Ram is less than half of what's advertised

Hi,

I've got Pico Pro (with the RV1106G2 chip). Why do I have only 55 MB of ram? What is the rest of the ram used for? Can I control how much ram is available?

Code: Select all

# free -m
              total        used        free      shared  buff/cache   available
Mem:             55          15          25           0          15          35
Swap:            15           4          11

I found it - correct me if I'm wrong. in the sdk root:
./.BoardConfig.mk

# Config CMA size in environment
#export RK_BOOTARGS_CMA_SIZE="66M"
export RK_BOOTARGS_CMA_SIZE="24M"

I guess that's memory reserved for the media - camera, etc. Can I set it to 0 if I don't use camera?

Hello,

You can modify RK_BOOTARGS_CMA_SIZE to a minimum value of 1 in order to free up more memory space.
