Power Mode Switch Application in IMX8QM-MEK

[vinothkumars]

Hi All,

I done the following for build the power_mode_switch demo application with Arm Cortex-M4 on IMX8QM-MEK. power_mode_switch demo application is running but android is not booting.

Hi VinothS

one can look at link for creating image for i.MX8

i.MX8 Boot process and creating a bootable image 

and build steps in Android documentation

i.MX Software and Development Tools | NXP 

Make sure that used release supports i.MX8QM (supported processors are

described in Release Notes) and SCFW version (also described in Release Notes).

Then try to rebuild all image from scratch.

Best regards
igor

Thank you Igor for the reply.

Do you have any user guide to power mode switch application in IMX8 series ?

Is power mode switch application controlled the Application Processor ?

Thanks & Regards,

VinothS,
