VFS not finding a valid FAT FS ???

2009-11-12T14:11:51Z

Hello,

I got a new microSD card and it turns out that the original card was a dud ... so I fired up gparted again and got everything put where it needed to be ... at least I thought I did, but when I boot now I get the following set of messages during boot:

mmcblk0: mmc0:1234 SA02G 1927168KiB
mmcblk0: p1 p2
.
.
.
root: mount: special device /dev/mmcblk0p1 does not exist
.
.
.
FAT: Invalid media media value (0x00)
VFS: Can't find a valid FAT filesystem on mmcblk0

And then it continues to boot using the original rootfs in Gumstix memory.

If I run fdisk on mmvblk0 I get:

Disk /dev/mmcblk0: 1973 MB, 1973420032 bytes
255 heads, 63 sectors/track, 239 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

        Device Boot    Start       End    Blocks   Id System
/dev/mmcblk0p1   *           1           8       64228+   6 FAT16
/dev/mmcblk0p2               9         239     1855507+ 83 Linux

Or if I run fsch on it:

fsck 1.38 (30-Jun-2005)
dosfsck 2.11, 12 Mar 2005, FAT32, LFN
/dev/mmcblk0p1: 3 files, 489/32042 clusters

The only 'weird' thing is that when I ran mkfs.cfat I used the -F 16 flag so it would be fat16 but it show up as f32 ???

I saw one or two messages that talked about this problem, but never with a resolution. Any ideas on what is causing this?

Respectfully,

Hi,

I would be interested in exploring this setup. Could you please let me
know the frame rate achieved during those 30 seconds ?

Thanks,

usbNet on overo earth

2009-11-12T11:36:45Z

So I am a total newbie to gumstix but I'm trying to use one for a project at uni. It's an overo earth in a summit expansion board. I have got it booting fine but now I am trying to get usbnet working between it and my netbook. All the instructions online refer to usb0 on the gumstix which I just don't have, im running omap3-desktop-image-overo-200910121635 on the gumstix and ubuntu-9.04 on the netbook. The usb cable is going from the usb-otg on the summit board to the netbook which I think is correct but don't really know. All the results I am getting online seem to be for people having problems doing usbnet using the verdex.

Does anyone have any ideas? or can point me in the right direction? I have been on the wiki but again without a usb0 I don't know what to do.

Thanks

This worked for me. :)

Just rename getline to getline2 in:

Re: Sending images over wifi

Hi

I plugged in a Belkin usb 2.0 wifi adapter and noticed a marked improvement in frame rate, however, this only lasted for a 30 seconds while lots of error messages were output to the console. They had the following form:

If you want to know why then search the archives. I haven't kept up with any of the changes, but last I heard was the speed was greatly limited due to how it was currently implemented.

Subject: [Gumstix-users] Sending images over wifi

Hi

I have been trying to acquire and transmit 480x640 images from a Point Grey
Research camera connected to an Overo fire to a development machine for
processing. At present I am using some opencv C++ code which takes the
acquired image and sends it wirelessly through a socket to the development
machine: this scheme results in a very low frame rate. I am looking for
suggestions for getting a higher frame rate and what the best method is for
getting images back to the development machine for processing?

Your help is much appreciated

Recompile kernel

2009-11-12T00:06:13Z

Hello everyone

I have compiled an image for Overo (air) using the tutorial.
Now I just need to recompile the kernel to add & remove some modules.

There is a post on doing this by copying linux-omap3/depconfig/etc to user.collections
BUT it results with the kernel being upgraded to 2.6.31

Is there a way to just modify the config file and make OE re-build the kernel like it does during "bitbake omap3-console-image" ?
(No upgrades, no changes, just different modules)

Thanks in advance for your help

Wifi stopps working on verdex pro

2009-11-11T14:39:29Z

Hi all,

I am using a verdex pro together with netpro-vx and the wifi module.

After some days my wifi suddenly stoppes working and the blue led
stoppes blinking.

In /var/log/messages I found the following line:
Nov 11 21:20:23 gumstix-custom-verdex user.info kernel: NETDEV WATCHDOG:
wlan0: transmit timed out

I am using static IP configuration. Here is my /etc/network/interfaces:

auto lo
iface lo inet loopback

# auto eth0
iface eth0 inet dhcp

auto wlan0
iface wlan0 inet static
pre-up /sbin/iwconfig $IFACE key 0B231BE2ECE56734CAD96917DC key
open essid jack txpower auto power on
address 192.168.7.95
netmask 255.255.255.0
broadcast 192.168.7.255
gateway 192.168.7.50

iface usb0 inet static
address 192.168.0.202
netmask 255.255.255.0
network 192.168.0.0
gateway 192.168.0.200

When I am trying to execute iwconfig, the tool hangs.

