How to find out RAM Memory details on an embedded system?

I know from /proc/meminfo vstat, free etc, but none of the commands give you exact RAM i have.

Example, I have checked on a system where i know the RAM size of 256 Mb, but none of the above command displays 256Mb.

is that correct or am i missing something?

#8 says “Dispaly.” It should say “Display.”

Nice and neat info. I believe you meant all the mentioned kb, mb, gb are actually kibi, mebi and gibi rather than kilo, mega and giga.

In reply to Sathish.

@Sathish,

We already explained each switch used with free command in this article, I hope you gone through it each point, still I will update you that free -m is used to show the amount of memory in megabytes.
