Hello all,
I am trying to cross compile the kernel for ARM922T based board. I
have downloaded the kernel source. The kernel compilation steps given
on arm-linux ask me to:

For 2.6 kernels, the process is similar. Use <machinename>_defconfig to
select the machine, eg:
bash$ make netwinder_defconfig

there is no config file in my linux folder. I guess it is specific to
the machine for which I am compiling my kernel How should I get it?

Thanks and Regards,
Noor

Hello,

I'm looking for an application and hopefully a device that I could use
to run 2 instances of an embedded linux OS on a cellular phone. The
phone would ideally boot into the virtual machine monitor (VMM) and
then load the 2 seperate operation systems both as virtual machines.
The architecture is unimportant as long as there is currently a mobile
phone supporting it and a VMM supporting it.

If anyone has any information, references, or resources that they could
point me to, I would really appreciate it. Or if anyone knows of any
emulators for developing (linux or windows x86) I would also appreciate
it.

Thanks

hi all:
when i selected configuration entries in MTD subsystem in the process
of kernel compiling, in the "RAM/ROM/Flash chip driver" subentry, if
only I select "Support for absent chips in bus mapping" subsubentry, I
just get result such as follows:
--------------------------------------------------
sh-2.04# cat /proc/mtd
dev: size erasesize name
mtd0: 01000000 00001000 "Physically mapped flash"
--------------------------------------------------
This make me think about the flash devices had recongnized.
however:
---------------------------------------------------
sh-2.04# cat /dev/mtd0
cat: /dev/mtd0: No such device
---------------------------------------------------
It indicates that kernel has no such device. I read help of "Support
for absent chips in bus mapping" in details:
-----------------------------------------------------------
CONFIG_MTD_ABSENT:
This option enables support for a dummy probing driver used to
allocated placeholder MTD devices on systems that have socketed
or removable media. Use of this driver as a fallback chip probe
preserves the expected registration order of MTD device nodes on
the system regardless of media presence. Device nodes created
with this driver will return -ENODEV upon access.
-----------------------------------------------------------
This means regardless flash devices exist, they will always be
registered and get own device nodes, but if you want to have access to
them, which will prompt: no such device.

my flash is spansion s29GL064M, the two flashes both linked to CS1#, I
have compiled kernel many times and try many configuration entry in MTD
subsystem, but all of those always told me "Found no Physically mapped
flash device at location zero" except when I use the above
configuration --- but that's useless.
----------------------------------------------------
My typical configuration in MTD subsystem is follows:

Memory Techonology Device(MTD) support
MTD partiotioning support
Redboot partitions table parsing
Direct char device access to MTD devices
Caching block device access to MTD devices
RAM/ROM/Flash chip drivers->Detect flash chips by Common Flash
Interface(CFI) probe
RAM/ROM/Flash chip drivers->Detect non-CFI AMD/JEDEC-compatiable flash
chips
RAM/ROM/Flash chip drivers->Support for AMD/Fujitsu flash chips
Mapping drivers for chip access->CFI flash device mapping driver

OR

all of entries in "RAM/ROM/Flash chip drivers" was selected.

but the result was always:
physmap flash device 1000000 at 4000000
genprobe_new_chip called with unsupported buswidth 2
JEDEC: Found no Physically mapped flash device at location zero
priv->size is zero
genprobe_new_chip called with unsupported buswidth 2
CFI: Found no Physically mapped flash device at location zero
Physically mapped flash: Probing for AMD compatible flash...
Physically mapped flash: Found no AMD compatible device at location
zero

-----------------------------------------------------------------
In both cases I can't find my flash devices. What's wrong with them or
kernel?
Hope you can throw light on this.

Topic Replies: 1

Hi, I'm trying to get a 2.4.18 kernel started from U-boot 1.1.4 on a
Freescale PPC MPC8245 processor.