The only way to restart wifi is to reboot the gumstix.

Can someone help me with the problem?

Regards,
Janki

Re: microSD booting ...

> I wonder how long 2gb cards will still be available...

Actually for quite some time I guess. Main reason: That 2GB is the highest
capacity in the original SD specification. Next size (4GB) is SDHC and
thereby not guaranteed compliant with all old SD (non SDHC compatible)
equipment...

I would therefore guess, that 2GB will still exist for quite a while, but it
might though be that 4GB and 8GB will die on behalf of 16GB and 32GB cards -
I totally agree :-)...

I would think so, too. Try an other card. They are so cheap now, I
wonder how long 2gb cards will still be available...

microSD booting ...

2009-11-11T11:43:52Z

I was wondering if I am missing something ... it has been a while since I dove head first into linux, so forgive me :)

I recently picked up a 2 gb sandisk card. And then did the following:

Updated the verdex conf file to make sure it would build fat, ext2, and mmcroot
Deleted my gumstix-oe/tmp directory
Rebuilt everything to make sure it was totally clean using gumstix-basic-image (even ran svn update)
used gparted to create the partitions and format them according to the wiki page:

64 mb fat16 parititon labeled gum-uImage
1.7 gb ext2 partition labeled gum-rootfs

Copied the uImage file and factory script to the fat partition
extracted the rootfs to the ext2 partition
unmounted the two partitions
plooped the microSD card into my Verdex Pro-XM4
fired up minicom and booted the gumstix
It seems to read the card fine and it get past where most kernels panic:

Instruction Cache is ON
Found gumstix-factory.script on MMC...

I have tried running 'Check' from gparted and it originally said that the sectors were not what Windows would expect, so I moved the card over to a windows machine and formatted it there and redid the last couple of steps to files on the drive and test. This did not fix anything :( I have noticed that when this occurs, when I try to clear out the gum-rootfs partition, I get stale file handle messages.

I have searched through Nabble and Google to no avail. There were some threads about using a ram disk to boot, but I am not sure if the level of effort is appropriate / necessary to get the microSD card going. I have tried the prebuilt images from the Steve's site, but they still have the strange I/O errors ... I am starting to think that I might be suffering from a faulty card, but then again, my host linux box is not complaining about it ..

Any thoughts or tips would be greatly appreciated!

Trying to make new image to use omap3camera kernel on gitorious

2009-11-11T11:21:45Z

I am trying to integrate the kernel from gitorious.org/omap3camera
into a bitbake image and I am new to this process.

I created a user.collection/recipes/linux/linux-omap3_2.6.32-rc5.bb
for this target with the following:

require linux.inc

DESCRIPTION = "Linux kernel for OMAP3 processors"
KERNEL_IMAGETYPE = "uImage"

COMPATIBLE_MACHINE = "beagleboard|omap3evm|overo"

PV = "2.6.32-rc5"
PR = "r1"

SRC_URI = "git://gitorious.org/omap3camera/
mainline.git;branch=devel;protocol=git \
file://defconfig \
"
S = "${WORKDIR}/git"

Basically, I changed the SRC_URI to point to the GIT repository (I
think)

I get the following output which shows the system is not getting the
kernel source, but I am not sure what I did wrong. Any suggestions?

Use of USB OTG port on Summit board as USB client

2009-11-11T10:59:53Z

If the USB on-the-go (OTG) port on the Summit board is attached to a USB hub as if it is a client but no other element of the USB system is OTG enabled, will the board power up automatically in a USB client configuration? Or does this need to be programmed to achieve it?

Re: Sending images over wifi

2009-11-11T09:44:40Z

I'd try using a USB 2.0 Wireless adapter, and seeing if that doesn't perform better.

If you want to know why then search the archives. I haven't kept up with any of the changes, but last I heard was the speed was greatly limited due to how it was currently implemented.

Subject: [Gumstix-users] Sending images over wifi

Hi

I have been trying to acquire and transmit 480x640 images from a Point Grey
Research camera connected to an Overo fire to a development machine for
processing. At present I am using some opencv C++ code which takes the
acquired image and sends it wirelessly through a socket to the development
machine: this scheme results in a very low frame rate. I am looking for
suggestions for getting a higher frame rate and what the best method is for
getting images back to the development machine for processing?

Your help is much appreciated

Re: Sending images over wifi

2009-11-11T07:48:35Z

Well, first off, how are you sending them? is the socket opened for
UDP? or tcp? TCP requires a considerable amount of overhead on the
line to ensure packet delivery.

Are you asking for each frame? or just sending them non stop?

