Problem with McASO PSPdriver example on C6748

Hi everybody,

I want to run the McASP example project of pspdrivers_01_30_01. My problem is that  after the debug lunch the program starts, but never hit the main-function.

I ajusted the memmory adresses and lengths in the DSP/BISO configuration tool to the TMDSEVML138-A from logicPD with the SOM-C6748.

 

FYI: I'm using the CCSv4.2.4, Code Generation v7.0.4, DSP/BIOSv 5.41.10.36 and pspdrivers_01_30_01.

 

I hope you are able help me.

Greetings

Stephan

    Then where the pointer goes?

    You can try to open the application file and put a break point and execute the application. Eg: If you are using the audio application, then put the breakpoint in the function "Audio_echo_Task()" and run the app.

    Please make sure that all the environment variables are set properly.

    Make sure that the CCS has detected your PSP otherwise locate the source file manually (when CCS loads the executable).

    First, try with the prebuilt binary which comes with the PSP and then go for customizing and building application/driver.

    Thanks and Regards,

    hi Sandeep,

    thanks for your quick reply.

    The pointer goes at the beginning, after the debug lunch, to the c_init00: at 0xC0046E60 (I adapt the memory for the DDR to the TMDSEVML133-A [0xC0000000 and length 0x80000000]) and runs then to 0xC0043F90 (Disassembly: 1CE6    SPKERNEL   0x1551473536,7398).

    At this point of the program get stuck and does not move.

    I'm not sure if I have the time today to try your hints, but I hope I can try them next week.
