Dragonboard 410c , only 853KB RAM


#1

How can I get the advertised 1GB RAM on the Dragonboard 410c? Did I receive a broken board?

Hi,

Don’t worry your board came with 1GB :wink:

The number you can see here is the amount of memory available for Linux
programs. Part of the memory is reserved statically for the kernel
internal/static objects (which isn’t much). Then the bulk of the missing
MBs are reserved statically for the various other cores running on the SoC
(the RPM, the secure env, DSPs, …). I don’t have a boot log with me right
now but you can get a summary of the memory usage at the very beginning of
the boot.

This is what I get:

[ 0.000000] Memory: 783492K/951296K available
(8393K kernel code, 798K rwdata , 3696K rodata, 576K init, 275K bss, 102268K reserved, 65536K cma-reserved)

Any plans to sell the board with more memory? Maybe 2GB?