To get the frame rates up, you want to stream them to the receiver
over UDP, not TCP, for starters. Encapsulate them with something like
mpeg so that you can extract each frame at the receiving end. That
would help speed things up alot. If your application can tolerate the
occasional dropped packet/corrupted frame, it should work out well for
you.

maybe you have a similar problem than I had some time ago (thread http://old.nabble.com/Re:-forwarding-or-bridging-from-wlan0-to-eth0-with-td18719061.html): does your wireless device you try to ping have defined your gumstix wlan as default gateway?

Re: Questions on modifications to i2c-io on openembedded

2009-11-10T19:43:50Z

And when I shutdown, it does flash a message stating that robostix is shutting down. (Which probably means that it is there on the image)
So hopefully I have done the bitbake rebuild properly.

Just another thing. I had rad on a post on the mailing list that after recompiling the gumstix basic image (after uncommenting robostix and commenting lcd and touch screen) I would get the uisp command. After flashing I have not got the uisp command. I did ./uisp and find uisp unsuccessfully.

I believe the rest of the stuff like i2c-load will come from the robostix package.

hi

I wanted to send my own values to the robostix via I2C. I had done this on Buildroot.

On the Gumstix side there were two files that needed to be altered (with Buildroot). robostix/gumstix/Common/i2c-io-api.h and i2c-io-api.c

I found com.gumstix.collection/packages/i2c/files/i2c-io-api.h

But couldn't find i2c-io-api.c? I searched for it but didn't get it.

A sub-question: As far as the robostix chain I could simply copy the robostix folder from my buildroot that I used to have for a Basix (Not that it matters). So all my changes would carry though.

Is there a better way of doing this?

I bitbaked robostix and it completed successfully. Couldn't find the robostix package? I assume it is an ipkg file. From what I understand I need to scp this to the gumstix and then install it using the package manager. I have rebuilt gumstix-basic-image after uncommenting robostix and commenting lcd and touchscreen.

Also I have my own program that runs on the gumstix. It is a single c file. I call functions I2C_IO_GetADC and also a new one that is SETPWM that I had created. I had essentially replaced the i2c-io file with my program file in the robostix/gumstix/i2c-io folder in buildroot. And I used to use the same Makefile. Could I just modify the file i2c-io (or replace it with my program) and replace it with my and then just bitbake robostix. And then after installing this package I will hopefully be able to run my program.

Any comments/suggestions?

Thanks in advance.

Re: Questions on modifications to i2c-io on openembedded

2009-11-10T19:42:03Z

Just another thing. I had rad on a post on the mailing list that after recompiling the gumstix basic image (after uncommenting robostix and commenting lcd and touch screen) I would get the uisp command. After flashing I have not got the uisp command. I did ./uisp and find uisp unsuccessfully.

I believe the rest of the stuff like i2c-load will come from the robostix package.

Also I have my own program that runs on the gumstix. It is a single c file. I call functions I2C_IO_GetADC and also a new one that is SETPWM that I had created. I had essentially replaced the i2c-io file with my program file in the robostix/gumstix/i2c-io folder in buildroot. And I used to use the same Makefile.

Hi,

The kernel module for the NIC is not loaded by default. Try

Re: Using Samsung 800X480 LCD with Palo 43

2009-11-10T11:44:37Z

Hello

Thanks everyone for your valuable contributions. I too just bought this lcd to work with my gumstix system.

my question is that gumstix was out of the Palo43 board and I bought the new chestnut board. Does anyone here has any experience modifying a chestnut board to work with this lcd ?

Bonus question : why cut the copper trace rather than lifting the pin on the connector ?

Thanks a lot

Gumstix Verdex XL6P Bridge

2009-11-10T09:04:25Z

I am trying to bridge eth0 and wlan0 using a Gumstix XL6P (ie. without using routing table entries on equipment connecting to the Gumstix). I believe I need to set up a bridge using brctl, enable ip forwarding, and issue the following iptables commands to make this work:

iptables –t nat –A POSTROUTING –s 192.168.1.0/24 –d 192.168.1.0/24 –j ACCEPT

iptables –t nat –A POSTROUTING –s 192.168.1.0/24 –j MASQUERADE

Currently, I am unable to get the iptables commands to work. The Gumstix gives an error when issuing the iptables command that states the 'nat' table cannot be found. Also it will not automatically load the ip_tables modules (I have manually loaded the iptables modules with insmod to get iptables to work - ip_tables, iptable_filter, x_tables, nfnetlink, nf_conntrack, nf_nat, and ipt_MASQUERADE).

Does anyone know how to make bridging between wlan0 and eth0 work? Does this seem to be the correct process? Does anyone have any tips to get iptables working properly?

I have included a detailed description of my process below. I am using the 2.6.21 kernel with the following options enabled (basically bridging and all network packet filtering enabled as modules except for obsolete items):

Note that I have tried removing the network packet filtering framework from the kernel configuration (as I believe it is an iptables firewall issue preventing packets from forwarding through the bridge), but when I do this brctl gives the following errors:
bridge: Unknown symbol nf_hook_slow
bridge: Unknown symbol nf_hooks

I installed bridge-utils, iptables, kernel-module-ipt-masquerade, and iptables-utils using ipkg. And, I enabled ip forwarding in the /etc/network/options file.

