[U-Boot-Users] generating a u-boot Linux image for PXA255

[Greg Lindberg]

Does anybody have a script that they'd be willing to share for running
mkimage on a Linux kernel for an Intel PXA255.  I'm just getting started
with u-boot and I'm not sure of all of the parameters for mkimage for the
PXA255.  Any help would be appreciated.

What's wrong with the scripts included with trhe U-Boot source  tree?
Why don't you want to use those?

Argh.. sorry. I've been completely off  track.  I  thought  you  were
asking foir a linker script. Sorry...

You can just "ask" mkimage:

-> mkimage -?
Usage: mkimage -l image
          -l ==> list image header information
       mkimage -A arch -O os -T type -C comp -a addr -e ep -n name -d data_file[:data_file...] image
          -A ==> set architecture to 'arch'
          -O ==> set operating system to 'os'
          -T ==> set image type to 'type'
          -C ==> set compression type 'comp'
          -a ==> set load address to 'addr' (hex)
          -e ==> set entry point to 'ep' (hex)
          -n ==> set image name to 'name'
          -d ==> use image data from 'datafile'
          -x ==> set XIP (execute in place)
-> mkimage -A ?

Invalid CPU Type - valid names are: alpha, arm, x86, ia64, m68k, microblaze, mips, mips64, ppc, s390, sh, sparc, sparc64
...
-> mkimage -T ?

Invalid Image Type - valid names are: filesystem, firmware, kernel, multi, ramdisk, script, standalone
...

etc.

I found a number of boards using the PXA255 processor, I've gotten u-boot up
a running on an InHand FingerTip3 board, that was not the problem.

What I asked for was scripts for running mkimage against a kernel for the
PXA255, I wasn't sure about all of the switches and thought that someone
might already have a script that might save me (and others) some time
getting the switches right.  I still haven't gotten any information about
running mkimage for an PXA255 target, although I think that I have figured
out how the switches should be set.  It would be nice if the section in the
readme that mentions mkimage listed the values of the different switches
that are supported so that it wasn't necessary to go paw through the source
code to find them.

Please learn to quote properly. Don't top-post/full-quote.

What is so difficult about finding boards with PXA255?

Trivial approach:

	-> grep PXA255 include/configs/*
	include/configs/pleb2.h:#define CONFIG_PXA250           1       /* This is an PXA255 CPU    */
	include/configs/xaeniax.h:#define CONFIG_PXA250         1       /* This is an PXA255 CPU    */

There you go...
