Subject: [ARMedslack] ARMED kernel compile errors
Message-ID: <[email protected]>
Content-Type: text/plain; charset=ISO-8859-1; format=flowed
Dear Stuart!
Today i made a kernel configuration that suits my acer pda i mentioned a
week before, and then i tried to build it in the ARMedslack i installed
under qemu. I used the 2.6.30.5 kernel source .tgz you supplied with the
ARMedslack 12.2 distribution. The compilation was stopped with error.
The problematic file was vgacon.c. Since the vga text console is
necessary for me, i could not take it out from the kernel options. How
did you succeed to compile this kernel? What do you think i should do
with that? This was the gcc error message:

Neither QEMU nor the Kirkwood platforms provide VGA, so the kernels
don't have support for it.
Does the PDA really have VGA?
The default config for the N30 has not got VGA set -- it does have
Framebuffer set though -- most ARM devices use framebuffer: try using
that instead.

Subject: [ARMedslack] Mounting root filesystem
Message-ID: <[email protected]>
Content-Type: text/plain; charset=ISO-8859-1; format=flowed
Hi Stuart, Everyone!
I succeeded to compile the kernel with switching off the vga console as
you advised. I copied the root filesystem from the qemu image with the
installed ARMedslack onto an SD card. With fdisk i created three
partitions on it. One dos type with the kernel and the bootloader
(haret-0.3.8), one linux swap, and an ext2 with the root filesystem. I
inserted the card into the pda and started the bootloader. After the
penguin logo appeared and the kernel massages started coming up on the
pda console, the booting stopped with an error:
VFS: Cannot open root device "mmcblk0p3" or unknown-block(0,0)
On my laptop with x86 processor and Slackware 12.2, after i plug in an
SD card it can be seen in /dev/mmcblk0, and the partitions on it are
/dev/mmcblk0p1, /dev/mmcblk0p2, etc. Do you think this kind of naming
convention is also valid under the ARM environment. What do you think
could be the device name of an sd card inserted into a pda, and the
device names of the partitions on it?
Thanks:
Tibor Kendl

Hi
pda console, the booting stopped with an error: VFS: Cannot open root
device "mmcblk0p3" or unknown-block(0,0)
[..]
/dev/mmcblk0, and the partitions on it are /dev/mmcblk0p1,
/dev/mmcblk0p2, etc. Do you think this kind of naming convention is also
valid under the ARM environment.
It's most likely to be the same if you have just one of these devices.
The first thing I would do is to check whether you have the support
for the SD card compiled into the kernel.
If you have compiled the driver into the kernel, you ought to see
some output from it -- at a minimum you ought to see this:
[ 36.873037] mmc0: mvsdio driver initialized, lacking card detect (fall
back to polling)
This is what I see on my sheevaplug which does not have an SD card
in the slot.
Some of the information here may be helpful regarding the SD card:

I hope that helps.

Hi everybody,
Sun released Java SE binaries for embedded devices :
http://java.sun.com/javase/downloads/embedded.jsp
The following one works fine for me on armedslack-current on my
sheeva-plug (it is a month old install I have not been following
-current since then) :
ARMv5 Linux - Headless (Early Access)
* EABI, glibc 2.5, Soft Float, Little Endian
Just untar the archive and add the bin folder to your PATH environment
variable.
It requires registration and should stop working after 90 days.
Cheers
Frank

Hi Frank

http://java.sun.com/javase/downloads/embedded.jsp
Cool thanks - I did not know SUN were releasing Java
binaries for ARM.
Patrick asked directly for approval to include the x86 binary blobs into
Slackware, so I'll try and do the same for ARMedslack.
Beats the hell out of trying to compile the open source stuff ;-)
