Diags.RUNTIME_OFF;
Main.common$.diags_USER3 = Diags.RUNTIME_OFF;
Main.common$.diags_USER4 = Diags.RUNTIME_OFF;
Main.common$.diags_USER5 = Diags.RUNTIME_OFF;
Main.common$.diags_USER6 = Diags.RUNTIME_OFF;
Main.common$.diags_USER7 = Diags.RUNTIME_OFF;
Main.common$.diags_INFO = Diags.RUNTIME_OFF;
Main.common$.diags_USER8 = Diags.RUNTIME_OFF;
/* Turning Semaphore logging off */
Semaphore.common$.diags_USER1 = Diags.RUNTIME_OFF;
Semaphore.common$.diags_USER2 = Diags.RUNTIME_OFF;


You should rebuild the example also and execute ./loggerSMDump.out 0x9e400000 0x100000 dsp.

Make sure that you have copy/paste the  DSP firmware which you could find here ti-ezsdk/component-sources/omx_05_02_00_48/bin/dm81xx/bin/ti816x-evm
after the recompile.

Let me know the result.

Margarita,

thanks for your answer. I have done the modifications on the DspAppMain.cfg before, with no effect. What I did not realize is that the DSP executable was not being copied to the appropriate location, even after I issued a make omx_install. I then copied the executable file from the directory you indicated into the directory on the target /usr/share/ti/ti-media-controller-utils/. I also renamed the file (which had a _debug extension) to the name dm816x_cxdsp.xe674, and moved the original files dm816x_cxdsp.xe674 and dm816x_cxdsp.xe674.gz to a different directory. Now I am seeing the log file output.

Thanks again!
