Hi ，

I  want to know that about IMX8M mini.

1.I see the SAI1(3.3V ) also used for boot CFG .If i change the  power of SAI1(3.3V )  to  SAI1(1.8V) ，also to every part about SAI1.

Does the boot CFG work normal  ? As i need use the SAI1 works at the level of 1.8V  ranther than 3.3V.

thanks a lot !

According to the i.MX8MM datasheet. There is no problem if you use 1.8 to supply the SAI1. It supports voltages from 0V to 3.8V
