Hi Ti experts,

 

I have followed the instructions in the document "build/run instructions for Codec engine Examples" attached to the codec engine.
After successfully building all the examples, servers etc.. I tried to run the examples speech_copy1 and universal_copy using remote server DSP according to the instructions.
The examples are not running, I recieve the following error message:

Root @ Arago :~ /Codec_engine/speech1_copy #./app_remote.xv5t-p dsp-s xe674

[T = 0x0000192d] [TID = 0x400f1000] xdc. runtime. Main: [+ 2] Main> welcome to app's main ().

[T = 0x00001ee8] [TID = 0x400f1000] xdc. runtime. Main: [+ 1] app-> application started, procid DSP enginename remote_copy_dsp input-file./In. dat out.

[T = 0x00002d64] [TID = 0x400f1000] xdc. runtime. Main: [+ 1] app done.

 

Can anyone please help with this?

 

Thanks,
Gabi

  Hy

   

  Try to run

  Root @ Arago :~ /Codec_engine/speech1_copy #./app_remote.xv5t-p dsp-s xe674
  

   

  With ce_debug = 3 and make a. log file of the debug messages like:
  

  Root @ Arago :~ /Codec_engine/speech1_copy # ce_debug = 3./app_remote.xv5t-p dsp-s xe674
  | Tee filename. Log

  And post the. Log File

   

  Regards

  Hi wendelin,

  After running with ce_debug = 3 I saw that the DSP executable name shocould be all_dsp.xe674, the DSP executable file was created in a different name so I renamed it to all_dsp.xe674 and now target stucks.

  Please see attached file.

  6758. err1.log

   

  Thanks,

  Gabi,

  From your trace, it looks like syslink's ipc_control (loadcallback...) failed:

  [T = 0x00150c73] [TID = 0x400assertion at line No: 301 In/home/Gabi/z3-DM8168/z3-netra-RPS-20111017/ezsdk/component-sources/syslink_2_00_02_80/packages/Ti/syslink/utils/hlos/knl/Linux /.. /.. /.. /.. /.. /.. /Ti/syslink/IPC/hlos/knl/Linux/ipcdrv. c:

  But, unfortunately, this trace doesn't indicate why the failure is occurring. cocould you please try enabling syslink trace? You can do this as follows:

  Insmod syslink. Ko trace = 1 tracefailure = 1 traceclass = 3

  This will hopefully give us an idea as to why ipc_control () is failing.

  Best regards,

  Janet

  Gabi,

  According to your log, the symbol _ ipc_resetvector cocould not be found:

  T = 0x00153713] [telfloader_getsymboladdress: symname [_ ipc_resetvector]
  
  Id = 0x400f4000] T *** loader_getsymboladdress: failed to get the symbol address!

  Cocould you check the map file for all_dsp.xe674 (in servers/all_codecs/package/CFG/bin/ti_platforms_evmti816x), and verify that the symbol _ ipc_resetvector exists? Also cocould you provide a log without ce_debug = 3, so that just the syslink trace is shown.
  The codec engine trace is interspersed with the syslink trace, making it harder to read, and I 'd like to compare your trace with mine.

  Thanks,

  Janet

  Hi Janet,

  _ Ipc_resetvector exists in the file all_dsp.xe674.map please see atached file.

  7433.all_dsp.xe674.map.txt
  

  Also I have attached log file without ce_debug = 3.

  3286.err.txt
  

  Thanks,

  Gabi,

  According to your map file, it looks like the DSP entry point is at the address 0x995d7800:

  Entry Point Symbol: "ti_sysbios_family_c64p_hwi0" Address: 995d7800

  But the error log indicates the address 0x8b033100 for the entry point:

  Dload: ELF File Header entry point: 8b033100

  So it looks like the map file you sent does not correspond to the map file of the DSP executable that syslink is attempting to load.

  Cocould you please check again for the correct map file?

  Best regards,

  Janet

  Hi Janet,

  The example is working OK now, thankyou very much for your help, your answer helped me to find the correct DSP executable file, which its name is all_dsp.xe674 and it is found in

  Ezsdk_xx_xx_xx/component-sources/codec_engine_xx_xx_xx/examples/Ti/SDO/CE/examples/servers/all_codecs/bin/ti_platforms_evmti816x/

  And not what I was doing mistakenly which was to take the DSP executable named app_local.xe674 from where the executables were created for the example speech1_copy and rename it to all_dsp.xe674.

  Thanks,
  Gabi