I created the bridge by adding the following lines to the /etc/network/interfaces file:

# BEGIN BRIDGE ATTEMPT

auto br0
iface br0 inet static
address 192.168.1.56
netmask 255.255.255.0

pre-up brctl addbr br0
pre-up brctl addif br0 wlan0
pre-up brctl addif br0 eth0
post-down brctl delbr br0

auto eth0
iface eth0 inet static
address 0.0.0.0
netmask 255.255.255.0

auto wlan0
iface wlan0 inet static
wireless-essid Gumstix_Test
address 0.0.0.0
netmask 255.255.255.0

# END BRIDGE ATTEMPT

This creates a bridge that can ping the wired and wireless (AP) interfaces connected to it and vice versa. However, the wired unit connected to the Gumstix cannot ping the wireless AP through the Gumstix.

Thanks for your help.

Re: Getting GCC on Overo

On the Angstrom site they have a package browser that's useful.

I agree with Thierry, I think you can ignore the hicolor errors.

I don't get those errors running opkg now.

Re: Getting GCC on Overo

Hi,

I believe the errors about hicolor-icon-theme do not prevent opkg from
working. It just fails on hicolor-icon-theme every time and that task
remains in its queue.

The real question is why do we have an icon theme in a console
image??? It just eats up valuable space.

Thierry

Thanks for the info. gcc was successful installed. Now try to get glib installed (>= 2.6).

And my main pain is the inability to use opkg / ipkg.

root@overo:/# ipkg install nbd

postinst script returned status 127

I only need the console mode so I have used the default image (omap3-console-image).
It appears that opkg doesn't work on the default image*

Anyone got opkg/ipkg to work ?

Thanks

Overo Fire + Chestnut43 - Ethernet not working

2009-11-09T17:34:47Z

Hello,

I've just unpacked my Overo Fire + Chestnut43 + LCD43 and I am trying to using the Ethernet port onboard on the chestnut43, but the Angstrom distro does not even detect it. I connect a cable to it but I see no lights (no leds?). Is there a driver/firmware I need to upload to it to get it working?

Thanks,

Marcus

Re: Overo GPMC questions

Hi Scott,

No - This is unfortunately not safe - OMAP boots from CS0 and uses Wait0. AFAIR you can share the wait-line between multiple devices, although I'm not 100% sure and it would require all the devices to have open-drain output for driving the signal - Remember to put a pull-up on the signal as well. In case you can find another wait signal (than wait0) I think this is the most secure path.

More info about NAND booting and GPMC configuration please consult the OMAP3530 TRM (spruf98c.pdf) chapter 25.4.7.4 and chapter 11.1...

Mcspi1_cs3 is only available on ball AB2, which is as well the only place for HSUSB2_D2 (for the USB Host PHY), which tells why it's not brought to the connector :-)

Best regards - Good luck - In case of further questions please don't hesitate to ask

Re: Overo GPMC questions

2009-11-09T14:03:49Z

Hi Søren,

Thanks for your quick reply.

Do you know which GPMC chip select signal and wait signal are used by the NAND? Or is it safe to assume that it's not one brought out to J4 connector? :)

Or a related topic, do you why mcspi1_cs3 wasn't brought out to J1 or J4? All the other mcspi1 signals seem to be there. Could it have been brought out, and the documentation doesn't clearly show it?

thanks again,
Scott

Hi Scott,

The GPMC is connected to the PoP NAND chip on the Overo itself. With respect
to loading considerations, you can get the datasheet from Micron after
registering and signing an NDA. Alternatively you can assume it's loading as
a "standard" NAND device in case you have a datasheet for such one at hand.
AFAIR it's loading with less than 10pF/pin

Good luck - Good luck
Søren

something wrong with gumstix.net?

2009-11-09T13:49:57Z

Hi,

I have just unpacked my new Overo Earth + Chestnut43 and was trying to
follow the basic how-tos, but there seems to be something wrong with
(at least) the Overo: Setup and Programming section of the
documentation section: every link (Overview, Getting Started, etc)
takes me back to the top of the tree to select from User How-To's,
Setup and Programming or Hardware.
Someone please....

thanks is advance

How to Customize Linux Kernel

2009-11-09T12:05:59Z

Hi all

I wonder if there are some guys who know how to customize the linux kernel on gumstix e.g. remove some unnecessary drivers, protocols and services? In this way maybe I can reduce the size of the linux kernel. Its current size is about 1M bytes. If there is any website or material from which I can learn something on this, please tell me. Thank you very much and appreciate your help.
