Hello Community,


We are developing custom board with i.MX280 which does not use many of the peripherals.

Since we do not need these peripherals, we want to disable these functions.

Followings are the questions I'd like to ask you.



For most of the peripherals, it looks SFTRST or CLKGATE disables the function.

In this case, is setting CLKGATE to 1 the right way to disable the function?


(2) About Ethernet Controller

For Ethernet Controller, we could not find a clue to disable the function.

Is there any way to disable it?


By the way, does disabling peripherals lower power consumption?

We are trying to minimize the power consumption, so any advice or suggestion to achieve it is also welcome.


Thank you in advance,
