ADSP-21569-SOM example

1. The EV-21569-SOM manual (Rev 1.0) mentions the EV-21569-SOM BSP, but the current BSP provided by the official website, but the SOM is equipped with the EV-SOMCRR-EZKIT carrier board
Is EV-21569-SOM BSP available with EV-SOMCRR-EZKIT carrier board version?

2. EV-21569-SOM handles I2S and SPDIF, whether there is a Sample Code

Thanks You
