Minimal uImage (compressed Linux kerne)l size for PPC 8270 processor

Started by Unknown July 5, 2007
Hi,

I am poring from Linux 2.4 to Linux 2.6. My board is based on PPC 8270
processor of  FreeScale (former Motorola).

The uImage (compressed Linux kernel)  size on Linux version 2.4 was ~
720
Kbytes.  What size should I expect on Linux 2.6  ?

What is the typical/minimal uImage  Linux kernel size , assuming that
I am
using TCP/IP, UART, etc.

The drivers  that we added are not so  big in size, so loading them
dynamically will not reduce largely the size of Linux uBoot Image.


Thanks,

Martin Roth

I can't speak for typical/minimal, but I have a uImage for an 8347 that is 1.2MB. This is a rather "full-featured" kernel. Hope that helps. -- Michael N. Moran (h) 770 516 7918 5009 Old Field Ct.
