Hi,
We are trying to port Linux-2.6.13 on Custom build MPC860T, board, We are unable to see any messages on console. We got the output given below. Please help us in porting the kernel.
I am attaching the config file .
=>bootm 0x100000
## Booting image at 00100000 ...
Image Name: Linux-2.6.13

Did you do a parallel make (make -jN)? There is a problem currently
with parallel makes where it can try to use the vmlinux.gz before it's
been fully generated. Try deleting vmlinux and do a single-threaded
make and see if that fixes it.

Hi again,

Yes, lincan does. Well, it supports RTlinux and OCERA's RTlinux (GPL)
modifications, which somehow reinvent ADEOS (or is it the other way around?),
but since RTlinux is an option only for i386, and anyway almost dead right
now, you could say it doesn't support real-time extensions.
The problem of saying "Peak-CAN for SJA1000" and "OCAN for intel" is that you
can basically forget about writing portable code because they are both very
different.
Maybe you should have a look at Pavel Pisa's lincan. After trying it out you
might end up as confused as I am, because it doesn't look that bad at all,
it's almost platform independent, supports all kernels (2.2 to latest 2.6),
and supports a great amount of cards with intel and/or philips chips (yes,
both of them on one card is also an option). The driver is designed with
performance and throughput in mind, but I am not so sure about the API which
is still a little too simple (maybe that's actually good) and doesn't support
properly checking chip- or bus-status yet. Also honorable is their effort of
staying compatible with at least one other player: can4linux.
Greetings, and thanks for the comments,
Btw, how's ELDK-4 coming along?

* ARCH=powerpc kexec seems to be broken ...
From: Sven Luther @ 2005-12-28 10:48 UTC (permalink / raw)
To: linuxppc-dev
Hi, ...
I have for some time tried to build 2.6.15-rc debian kernels with
ARCH=powerpc, and never quite succeeded. Thanks to Johannes Berg
for helping investigating the issue.
The problem seems to be that my .config enables KEXEC, and SWSUSP,
which has nasty problems with ARCH=powerpc. In a 32bit config, i get :
00:03 < svenl> arch/ppc/kernel/built-in.o: In function `swsusp_arch_resume': multiple definition of `machine_shutdown'
00:03 < svenl> arch/powerpc/kernel/built-in.o: first defined here
Which seems to indicate that machine_shutdown is built twice, once in the
arch/ppc stuff and a second time in the arch/powerpc stuff.
I have a similar problem for the 64bit case, but have not yet reached the
point of the build where this happens, so i can't paste the error message
here, but it was of the same kind as above if i remember well.
Johannes said :
11:23 < johill> you enabled kexec, right?
11:24 < svenl> yeah, i did.
11:24 < svenl> is it broken for ARCH=powerpc right now ?
11:24 < johill> seems so
11:28 < johill> yeah. I don't think I can fix it, know too little about kexec
11:30 < johill> machine_shutdown should at least be moved from
arch/ppc/kernel/machine_kexec.c to some file that is ARCH=ppc specific
11:31 < svenl> johill: as i understand this, i think it is already in some
ARCH=ppc specific file, which is the cause of this trouble.
11:32 < johill> the way I interpret it is that the machine_kexec.c file is
compiled for ARCH=powerpc too since it contains the 32bit specific
implementation of kexec
11:32 < johill> but it contains a non-static machine_shutdown() function which
ARCH=powerpc already moved to some non-32bit specific file
So, it would be neat to either fix it, or at least mark the option as broken
on 64bit powerpc, or something such.
Friendly,
Sven Luther

We have looked for "free" CAN software/drivers for Linux already some
time ago, especially for embedded PowerPC processors. There are various
implementations out there, but only a few of them are "alive". A natural
choice for the SJA1000 seems to be the CAN driver from Peak Systems (see
http://www.peak-system.com/linux/index.htm). It already supports 2.6 and
seems to be well maintained. Porting it to your MPC 8xx bases hardware
should not be to much effort. The OCAN driver is for the i82527. It's a
good choice if you use that CAN controller but porting to the SJA1000
might not be straight-forward as the API uses details of the chips hardware.

