lx2160ardb DRAM is lost about 2G

tsungmin_wang · ‎10-30-2020

Hi,

I just got a lx2160ardb_rev2 board, and I found that the memory size is lost a lot.

There are two 16G DRAM on lx2160ardb_rev2, according to this meminfo, there is only 29.3G memory.

Why does it lost so much memory?

Hi,

I update the pos several years later but I have the same question and what I understand from your answer is that you explain a loss of 66+2+512MB = 580MB but not all the 2Gb.

From boot start logs we can see that there is a Reserved area of 2702860K (see bellow). Can you explain why (and where) the kernel reserve such amount of RAM and if we can reduce it?

Hi,

Thanks for your reply.

So, does this mean that I can't use SDRAM with memory size lower than 2G?

I found 15.6.1.1 Supported DDR SDRAM Organizations from LX2160ARM.

It shows that the board supports 1G byte SDRAM (or it must use two Banks?).

And there is a memory map for 2G (LX2160A System Memory Map)

If I use SDRAM that memory size is under 2G, does it still reserve about 2G memory size for Linux?

lx2160ardb DRAM is lost about 2G
