when I run:

./audioSoc_gpp audioSoc_dsp.out davincieffect_clip.pcm

Stop and lock at:

LDRV_DRV_handshake (IN ProcessorId dspId, IN DRV_Handshake hshkCtrl)
{

...

(DSP_SUCCEEDED (status)) {

/* --------------------------------------------------------------------
* Handshake with the DSP
* --------------------------------------------------------------------
*/
status = (drvState->interface->handshake) (dspId,
drvState->linkDrvId,
hshkCtrl) ;

....

}

Why? Who can help me to resolve it?

Thanks very much!

After run :

./audioSoc_gpp audioSoc_dsp.out davincieffect_clip.pcm

I cann't get any log from audioSoc_dsp.out! After PROC_load, the file

audio-soc-example_1_00_00_03/dsp/evmOMAPL138/main.c will run, right?

Hi Changsheng,

Thanks for your post.

Yes, audio-soc-example will run for sure but kindly follow the below steps to run this example:

The audio SoC needs to be built in the linux environment as its build has been setup for the make environment and not the CCS environment. This example is integrated into the linux software development kit for the platform, which is a self contained packaged with integrated build environment (make based not CCS based). In order to build this demo follow the steps below :

1. Download DVSDK 4.03 from here on Ubuntu 10.04

http://software-dl.ti.com/dsps/dsps_public_sw/sdo_sb/targetcontent/dvsdk/DVSDK_4_00/latest/index_FDS.html

2. Disable ALSA driver from the kernel.

3. Build the linux kernel, DSPlink, CMEM (instructions software developers guide in doc folder of SDK)

4. Build the Audio soc example and install binaries to filesystem.

5. Flash ubl and uboot on the platfrom. Run setup.sh from DVSDK to setup linux boot

6. To run the example look at the instructions in the software designers guide

http://software-dl.ti.com/dsps/dsps_public_sw/sdo_sb/targetcontent/dvsdk/DVSDK_4_00/latest/exports/OMAPL138_Software_Developers_Guide.pdf

Note: In DVSDK this information is documented in Software Developers Guide at section "Running the Audio SOC example"

DVSDK4.x FAQ at section Why do audio_soc_example application on OMAPL138 hung? has more info on this issue.

This is also documented in Release notes of Audio SOC example component. Please refer to the dependencies for the demo in the release notes.

Hope this helps.

Thanks & regards,

Sivaraj K
