Dear NXP team,

We are working on Power Management on i.Mx6 Dual Lite SODIMM platform.

We would like to test the total current consumption in suspend mode. So we put the device to suspend mode

using mem command(echo mem > /sys/power/state)

It enters suspend mode successfully when we wake up(touch is the wake up source). The yocto x11 Desktop is getting corrupted. I have attached the image for reference.

Image 1 is the actual image and Image 2 is the corrupted desktop image after suspend.

When we kill the matchbox-desktop x11 application then there is no issue. system can go into suspend mode and can resume without any corruption on LCD.

Please help us with his. Give suggestion ASAP as we are struck up with this

Awaiting for your response.

Thanks & Regards

Sarjoon

Hi,

This look like a memory issue, Please check our suspend/resume code in mx6_suspend.s file, and also check your DDR configuration.
