SigmaStudio+ LibraryIntegration examples is not running properly

Question

Hi Sir, 
 Based on "C:\Analog Devices\SigmaStudioPlus-Rel2.1.0\Target\Examples\LibraryIntegration\ADSP-21593, I created two SigmaStudio+ for ADSP21593 project. I found that one of the files exported by SigmaStudio+ was not working when added it to the examples project. Attached are two exported header files, SigmaStudioPluse_Export_NOK_16CH.zip does not work properly. I compared these two files in detail. The biggest difference between them is the size of "Program Data and Parameter Data". The Program/Parameter Data of SigmaStudioPluse_Export_NOK_16CH exceeds 5000 bytes. 
 I guess this data size is too large, causing memcpy to go out of range. How do I copy it? Do I need to copy memcpy many times? How to set the destination address of memcpy? 
 /* copy code from schematic source file */ 
 memcpy ( oSSnMemMap.pMemBlocks[1]->pMem , PROGRAM_DATA_SH0_DIFFDXESCHEMATIC_1_Data, PROGRAM_DATA_SH0_DIFFDXESCHEMATIC_1_SIZE ); 
 
 /* copy parameter from schematic source file */ 
 memcpy ( oSSnMemMap.pMemBlocks[5]->pMem , PARAMETER_DATA_SH0_DIFFDXESCHEMATIC_1_Data, PROGRAM_DATA_SH0_DIFFDXESCHEMATIC_1_SIZE );

SigmaStudioPluse_Export_OK_2CH.zip SigmaStudioPluse_Export_NOK_16CH.zip

could you please check whether the binary data in the source file and data copied into the memory location are same? you can use memory browser to export the data and verify.

Hi, 
 We are able to run the schematic (SigmaStudioPluse_21593_8IN_8OUT_Integration_Test2_NOK.ssprj) without any issue using ADSP-21593 library integration project which is available in the SigmaStudioPlus2.1.0 installation path. We will check with your shared target application and update you. 
 Thanks

Hi Johnny, 
 Please find the suggestions to debug the no audio issue, 1. Verify whether the Bit clock, LR clock and data available at the hardware DAI pin's assigned. 
 2. Verify whether proper signal routing done in the software for Bit clock, LR clock and data pins to the SPORT and external ADC/DAC/A2B transceiver. This routing should be proper to get the expected output. 
 3. "Level detector" blocks can be used in SigmaStudio schematic to see whether signals are received. Based on this signal information in level detector, you can focus on which pin not getting audio. 
 4. If you are using A2B application please make sure all clock edge settings are fine with the A2B transceivers in the schematic. 5. If you are using 2 core processing you must add a schematic for core2 as well. I observed your core2 schematic seems empty, you need to connect 8 Ch input to 8 Ch output pin in core2. The default application example is for dual core serial processing, so both cores should have schematic at least Input and output module connections. 
 6. If you are using single core application you can use Single core processor or in dual core processor disable the second core in core settings. 
 you can find the example schematic from, wiki.analog.com/.../adsp-sc5xx_2_sh_core_demouc_example.zip
