SPORT routing in SC589

Hi Alon,

Please refer the below Ezone thread, which has many bare metal code example for SPORT and its SRU configuration, hoe this helps.

ADSP-SC58x/2158x SPORT: Example codes

Additionally refer the Digital Audio Interfaces chapter in the ADSP-SC58x hardware reference manual for better understanding.

You could also make use of 'SRU configuration' Add-ins in the CCES (under system.svc in the project explorer ). This add-in provides a simplified method of configuring the SHARC Signal Routing Unit (SRU).

Thank you Jithul for the reply.

As I posted originally, I already went through the examples you suggested, the HRM and the CCES help on the SRU configuration add-on. Still have a problem with the FS signal. As I described, we used the routing as in the HRM, figure 33-10, - the default routing. The only change, if at all is that we use external clk and internal FS. I couldn't find a way to do that, especially when I cannot find any documentation of the signal SPT0A_FS-PBEN_O.

Please help me with this.

Thanks, T.

Hi Alon,

Sorry for the delayed response. See the SRU configuration given below

/* Connect the SPORT0 ACLK to DAI_PIN03 (if SPORT0 CLK is internally generated) */
SRU(SPT0_ACLK_O, DAI0_PB03_I);
SRU(SPT0_ACLK_PBEN_O, DAI0_PBEN03_I);

/* Connect the DAI_PIN03 to SPORT0 ACLK (if SPORT0 CLK is supplied form externally) */
SRU(DAI0_PB03_O, SPT0_ACLK_I);
SRU(LOW, DAI0_PBEN03_I);
SRU(LOW, DAI0_PB03_I);

/* Connect the SPORT0 AFS to DAI_PIN04 ( SPORT0 FS is internally generated) */
SRU(SPT0_AFS_O, DAI0_PB04_I);
SRU(SPT0_AFS_PBEN_O, DAI0_PBEN04_I);

/* Connect the SPORT0 AD0 to DAI_PIN01 */
SRU(SPT0_AD0_O, DAI0_PB01_I);
SRU(SPT0_AD0_PBEN_O, DAI0_PBEN01_I);

/* Connect the DAI_PIN02 to SPORT0 AD1 */
SRU(DAI0_PB02_O, SPT0_AD1_I);
SRU(LOW, DAI0_PBEN02_I);
SRU(LOW, DAI0_PB02_I);

I have also attached a driver based SPORT loop-back example for your reference.
