For arch/ppc? Not that I'm aware of. But that wasn't particularly my
point. The email says "This patch updates the ppc and powerpc
architectures..." when it doesn't.
I think most agree that arch/ppc needs to die via a complete migration
to arch/powerpc. But patches shouldn't claim to do something they
don't :).

Yeah, I was just thinking that there are programs relying on that and if
they run in the 32-bit compat mode they might rightfully do so... Dunno.

I just booted up my Pegasos and tried the offb driver for display and was
rather disappointed. It just displays 4 lines about HID0 and stuff and then
waits around.
Is this all there is? Is there nothing more? Can't I get a scrolling kernel
output, and a penguin logo or am I missing the point? :)

Maybe someone can help if you give more details, e.g. the kernel
version, and exactly what messages are displayed before it hangs.

Nah. It isn't a valid assumption; just as it isn't valid to assume that
your stack will _always_ be at about 0xbfffffff.

Ok.
Just curious though: Why does READ_IMPLIES_EXEC exist at all then?

I've tried what you've mentioned below, i.e removing the /sbin/init and

standalone shell. I am having a Linux 2.4 Kernel (Montavista 3.1)

For debugging or single user purposes you do not need to run init or
have an inittab.
There have been several sugestions that there may be a hardware
problem - there are a number that are possible.
I was stalled here for some time because my UartDriver was
accidentally using the physical IO address instead of the virtual one
and I had created a temporary phys=3Dvirtual entry in the tbl that =
was
conveniently getting blow away just here.
You can try to isolate your problem by changing your boot ramdisk
(inramfs or initrd)
Eliminate or rename /init /sbin/init /linuxrc and any of the other
permutations that linux tries to execute in init/main.c they are all
listed very near where you stopped.
make sure you have /bin/sh
reboot on that ramdisk if you have an "init" related problem then
you should get a standalone shell.
If you have a hardware problem you will likely still stop at the
same place.

Makes sense. The patch on top of the latest -mm is below if you want to push
it. It has not been boot tested as building with the latest -mm is broken
at the moment for older powerpcs because of the git-powerpc.patch patch .
That patch assumes that mm_context_t is a struct with a vdso_base which is
not always the case (it's an unsigned long in include/asm-ppc/mmu.h).

* No ttyS device at I/O port 0xfe004500 for console
From: Alex Zeffertt @ 2006-06-13 16:48 UTC (permalink / raw)
To: linuxppc-embedded
Hi list,
I'm trying to boot a linux-2.6.11 kernel on a MPC83xx based board. Through
some experimentation I have found I need "console=uart,io,0xfe004500"
in the kernel command line in order to get any output over the serial
port.
Half way through initialisation the kernel appears to swap from its "early"
8250 serial driver to a "full" 8250 serial driver. At this point it prints
"No ttyS device at I/O port 0xfe004500 for console" and there is no
further output.
Does anyone have any idea what I may be doing wrong?
BTW, here's the output that I do get.

I'm using the SMC2 serial device of MPC880 without using hardware handshake. I
use only tx and rx at a speed of 9600. Could it work? The driver I use is

Alex, where did you get this 2.6.11 kernel? The public tree didn't
have support for 83xx in 2.6.11. I'd suggest looking at using
something newer like 2.6.16 and see if you have the same issue.

I suspect he got from the same place I did, freescales LTIB dev. env.
which has been patched to support 832x. I am having the same problem as he
has, any info on what the problem might be would be great.
Also, if anyone has any info on when these patches will be sent upstream, I
sure would like to hear about it.

* Re: help with inittab
From: David H. Lynch Jr. @ 2006-06-13 21:07 UTC (permalink / raw)
To: Anantharaman Chetan-W16155; +Cc: linuxppc-embedded
In-Reply-To: <EDF27F298D4B03498AE0C249A941DFF803D70E@de01exm68.ds.mot.com>
My specific problem turned out to be that the serial driver I had
written was still using the physical IO address that I had temporarily
mapped (virtual=physical) during very early boot, and when that
temporary mapping went away I instantly became deaf and dump and it just
happend to go away while starting init.
But for a long time I though I had other problems, so things I tried
included:
Writing a simple "hello world" program and running that from
where the kernel starts init.
I think where the kernel starts init is the first place that
Linux actually starts making use of virtual memory.
I beleive that the way the kernel loads a program involves actually
forcing pagefaults, so alot of things can work, but if paging is not
working perfectly
you will not be able to start another process.
Another thing you should watch out for is that there are two
places Linux looks to start an "init" process.
The first uses whatever might be specified as a commandline
argument (or in your .config, or hardcoded in some BSP's)
If that fails then it starts through a list of potential init
processes until one starts.
I recently had a problem where I wanted to start "/bin/sh" as my
init so I commented out everything else, but left the command line
argument option in and still did not get /bin/sh because it was picking
up the argument from elsewhere.