The U-boot code is configured for our costume board and is running
fine. We use top boot and U-boot is in flash, which is at 0xFE000000.
IMMR is at 0xF0000000. The kernel is loaded via tftp into SDRAM at
0x00500000. All of this is working fine.

When the kernel is called from common/cmd_bootm.c I get an 'Alignment
exception', and the board resets.

Why does this cause an 'Alignment exception'?

Any help is appreciated.

Best regards

Hi,

I'm trying to work with the framebuffer, but I'm stuck on basics and
I'm totaly new to the framebuffer stuff, and embedded . I've tried to
compile a simple program that should just paint a square on the screen
(http://doc.trolltech.com/4.2/qtopiacore-testingframebuffer.html). My
problem is, that is not painting a square on the screen, instead it
paints a lot of noncence all over the screen as if something is terribly
wrong with the framebuffer. I'm totally new to this framebuffer stuff,
so I don't know where to look to resolve this problem.
My Linux Embedded is on a x86 architectur and lspci -vv is listed
below. Using make menuconfig I see that Device drivers --> Graphics
support -->
<M> VGA 16-color graphics support

and

in my grub.conf, I've tried lots and lots of different things, I've
ended upp with:
kernel /boot/vmlinuz root=/dev/hda3 video=sisfb:mode:1024x768x32

The output from the test program (except drawing lots of junk on screen) is:
The framebuffer device was opened successfully.

The framebuffer device was mapped to memory successfully.

Please, help me, tell me what is wrong, or where to search for a solution??

Please accept my apology for this not being exactly an embedded
question, but as this is my favorite Linux group, this is the primary
place for me to seek for advice. (and in special cases this _can_ be
useful for embedded devices)

I am planning to do a highly automatically working backup program to be
released under GPL.

Same should use an external harddisk (or flash disk) and a DVD (or CD)
burner as backup media.

According to how long a version of the file is on the source tree, files
should be stored on both media, using a suitable algorithm: the external
disk should hold several versions of any file that changes between the
backup cycles (daily versions for some days, fewer versions for less
recent changes), long living versions finally are permanently stored on
the DVD instead. Thus both media together are hold an image of the
source tree, while the external harddisk is not likely to overflow. (Of
course special manual actions should be provided that move everything to
the DVD-chain, etc.) I plan to use a database (e.g. mySQL) to hold a
directory of all versions of all files on the backup media.

Some questions:

- Does such a project already exist so that I don't need to start from
scratch ?

- Does it make sense to use a compressing file system for the external
disk ? Which one is known as save ?

- How is it possible to write to a DVD ROM ? I suppose the easiest way
is to prepare the content on the harddisk and use a commandline tool to
move it on the DVD. Any pointers ?

Thanks a lot,

Hi All,

I'm working on a firewall/NAT router project using Debian Sarge 3.1.
Currently I have a hard disk based system, but I'd like it to run with a
128Mbyte CF card in a mini-ITX box. The firewall is working, but the
standard installation system is a little on the large side.

Someone suggested I could replace the init process with a user script and
only load those things I need, but init enables quite a few facilities, like
gracefully shutting down/ booting up, gettys etc., so I'd like to keep it
but maybe reduce the number of scripts run in /etc/rcS.d, and /etc/rc2.d
directories, and then remove all the packages and files I don't want.

Is this a sensible approach and is there an easy way to do this cutting
down? Would another init replacement, like runit, be better? I don't really
know enough yet to build it up from scratch and I really need the firewall
installed soon!

Thanks, any hints/suggestions would be gratefully received.

What am I doing wrong? Is there some known error with gcc? Is there
some patch? Please help me because I'm stuck I already googled

Hello,

We are planing to develop a new 32bit controller for robotic systems
based on Linux.
Required Features are real time support, CAN and Ethernet. The MPC5200
from Freescale on a Board from Phytec seams perfect.
Has somebody experience with Linux and this Processor? Is it easy to
implement and are all Features supported under Linux?
Or has somebody a suggestion on a similar Processor with is better
supported under Linux?

Best regards,
Syed Amer Gilani
