MPC880 and ELDK

MPC880 and ELDK

[Sanjeev R]

Hi ,
I need some  details  , if I have to work on MPC880 and linux.
There are some questions to get clarified.

 Does  ELDK support  MPC880 arch? (linux distro in it)
If yes , can i have some details on that?
If ELDK doesnt is there any other distro i can go for..?

 Since Uboot supports MPC885 i presume it has to support MPC880, coz except
 for the extra security module and the SCC they dont differ a lot.

 Thanks in advance
 Sanjeev

The MPC880 is just  another  member  of  the  MPC8xx  family.  It  is
supported by the ppc_8xx packages in the ELDK.

See http://www.denx.de/ELDK.html

I think your question is wrong. You don't need a new or special Linux
distribution for each new processor. What you need is  processor  and
board  support in U-Boot and the Linux kernel - but this is obviously
board dependent.

Tey are just like all the other 8xx processors.

Hi Wolfgang,

I'm trying to build Qtopia-free 1.7 using ELDK 3.0 and I noticed it does
not contain a jpeg library which is required by Qtopia/QPE.  Do you know
anyone who've already built that for the ELDK?  Otherwise I'll have to
build it myself.

Try it out; it should be pretty straightforward.

Is there an idiot's guide to run the configure script to generate a
makefile that uses a cross-compiler instead of the native gcc.  I like to
build it from my ix86 box.  I'm getting a headache from googling...

This seems to do the trick.

CC=ppc-linux-gcc ./configure --disable-shared ppc-linux
--prefix=/home/davidho/usr/local
