Exception 200 is "Machine Check". If you are getting this on linux
start up it is usually due to a double bus fault which is usually due to
a memory map problem. Silent boot failures are also often caused by
memory map problems... switching from physical memory mapping to virtual
(turning on the MMU).

Hi Rick,
I saw on linuxppc-embedded at ozlabs.org that you are trying to port (or =
better you did) monta vista linux to Avnet's V4FX Mini-Module. I will =
try to deal with the same thing. My design is basically the same: all =
features of MM incorporated in CoreConnect style architecture. I also =
tried with Multi Port Memory Controller (MPMC2) and ported (memory =
works, but for LAN I still need phy datasheet) the Gigabit System =
Reference Design (GSRD2) to Mini-Module.
By using the MPMC2 memory core you can connect PPC directly to memory =
using two PLBs (data and instruction separated). This way you might =
solve the CPU cache errata. The problem with MPMC2 is that it consumes A =
LOT of BRAM and logic. I tried to build a full featured system, but =
V4FX12 lacks logic for the purpose.
Is there a way that you can help me with running MV linux on my system?
Cheers,
Ales Gorkic

Hi,
FOA - asking one list is enough!
For 2.4 kernel, you've answered your question by yourself - (un)check the kernelconfig for xmon in
kernel hacking menu - this should do the trick,
For 2.6 kernel: what about your bootargs settings? also check the console settings of your
kernel config.

Hi,
Yesterday I tried to compile kernel with linux-2.4.27 and linux-2.6.17 for PowerPC405EP board. Both of the kernel images were created successfully, but when I tested them in ram from u-boot with NFS used. Both of the images could not booted from ram. The two kernel .config files are attached.
For the 2.4.27 kernel, after running bootm in u-boot and "Uncompressing Kernel Image ... OK" printed on the screen. There are
"vector: 200 at pc = c0197d4c, lr = c0197d40
msr = 1030, sp = c0181fb0 [c0181f00]
current = c0180020, pid = 0, comm = swapper
mon>".
It seemd the booting process had entered a monitor, but I didn't know what it was.
For the 2.6.17 kernel, after running bootm in u-boot, the booting process stops at "Uncompressing Kernel Image ... OK". No other output after this sentence on the screen.
Would you like to give some advice about this? Thanks a lot.

* FW: PCI Related issue please give us some solution
From: Yogesh Kumar M @ 2006-07-12 11:08 UTC (permalink / raw)
To: linuxppc-embedded
[-- Attachment #1: Type: text/plain, Size: 2091 bytes --]
Hi All,
This is yogesh,we have a custom made board with
1)MPC5200B(with host bridge support)
2)PCI2PCI Bridge device from texas instruments TI2250 (PCI2250PCM)
3)DM642 dsp based processor
and other I/O devices like serial port,HDD interface,ethernet etc
we have successfully ported U-BOOT 1.1.3 and linux-2.4.25 where all
resources are working fine we where able to commnuciate form HOST to TARGET
and from TARGET to HOST using PCI2PCI Bridge where MPC5200B is acting as
HOST and DM642 is TARGET
Now we have migrate from 2.4.25 to 2.6.11.7 where booting is happining but
we have problem in PCI where we are not able to do host to target or target
to host commnuciation we have added some fixup code for PCI but found
nothing useful
can you please tell what could be wrong and what is the major difference
2.4.25 to 2.6.11.7 pertaning to PCI
find the attachment to the log files of both 2.4.25 and 2.6.11.7
please help out since we are struck with this problem for a long time.
when we tried 2.6.17.3 kernel source from kernel.org
we got the following log the kernel hangs after uncompressing
(LINUX-2.6.17.3)

I was (naively) thinking that if I could access the legacy VGA register
set, I could set the graphic card to text mode and use the graphic
screen as a alphanumeric console, until linux soft boots the graphic
card . Do you think this is doable? I haven't been able to locate that
VGA register set yet.
Thanks,.

Yes, that is right! When I say... I have tested - "it really means I
have tested". So what's the problem? It works for me but not you? The
obvious difference: mine is a ML300 configuration and yours ML403.
There were some files which unknowing were made dependant on ML300
target. I have now made them compile for both targets. It should work
fine for you now (Hopefully!). Download the updated patch from the same
location.
http://www.cs.york.ac.uk/rtslab/demos/amos/xupv2pro/patches/linuxppc-2.6.17_sysace.patch
Since I don't have ML403 board, theres no way I can test this patch on
it. I rely on you in doing this... and thanks for letting me know the
issues.
WARNING: There might be more issues. :-)
Please DONOT hesitate to raise any issues with the driver. I am more
than happy to fix them.

