no wlan0 on overo airstorm/yocto/console build

Kerry Dungan
The system boots nicely. However, using iwconfig only shows eth0 and lo with no wireless options. There is no wlan0. Thus, I followed the instructions on the link

http://gumstix.org/software-development/how-to/252-bring-up-wifi-on-a-yocto-project-image.html

Still no wlan0 on iwconfig. My only clues to what is going wrong comes from systemctl reporting dhclient.service faiiled and the [hidden email] is stuck in activating state. At this point, I just want to see wlan0 show up with wireless options to move forward from there.

Any suggestions will be helpful.

Thanks

Hi Kerry, are kernel modules loaded? 
Try 'lsmod' in the terminal.

Let me know!

I also had similar problem before with omap3.2 from the git tree, and that was due to Marvell Firmware incompatibility with new Libtertas version or problem with newer udev, or other reasons.
Do you manually install the wireless firmware? If not, try search forum on how to do that. 
I didn't manage to solve my problem with 3.2, so I switched to omap3.5 and boom everything works...

I did no manual install, just the images at http://gumstix.org/download-prebuilt-images.html. The table says version 3.5.

"lsmod shows no module", did you do according to this page http://gumstix.org/basic-cross-compilation.html ? the last step make modules_iinstal.

To summarize, I ran lsmod and found no modules running. Should I expect some modules to load to get wlan0 up?

Also, I ran 'uname -a' and Linux overo 3.5.0 is running.

Check /lib/modules, what's under that folder?

I didn't manage to solve my problem with 3.2, so I switched to omap3.5 and boom everything works...

Re: no wlan0 on overo airstorm/yocto/console build

Kerry Dungan
In lib modules there is a directory /lib/modules/3.5.7 with several module files.

As for the firmware suggestion, /lib/firmware contains the sd8686.bin file.

For some reason the modules aren't loading. What file should load the modules?

Kerry, can you try this root file system instead? http://s3-us-west-2.amazonaws.com/gumstix-yocto/Releases/2013-08-09/overo/dev/gumstix-console-image-overo.tar.bz2

This is the original that belongs the rest of the image.

Let me know!

Re: no wlan0 on overo airstorm/yocto/console build

Kerry Dungan
Yes, the rootfs http://s3-us-west-2.amazonaws.com/gumstix-yocto/Releases/2013-08-09/overo/dev/gumstix-console-image-overo.tar.bz2 that is associated with uImage 3.5.0 loads modules and iwconfig, ifconfig, wpa_supplicant, etc. work fine. However, the rootfs is missing the dhclient application. Someone must have recognized this problem and generated the rootfs https://s3-us-west-2.amazonaws.com/yocto/dhclient-issue/gumstix-console-image-overo.tar.bz2 that is associated with kernel 3.5.7. Notice the build even says dhclient-issue in the directory tree.

The problem at http://gumstix.org/download-prebuilt-images.html for yocto overo is the uImage for kernel 3.5.0 and is not compatible with the posted console rootfs that is based on 3.5.7.

To move forward, I recommend that gumstix posts a rootfs and uImage based on the same kernel that supports dhclient. Otherwise, any customer that wants to use wifi with wpa/wpa2 and console will have the same problem.

For now, I am forced to learn how to build my own uImage and rootfs, which is not where I wanted to spend my time. If anyone has a quick guide on how to build the rootfs and uImage, I would be appreciative.

Thanks

Hi Kerry, what you said is exactly correct and is my mistake. 
I will post the correct images today.

Thanks!

Do you manually install the wireless firmware? If not, try search forum on how to do that. 
I didn't manage to solve my problem with 3.2, so I switched to omap3.5 and boom everything works...

Kerry, if you are familiar with udhcpc, please try it out. It is already included in the original image. 
In the meanwhile,  I will cook up an image with dhclient using the Dylan release. I was hoping to get you an image by now, but I am running into build issues. 

Thanks for spotting this problem btw!

This is the original that belongs the rest of the image.

Let me know!

Do you manually install the wireless firmware? If not, try search forum on how to do that. 
I didn't manage to solve my problem with 3.2, so I switched to omap3.5 and boom everything works...

Still no wlan0 on iwconfig. My only clues to what is going wrong comes from systemctl reporting dhclient.service faiiled and the [hidden email] is stuck in activating state. At this point, I just want to see wlan0 show up with wireless options to move forward from there.

Any suggestions will be helpful.

