iMX RT1020 EVK routing to J17 18 19

Is it possible to Route SAI (I2S or TDM) lines to these connectors

on the EVK board using the internal router?  Need to get AUDIO IO in multiple channels connected to the EVK board easily.

Hi Danman,

   In fact, to RT1020, the SAI related pin is fixed, you can check the RT1010 reference manual,  chapter 9.1.1 Muxing Options.

   Eg,

So, you need to check which detail SAI module you want to use, and check the related SAI module pins in the J17, J18, J19 or not.

MIMXRT1020-EVK board using the SAI1, and connect it to the codec U10, WM8960 chip.

  In fact, even the related SAI module didn't connect to the J17, J18, J19.

I think you still can connect the wire to the R83,R85, R87,R88,R89,R90, the related SAI pin, just need you to solder the wire by yourself.

 

Wish it helps you!

If you still have questions about it, please kindly let me know.