To: linuxppc-embedded
[-- Attachment #1: Type: text/plain, Size: 915 bytes --]
Hi,
I failed to setup RMII ethernet interface of the UBoot on my custom board -- PPC440GP,
It always tell me "time out", and the wrong ethernet speed, why?
I defined the MII and RMII macro in my config header, and still does not work.
(Anyway, I success to setup a MII ethernet interface on the PPC405GP,should I change the RMII interface to MII on the hardware level?)
logs:
u-boot => tftp 0x100000 tmp.img
miiphy_register: non unique device name 'ppc_4xx_eth0'
Waiting for PHY auto negotiation to complete..... TIMEOUT !
done
ENET Speed is 10 Mbps - HALF duplex connection

Hi Claus.Gindhart
Thanks for patch.
I have tried the same and could do it.
I have modified the lib/configure file manually and gave the following
command
#make CC=powerpc-linux-gcc
I could get the lspci, setpci commands.
Need to test this with my target board. Let you know after testing.
But when i tried with applying patch directly.. i got the following error:
[root@localhost pciutils-2.1.11]# patch -p1 < patch-pciutils
patching file lib/configure
Hunk #1 FAILED at 12.
1 out of 1 hunk FAILED -- saving rejects to file lib/configure.rej
[root@localhost pciutils-2.1.11]#
I have just copy pasted the patch from my mail and tried.
Thanks & Regards

* [PATCH 3/3] Make the hvc_console output buffer size settable

So the iSeries console will be faster since it can send up to 200 bytes at
a time to the Hypervisor. This only affects the tty part of the console,
the console writes are still in 16 byte lots.

Char major was never used for iSeries consoles in the mainline kernel.
It has been used for the pSeries virtual and RTAS consoles and will be
used for the new iSeries console.

* [PATCH 1/3] A new iSeries console
From: Stephen Rothwell @ 2006-07-12 7:06 UTC (permalink / raw)
To: paulus; +Cc: ppc-dev
This driver uses the hvc_console.c infrastructure that is used by the
pSeries virtual and RTAS consoles. This will allow us to make viocons.c
obsolete and is another step along the way to a combined kernel (as
viocons could not coexist with CONFIG_VT).

This will also eventaully lead to code savings as viocons.c is 1162 lines
long. The down side is that the name of the console tty device changes
from /dev/tty0 to /dev/hvc0.

* Problem in PCI resource allocation with MPC8245
From: Kenny @ 2006-07-12 5:36 UTC (permalink / raw)
To: linuxppc-embedded
[-- Attachment #1: Type: text/plain, Size: 6628 bytes --]
Hi,
I have a Freescale MPC8245 machine running Montavista Linux (kernel 2.4.20).
There are two devices connected to the PCI bus:
a USB host controller (VIA VT6212L) and a single-chip network switch (Broadcom BCM5650).
Now BCM5650 is working but VT6212L is not.
I tried to modify the PCI code but met some problems.
Here are the PCI information and boot message:
Bus 0, device 0, devfn 0 (id 1057-0006, headertype 0x00)
region 0: mask 0x00000008, now at 0x00000000

It seems no problem with the allocated resource regions for VT6212L, but I got "Timeout" message printed by USB driver.
So, I modify the function "mpc10x_bridge_set_resources" in "arch/ppc/kernel/mpc10x_common.c":
case MPC10X_MEM_MAP_B:
pci_init_resource(&hose->io_resource,
0x00000000,
0xffff, /* original value: 0x00bfffff, */
IORESOURCE_IO,
"PCI host bridge");
--
and the defination of MPC10X_MAPB_PCI_IO_END in "include/asm/mpc10x.h":
#define MPC10X_MAPB_PCI_IO_END (0x00010000 - 1) /* original value: (0x00c00000 - 1) */
--
After modification, the USB 1.x driver (UHCI) is working, and EHCI is still not working.
BUT I don't know why the UHCI works if I do the above modification?
The PCI information after modification is shown below:
Bus 0, device 17, function 0:
Class 0c03: PCI device 1106:3038 (rev 97).
IRQ 1.

I have really no idea about this problem because I'm pretty new to PowerPC and PCI architecture :'(
(So I think my modification may not reasonable)
Can anyone help me solve this problem ?
Any pointers and help would be greatly appreciated.
Thank you!

* [PATCH 16/16] [powerpc] Make get_property() return a const void *
From: Jeremy Kerr @ 2006-07-12 5:42 UTC (permalink / raw)
To: linuxppc-dev
Previous changes have treated the return values of get_property as
const, so now we can make the actual change to get_property(). There
shouldn't be a need to cast the return values anymore.
We will now get compiler warnings when property values are assigned to
a non-const variable.
If properties need to be updated, there's still the of_find_property
function.
Built for cell_defconfig, chrp32_defconfig, g5_defconfig,
iseries_defconfig, maple_defconfig, pmac32_defconfig, ppc64_defconfig
and pseries_defconfig.

* [PATCH 09/16] [powerpc, video & agp] Constify & voidify get_property()
From: Jeremy Kerr @ 2006-07-12 5:40 UTC (permalink / raw)
To: linuxppc-dev
Now that get_property() returns a void *, there's no need to cast its
return value. Also, treat the return value as const, so we can
constify get_property later.
powerpc-specific video & agp driver changes.