* Init dies with unhandled signal 4
From: David H. Lynch Jr. @ 2006-06-13 21:16 UTC (permalink / raw)

In-Reply-To: <528646bc0606121303p35d4955dn60b82dc5fa6c9566@mail.gmail.com>
I am trying to move my Pico E-12 port from 2.6.15 to the current 2.6
from Linus's git tree.
Most everything moved fine, but now "/init" dies with an unhandled
signal 4 which I beleive is an invalid CPU instruction.
I do not have this with 2.6.15 and Linus's tree is obviously more
bleeding edge.
I am just asking whether I should be trying to track down a problem with
my code or if this might be a problem in the git tree.

* RE: MPC5200B SPI PSC3 Problem
From: Trueskew @ 2006-06-13 21:11 UTC (permalink / raw)
To: linuxppc-embedded
Ok, I'm slightly less confused, and since I may have caused confusion I'll
clarify a little here. Sorry if some of you knew this already.
The MPC5200B has an SPI interface described in Chapter 17 of the MPC5200B
Users Guide. It uses either lines PSC3_6 - PSC3_9, or some of the Timer
pins. The MPC5200B also has an SPI available through the PSCs that use the
codec lines (PSC3_0 - PSC3_3). Depending on what rev of the user's guide
you have, there's a table in Chapter 15 that suggests you can set up PSC3
for Codec and SPI. Unfortunately, the SPI they're talking about is the
8-bit SPI, not the PSC3 SPI.
That was the basic source for my confusion. Hints here and in other places
and some parts of the manual suggested, but it was the scope that really
drove that home for me. I won't elaborate anymore here since for all I know
I'm the only person who just figured that out, but if anyone is struggling
like I just did and has any questions, I'm not a guru but I'll try to help.
Good luck.

Alex, can you post your complete u-boot env(printenv). I am trying to do
the same as you but I havn't gotten any output yet. I managed to wipe my

Hi Joakim,
Same here -- go into arch/ppc/platforms/83xx and edit file mpc83xx_sys.c.
If you are using the 8323e cpu, then you need to make sure that file has
code to support the 8323E. Mine didn't, so I got no platform devices
initialized (no serial port, no Eth devs). I added a block of code to support
the 8323E (set mask to 0xffff0000 and "value" to 0x80620000, then the
device list for the 8323E). Use existing code there as a guide, it was not
difficult once I figured out that this was the problem.
If you are using a newer LTIB release than me, perhaps yours is fixed.
The one I have is from 3/15/06.
Anyway, this works fine for me and addresses the problem of the platform
devs not getting initialized.
Chuck

Hi
Do I understand it right that in the stock 2.6.17-rc... kernels
suspend-to-RAM is not available to any embedded ppc processors / boards?
Only for powermac? Is it for a reason (which one?) or just nobody has done
/ submitted to mainline this?

[-- Attachment #1: Type: text/plain, Size: 10999 bytes --]
Hi all,
I have been trying for days now to get my usb flashdrive to work on my
Motorola MPC5200 (IceCube) board running on the 2.4.20 linux kernel. I have
followed the instruction in this Flash Memory HOWTO article
(http://www.tldp.org/HOWTO/Flash-Memory-HOWTO/index.html
<http://www.tldp.org/HOWTO/Flash-Memory-HOWTO/index.html> ), but I have had
no success.
When I mount the usbfs filesystem (mount -t usbfs none /proc/bus/usb/) the
following 3 items are created in the /proc/bus/usb/ directory:
dr-xr-xr-x 1 root root 0 Jan 1 00:12 001

In the this Flash Memory-HOWTO it is mentioned that the usb-storage-x
directory will be created in the /proc/scsi/ directory, but I do not see it
on my system. Also the contents of /proc/scsi/scsi are "Attached devices:
none".
