Issue with integrating NDK/NSP and PSP driver programs.

Other Parts Discussed in Thread: OMAPL138

Hi,

I am using following :

-OMAPL138 EVM

-DSP/BIOS v5

-CCS v4.2

-XDS100v2

-pspdrivers_01_30_01

-edma3_lld_01_11_03_01

-NDK 2.20.00.19

-NSP 1.00.00.09

  I am tryng to create an application, which captures audio, encode it and send to another omapl138 evm through ethernet then decode the data and play it. For which I integarted the 'audio sample application' in PSP driver examples and 'helloworld program' in NDK. I am using only the DSP core, and loads the program into DSP using  XDS510 USB JTAG Emulator and CCS4.

But my receiver side application hangs afte few seconds of running. In OMAPl138 forum I read that when using XDS510 USB JTAG Emulator,one guy faced similer issue and he solved the problem by flashing the application into DSP. So instead of using XDS510 USB JTAG Emulator, I used the XDS100v2 emulator. Now my programs runs more than 5 minutes,but the hanging problem is still there. 

Is it the problem in using emulator for running the application ?. Or with integration of configurations for PSP and NDK  sample programs ?. 

Please help me to solve the problem.

Thanks in advance.
