Have you some code examples to run a I2S connection (SPORT) with BF548 ?
The VDSP code examples for the 548 contain an audio loopback to the AC'97 codec through the SPORT, using device drivers. While this is not an example of I2S mode, there are other device drivers (such as the adi_ad1836) which uses I2S or TDM mode on the SPORT. More information on system services and device drivers can be found here:
If you are looking for an example using I2S on the SPORT that does not use system services / device drivers, I recommend you look at the BF537 and BF533 stereo loopback examples (path for the BF537 example in VDSP 5.0 below):

The configuration of the SPORT can serve as a guide to setting up the SPORT on the BF548, along with the second volume of the BF548 hardware reference manual, located here:
