About low power mode on mxrt1021

[hiro8235]

Can the low power mode be enabled with an empty ROM?
If so, is there a description of the settings in the IMXRT1021RM?
For example, system idle mode settings.
Thank you.

Hi @hiro8235 

   low power mode enter need to use the code, you can download it to the internal RAM instead of the external flash, I think your mentioned empty ROM is no code in the external flash, right?

   If yes, you can download this SDK code to the RAM, just not do the POR, the low power code will help you enter the low power mode.

\SDK_2_11_0_EVK-MIMXRT1020\boards\evkmimxrt1020\demo_apps\power_mode_switch

SDK download link is:

Wish it helps you!
