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.

./app_remote.xv5T: error: can't open engine remote_copy_DSP

[t=0x00002d64] [tid=0x400f1000] xdc.runtime.Main: [+1] app done.

Can anyone please help with this?

Thanks,
Gabi

Try to run the

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

Wendelin

Hi Wendelin,

After running with CE_DEBUG=3 i saw that the DSP executable name should be all_DSP.xe674, the DSP executable file was created in a different name so i renamed it to all_DSP.xe674 and now the target stucks.

Please see attached file.

6758.err1.log

Thanks,
Gabi

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: (status >= 0) : failed

But, unfortunately, this trace doesn't indicate why the failure is occurring. Could 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 could not be found:

t=0x00153713] [tElfLoader_getSymbolAddress: symName [_Ipc_ResetVector]

id=0x400f4000] t*** Loader_getSymbolAddress: Failed to get the symbol address!

Could 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 could 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

Gabi

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.

Could 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
