Board : iMX6 Quad with 1GB RAM
Build environment : Yocto-Zeus
Kernel : 5.4

Hi,

I am using iMX6 Quad 1GB board with x-wayland.
I have observe the 220MB RAM usage at starting without launching any application.
I would like to reduce RAM consumption.
What could be the possible approaches to do that?

Hi @himanshubhavani ,

I hope you are doing well.

One can try removing unused reserved memory nodes in the device tree if present.

One can add the below option in the kernel configuration.

CONFIG_CC_OPTIMIZE_FOR_SIZE=y

Please try to get more information about various processes using the below command.

# top
# ps aux

However, with Wayland build it seems to be normal memory usage.

Thanks & Regards,
