Memory range address


I have a Linux embeded device that consists
CPU, BIOS,FLASH and SDRAM.

Is there any way how to determine the memory address range for BIOS, flash and SDRAM?
(BIOS is 4Mb,Flash 64MB and SDRAM( 4 modules ) has 256MB)
Thanks

Hello,

This will give you what you want:

sudo dmidecode t | more (piping to more allows you to page using the spacebar and q to quit)

Regards.

You're welcome to the reply. I used to work with a Unix kluge for communication systems and was recently reminded of the dmidecode command. Also ran into the same thing with someone trying to recognize his RAM. There is probably a package that would allow you to install that command though.

Regards.

The easiest way will be to just look up a spec sheet for the specific board you are using. Generally that will break down the physical memory map.

I'm not sure if there's an easy way to find out from the command line.