Re: no wlan0 on overo airstorm/yocto/console build

Kerry Dungan
I used the 3.5.0 images along with the instructions on http://wiki.gumstix.org/index.php?title=Overo_Wifi. wpa_supplicant automatically called udhcpc and I am successfully connected. In my case, the 3.5.7 dhclient fix may not be necessary. When you get the uniform 3.5.7 (or later) build, complete, I will give it a try. I'll have to find the file that chooses which dhcp client to use and experiment. For now, I'm up and running.

Thanks...Kerry

Thanks for spotting this problem btw!

Yes, the rootfs http://s3-us-west-2.amazonaws.com/gumstix-yocto/Releases/2013-08-09/overo/dev/gumstix-console-image-overo.tar.bz2 that is associated with uImage 3.5.0 loads modules and iwconfig, ifconfig, wpa_supplicant, etc. work fine. However, the rootfs is missing the dhclient application. Someone must have recognized this problem and generated the rootfs https://s3-us-west-2.amazonaws.com/yocto/dhclient-issue/gumstix-console-image-overo.tar.bz2 that is associated with kernel 3.5.7. Notice the build even says dhclient-issue in the directory tree.

The problem at http://gumstix.org/download-prebuilt-images.html for yocto overo is the uImage for kernel 3.5.0 and is not compatible with the posted console rootfs that is based on 3.5.7.

To move forward, I recommend that gumstix posts a rootfs and uImage based on the same kernel that supports dhclient. Otherwise, any customer that wants to use wifi with wpa/wpa2 and console will have the same problem.

For now, I am forced to learn how to build my own uImage and rootfs, which is not where I wanted to spend my time. If anyone has a quick guide on how to build the rootfs and uImage, I would be appreciative.

Yes, the rootfs http://s3-us-west-2.amazonaws.com/gumstix-yocto/Releases/2013-08-09/overo/dev/gumstix-console-image-overo.tar.bz2 that is associated with uImage 3.5.0 loads modules and iwconfig, ifconfig, wpa_supplicant, etc. work fine. However, the rootfs is missing the dhclient application. Someone must have recognized this problem and generated the rootfs https://s3-us-west-2.amazonaws.com/yocto/dhclient-issue/gumstix-console-image-overo.tar.bz2 that is associated with kernel 3.5.7. Notice the build even says dhclient-issue in the directory tree.

The problem at http://gumstix.org/download-prebuilt-images.html for yocto overo is the uImage for kernel 3.5.0 and is not compatible with the posted console rootfs that is based on 3.5.7.

To move forward, I recommend that gumstix posts a rootfs and uImage based on the same kernel that supports dhclient. Otherwise, any customer that wants to use wifi with wpa/wpa2 and console will have the same problem.

For now, I am forced to learn how to build my own uImage and rootfs, which is not where I wanted to spend my time. If anyone has a quick guide on how to build the rootfs and uImage, I would be appreciative.

Thanks

Kerry, can you try this root file system instead? http://s3-us-west-2.amazonaws.com/gumstix-yocto/Releases/2013-08-09/overo/dev/gumstix-console-image-overo.tar.bz2

This is the original that belongs the rest of the image.

Let me know!

Try depmod ? Also take a look at the dmesg output.

In lib modules there is a directory /lib/modules/3.5.7 with several module files.

As for the firmware suggestion, /lib/firmware contains the sd8686.bin file.

For some reason the modules aren't loading. What file should load the modules?

Check /lib/modules, what's under that folder?

I did not compile my image. I used one of the pre-build images. Do you recommend that I build my own?

Thanks

"lsmod shows no module", did you do according to this page http://gumstix.org/basic-cross-compilation.html ? the last step make modules_iinstal.

I did no manual install, just the images at http://gumstix.org/download-prebuilt-images.html. The table says version 3.5.

I also had similar problem before with omap3.2 from the git tree, and that was due to Marvell Firmware incompatibility with new Libtertas version or problem with newer udev, or other reasons.
Do you manually install the wireless firmware? If not, try search forum on how to do that. 
I didn't manage to solve my problem with 3.2, so I switched to omap3.5 and boom everything works...

The system boots nicely. However, using iwconfig only shows eth0 and lo with no wireless options. There is no wlan0. Thus, I followed the instructions on the link

http://gumstix.org/software-development/how-to/252-bring-up-wifi-on-a-yocto-project-image.html

Still no wlan0 on iwconfig. My only clues to what is going wrong comes from systemctl reporting dhclient.service faiiled and the [hidden email] is stuck in activating state. At this point, I just want to see wlan0 show up with wireless options to move forward from there.

Any suggestions will be helpful.

Thanks
