Hi @ryan_chen!
Thank you for contacting NXP Support!

All the examples and documentation with that SDK can be downloaded on the next Link:

https://www.nxp.com/products/processors-and-microcontrollers/arm-processors/i-mx-applications-processors/i-mx-6-processors/i-mx-6ull-single-core-processor-with-arm-cortex-a7-core:i.MX6ULL

If that doesn't exist the example you are looking for is unavailable.

Sorry for the mistake!

Best Regards!
Chavira

I would also appreciate some example. I found various Device tree esai nodes e.g. (e.g. imx6ull.dtsi in linux-imx fork) but it doesn't work for me. It fails with fsl-esai-dai 2024000.esai: failed to init imx pcm dma: -517 which means to defer the driver loading as it struggles to register DMA channel. There is no documentation and no example to device tree for esai node.
