kernel customization
 

What could be the minimum size (approx) of the kernel(2.6.32)image generated by configuring using menuconfig ?.The only purpose of my kernel is to run an application which communicates with a server using TCP/IP and loads another kernel using kexec.Has any one created such a small kernel?

Hi, welcome to LQ!

No disk, no other I/O but TCP/IP? On what medium? What platform?
How much RAM? ...


Not enough info to make any valid guesses.

Hi ,
Thanks for your reply.Sorry I didn't mentioned much details.Well there's SATA/HDD from which the bootloader loads my kernel and I'm running on an x86 platform with 256MB RAM(It's an embedded system).

Hello newbie2020 and welcome to LQ,

I'm no expert in embedded systems. For a normal Linux System with not too much hardware the kernel can be downsized to about less than 1,5 MB.
For embedded system using google I found this (as an example): http://elinux.org/System_Size#Runtime_size_of_kernel and http://focus.ti.com/lit/an/spraah2a/spraah2a.pdf
