[U-Boot-Users] PCI, Ethernet, IXDP425

[Ara Avanesyan]

Hi all,

I've just got my ixdp425 evaluation board and tried u-boot on it.

I have a PCI Ethernet card on the board. I need to connect to the network 
from u-boot via this device.

Are there any ways to do so? What I will have to do to enable this support? 
Or at least are there ANY PCI Ethernet drivers in u-boot?

Thanks for your help,
Ara

Just do it.

How about checking the code before posting?

Yes, there are.

Thanks for so helpful and informative reply.

configs/ixdp425.h, line 59:
#define CONFIG_COMMANDS         (CONFIG_CMD_DFL & ~CFG_CMD_NET)

So how about checking the code before posting?;-)

Thanks,
Ara

Ara,

If you see the driver for your PCI Ethernet card on the drivers
directory, then you'll be fine.  However, you may need to write your
own driver if it does not exist.  So check on the drivers directory
first and then, if it exists, write the appropriate CFG parameter on
the configs/ixdp425.h file.  try removing the ~CFG_CMD_NET, and other
parameters that the driver might require.

Regards,
Rodel

P.S. Anyone working on ethernet MAC's with MII-only interfaces??? I'm
actually lost... Please help.

[Ara Avanesyan]

Thanks Rodel,

I think we'll switch to one supported by u-boot right now, as poritng will 
take a long time.
Ok, I'm going to play with u-boot's net paramters.

Thanks,
Ara

I have tried to approach the ethernet driver development for IXP425 NPE, but
unfortunately there are some problems with the Intel library and the APIs
that are not well described.
The source code seems to be not completely available as well.

Actually we have stopped the driver development on u-boot by accepting only
to use the NPE with linux (which still requires a big part of library to be
resident to work properly), but we are ready to evaluate any possible
cooperation to support this development.

Gianfranco

So what? The "CONFIG_" part in this define is  intended  to  indicate
that  this is a user configurable setting - one user does not need or
want network support, another may want it.

What exactly are you complaining  about?  That  you  don't  find  the
system pre-configured to your specifc wishes?

The ixdp425 port does not _include_ PCI support; that does not mean PCI
is not supported.

You still haven't mentioned which one...

You obviously haven't done your homework (i.e. read the README),
otherwise you would have known that Wolfgang is the project leader.

You sounded a bit aggressive to me, and you are wrong again: The  IXP
port does support PCI:

Sorry for being so rude. I shouldn't write like that, i just got somewhat 
uncomfortable when I asked a help for doing something and you said "just do 
it".

omg, the PCI support was added like three days ago, I'm now feeling so 
lucky.
(I spent all my day reinventing the wheel). I'm now going to try it out.
I really hope it will work.

Hey, thanks!

[U-Boot-Users] [PATCH] fix the ARM memory layout

[Anders Larsen]

Hi,

here's a fresh version of my rather intrusive patch from the 17.th sept.
to rearrange the ARM memory layout to bring it in line with the README.

This has the positive side-effect of actually allow U-Boot to run on
PXA- and IXP-based targets; the current implementation sets up the heap
using bogus addresses causing u-boot to crash (this even applies to the
recently added board "ixdp425").

This patch doesn't go all the way, though, since doing away with the
board-specific setting of TEXT_BASE would require the code to be
position-independent, which at least the cpu initialization code in
cpu/*/start.S is _not_.

CHANGELOG:
   Bring the ARM memory layout in line with the documentation.

Cheers
 Anders

I don't disagree that memory layout for ARM is broken. But, I've never seen a 
crash on any of my Xscale boards, including a couple of new ones based on 
ixdp425 and cradle.

Hi Kyle,

Do you by any chance happen to have RAM at and around address
0x0badc0de ? Otherwise I don't see how PXA/IXP could possible work,
for the reasons Richard already gave.
(see also http://www.catb.org/~esr/jargon/html/S/schroedinbug.html ;-)

(BTW, I recognize you've contributed significantly to the PXA
implementation I'm relying on and I'd like to thank you for that).

Yeh, I don't doubt there is a problem. I guess I need to take a closer look 
and see why it works. But finding the time to work on something that actually 
already works is difficult...(got plenty of stuff that doesn't work to keep 
me busy).

> (BTW, I recognize you've contributed significantly to the PXA

You're welcome. But all I did was put the framework in place so that you and 
Richard and others can make it work correctly ;)

I think the mystery is solved. I just updated my latest pxa to 1.0.0. It was 
based on 0.2.3 and the ixp port was based on 0.4.0. Early versions of the 
code, while not perfect, did run. Definitely a problem with the later stuff 
without proper patches (thanks for the patches).

Hi Wolfgang,

what's needed to make the patch worthy of inclusion?
I know the patch doesn't go all the way you want, but IMHO we need
several steps for that in order not to wreak too much havoc.

You are right, and I am perfectly willing to add  this,  but  at  the
moment  I'm caught in some other activities. I hope to find some more
time for U-Boot next week.

Best regards,

Sorry, I'm working through my backlog sequentuially,  and  I  already
added  the  other  patch.  Can  you please check your current version
against current top-of-tree in CVS and provide a new diff?

Thanks.

Best regards,

Hi Wolfgang,

sure, only I can't say when I'll be able to do it, since
cvs.sourceforge.net is currently rejecting connections  :-(

Hi Wolfgang,

the attached patch (against CVS 2004-01-08) fixes the rest of the ARM
stuff I had in the pipe.

In particular, the abort-stack is now set up in the correct RAM area
(which I had neglected in my previous patches), and the BSS is zeroed
out as it should be (which most previous ARM implementations had
neglected).

Furthermore, the magic variables 'armboot_end' and 'armboot_end_data'
of the linker scripts are replaced by '__bss_start' and '_end', resp.,
which is a further step to eliminate unnecessary differences between
the implementation of the CPU architectures.

Compilation tested with MAKEALL arm, functionality only tested on my
PXA-based board.

CHANGELOG:
   Fix the ARM memory layout.

Cheers
 Anders

Thanks a lot, added.

I tested it on the SMDK2400 and TRAB boards with several memory  con-
figurations. Workes fine. Thanks a lot!!

In theory, there is no difference between  theory  and  practice.  In
practice, however, there is.