AFAIK, there is no _generic_ embedded CAN driver available which even
supports real-time extensions.

Pls try 0x200000 to boot the image.
If didn't work, print the comandline
which was transfered to kernel.

* porting linux on the prpmc610 and the mvme6100

Hi
> Who knows how can I get the file?
I've got a link, but I cannot figure how to go there from the motorola webs=
ite, so maybe It's not available for everybody. I had to register (for free=
) to be able to download.
This is under GPL, so I can send this directly to you, but as they give it =
for free, I think it's better to ask them directly. (send an e-mail)
If you dont get support the standard way, come back, and I'll give you the =
patch.
On my side, I'm trying to support the board on 2.6.13. It seems that there =
is already a lot of support (for the mv64xxx at least) in the 2.6.13.
Currently I'm checking what else is supported, and what should be ported.
Have fun.

ELDK 3.1 uses binutils-2.14; the current Linux kernel was changed to
use assembler syntax which is not supported by the GNU assembler in
this version. See for example
http://ozlabs.org/pipermail/linuxppc64-dev/2005-February/003179.html
I don't understand why this was done, either. Especially as the
current Linux kernel documentation ("Documentation/Changes") still
claims that binutils 2.12 would be sufficient.
You will have to update your toolchain (i. e. use ELDK 4.0) for
working with current 2.6 kernels.
Best regards,
Wolfgang Denk

* Re: Which CAN driver to port to for PPC

Hi all,

That could of course make a difference.... eventually.
The problem I see with Ocan is that it has a very different API than all the
others. I know of at least two others, which try to be compatible (or at
least easily portable between) with each other: lincan and can4linux. I am
not sure but I think they started from the same base, and somehow agreed to
stay API-compatible.
Ocan's API on the other hand, seems to be tailored around the intel
controller, and doing little more than offering a user-space interface to the
chip, much in the same way as one is used to programming small
microcontrollers with integrated CAN periferals. I wonder how the port to
SJA1000 will turn out, since I believe it would have to emulate some
82527-specific stuff, in order to offer a compatible API.
The advantage OCan might have, is probably better control of timing, since
AFAIK, one can avoid using queues, which give additional delays if the queue
is not empty; somehting often not wanted in real-time applications.
Also one difficulty in designing a good CAN driver model, is the fact that CAN
offers up to the link-layer in hardware, and the rest is application
specific, so it is hard to do much in the driver without hampering some
possible application. I am convinced though, that there should be a
chip/card-independent API to the application-programmer, and that effort
should be done to converge into the same direction. Programmers now really
have a tough time choosing, and that is as bad as having no choice at all
IMHO.
So, wouldn't it be better to try to unite forces and at least offer similar
API's, or even better, develop a standard linux CAN framework? I guess there
is little chance something like this will ever become part of the kernel, but
right now the situation is really awful. CAN is quite popular for embedded
systems, but even embedded systems developers like to write portable code.
Regards,
P.S.: Alessandro: I have copy of "LDD1" on my desk, and I like it a lot.
Thanks!

zImage.prep built from head of Linus' tree fails to boot with the error

Dears,
I am using ELDK (2005-06-07) and linux-2.6.15-rc2-2005-12-03-2208.tar.bz2
to build the kernel. But there are some errors:
.../arch/powerpc/kernel/vdso32/gettimeofday.S: Assembler messages:
.../arch/powerpc/kernel/vdso32/gettimeofday.S:28: Error: unknown pseudo-op:

.......
Anybody knows what happened ? And is there any way to solve ?
Thank you for your help.

