I am trying to get the digital (S/PDIF) inputs and outputs of the SC573 evaluation board working with SigmaStudio for SHARC.
I am using SigmaStudio for SHARC 4.6 and have loaded the default demo application DXEs onto the board (the one under C:\Analog Devices\SoftwareModules\SigmaStudioForSHARC-SH-Rel4.6.0\Target\Examples\Demo\ADSP-SC57x\ADSP-SC573) and am using the demo schematic Volume_Mute_Block_SC5xx.dspproj (under C:\Analog Devices\SoftwareModules\SigmaStudioForSHARC-SH-Rel4.6.0\Host\Examples\Sample Schematics\ADSP-SC5xx). I have the board set up (cables, jumpers, switches etc) as per the quick start guide (C:\Analog Devices\SoftwareModules\SigmaStudioForSHARC-SH-Rel4.6.0\Docs) with the exception that the boot switch (SW1) is set to 1 as I have programmed the flash as per the instructions in section 6.1.
I can get the board up and running fine and the analogue inputs and outputs work, and the volume/mute controls work on them, but the S/PDIF digital inputs/outputs don't seem to work at all, and the schematic seems to suggest that they should.
I also have a 21489 eval board running SigmaStudio for SHARC 2.2 and the digital inputs/outputs work fine with its demo code, so the other hardware I'm using for digital inputs/output is definitely working.
Does anyone know how to get the digital inputs/outputs working on the SC573 board? Do I need to change settings in the demo application?
Also, as an aside, does anyone know which way around the red/white RCA connectors for the S/PDIF input/output are? I have tried both ways round just in case, but they are not labelled and given that the analogue inputs/outputs are the opposite way rounds (for the analogue inputs the first input is the top RCA connector, whereas for the analogue outputs it's the bottom) I don't want to make any assumptions.