Hi all:
I want to port Linux to the prpmc610 system and mvme6100,does any one has
the experience for these boards?
The prpmc610 has the ppc5bug.
Also I found there is file for that named "patch-2.4.25-mcg.rm01.gz ", it
was patch for mvme6100 on the standard kernel. Who knows how can I get the
file?
Thanks all.

I need to port ocan to support SJA1000 on an ARM device, as a client
asked for it. Also, another client asked for a 2.6 port, so all of
this will happen pretty soon (2-3 weeks). I don't know if that makes
any difference.

* [PATCH] PPC44x EMAC driver: disable TX status deferral in half-duplex mode
From: Eugene Surovegin @ 2005-12-27 20:36 UTC (permalink / raw)
To: Jeff Garzik; +Cc: netdev, linuxppc-embedded
Disable TX status deferral (EMACx_MR[MWSW=001]) in half-duplex mode.
I have two reports when EMAC stops transmitting when connected to a
hub. TX ring debug printouts show complete mess when this happens,
probably hardware collision handling doesn't work quite well in this
mode.
This is relevant only for SoCs with EMAC4 core (440GX, 440SP, 440SPe).
Tested on 440GX.

* Which CAN driver to port to for PPC
From: David Jander @ 2005-12-27 16:30 UTC (permalink / raw)
To: Wolfgang Denk; +Cc: linuxppc-embedded
Hi,
We have developed CAN hardware based on the Philips SJA1000 controller hooked
to a MPC8xx based processor board. Now we want to write driver support for
it. My first try was lincan-0.3.1, which seemed quite well written at first
glance. Porting was easy too, and the driver works fine on our board with the
latest kernel (2.6.14).
But.... this driver lacks a proper way of checking the status of the CAN
controller from userspace :-( Not that nice after all!
Then I see on the DENX website, mention of Rubini's OCAN (mostly useless to
us), and Peak's PCAN drivers (there is a port for MPC5200 on DENX's site). No
word about lincan, though.
The reason I suppose is, someone already figured out that lincan is not a good
choice for whatever reason (status reportability ??), right?
Before beginning to re-invent wheels and re-discover known problems in certain
CAN driver architectures, could someone please point me to the right place to
start looking for answers (if that place exists) or just give the answer,
opinion or experience with one of PeakCAN, lincan, can4linux, etc...?
I am again puzzeled about which way to go.
Thanks for any advice,

I want port Linux system to the MVME6100, I found moto has this kind of
patch for the MOTO SBC, just like patch-2.6.6-mcg.rm01.gz file.
Any know how and where can I download it?
Thank you very much.

If you are running in the U-Boot environment, then you can use
standard C programs; read about "standalone applications" - but this
is off topic here; please read the docs and post any remaining
questions on the u-boot-users mailing list.
Once you started the Linux kernel, then all of U-Boot is gone and
dead and there is no way to call any U-Boot code any more - except by
resetting the board.

I don't know of public example code but in general it is pretty easy.
Just set up the EBC registers to map your device into some unused
address space, and then use ioremap() and friends to access the bus.

* Can I use the system call provided by uboot in an assembly language program as in ppcbug?
From: Zhang Xin-W22390 @ 2005-12-26 12:43 UTC (permalink / raw)
To: linuxppc-embedded
[-- Attachment #1: Type: text/plain, Size: 494 bytes --]
Hello,
I want to call some system calls to do input/ouput in assembly language
program, and does uboot provide such syscall? As in PPCBUG, I can
program the following code:
li r10,0x0022
sc
to do an output to console.
I know I can program a standalone application using printf() to achieve
this function, as illustrated by the example uboot provides. Instead, I
want to use assembly language.
Thanks and Regards.

Our board is PQ2FADS_ZU,and we bought a BDI2000 to debug it.
There is a LH28F016SC flash in the PQ2FADS_ZU board.
I tested the default .cfg (for 8260ads) to driver LH28F016SC flash,but it didn't work.
How to modify the .cfg file? thanks.
