Hi Neelima,

Couple things to make sure:

Are you using a USB 2.0 Hub between the beagleboard and your usb keyboard/mouse?
Can you provide a complete serial dump, including first power on too
the ubuntu login? (paste to pastebin.com)

Sorry, I've never used the NAND as the root file system so the wiki
doesn't cover that..

Regards,

Hi Robert,
  Yes I am using USB2.0 hub and it was working for angstrom
distribution.
Sorry I did not get what you mean by complete serial dump ,including
fits power on to the ubuntu login ,Do you mean to say dmesg when
booting.
Please let me know so that I can send lgs accordingly.

Regards
Neelima

Hi Neelima,

On my beagle's dmesg always seems to miss the start:

Registered protocol family 2
[128494.647949] IP route cache hash table entries: 1024 (order: 0, 4096 bytes)
[128494.648559] TCP established hash table entries: 4096 (order: 3, 32768 bytes)
[128494.648712] TCP bind hash table entries: 4096 (order: 2, 16384 bytes)
[128494.648803] TCP: Hash tables configured (established 4096 bind 4096)

So just capture the serial boot log,

Like: http://pastebin.com/m53eb9914

Hi Robert,

   I copied serial port log at http://pastebin.com/m4e3fd205
Fat32 partition had v2.6.29-oer32
and I built root filesystem using below command
sudo ./build-arm-rootfs --fqdn beagleboard --login ubuntu --password
temppwd --imagesize 3G --seed ubuntu-desktop,linux-firmware

I really appreciate your help in this matter

Hi Neelima,

For comparison, here's my pastebin using the same kernel:
http://pastebin.com/d3694d19

Major differences that could cause an error..

You had X-Loader 1.41 vs X-Loader 1.4.2 (but USB worked before)

Yours: Haven't seen this error before....
Spurious irq 95: 0xffffffdf, please flush posted write for irq 56
Spurious irq 95: 0xffffffdf, please flush posted write for irq 56

There should at least be a USB hub detected:

In Mine
usb 2-1: configuration #1 chosen from 1 choice
hub 2-1:1.0: USB hub found
hub 2-1:1.0: 4 ports detected

Very strange...

Hi Neelima,

Most of my beagles are running Debian Squeeze with a MOSTEC based
usb-ethernet adapter. (these build beagle kernel deb's and test gcc)

At work mostly ubuntu and angstrom.

I've had very good luck with rtl8187 based usb wifi adapters.

Regards,

In ubuntu is where the files ... the ethernet ....

I plugged the network cable in beagleboard. and did lsusb Realtek - RTL8150

10

Thanks Diego...

That one should be supported, not sure if anyone has ever tested it..

.config has: CONFIG_USB_RTL8150=y

When plugged into the beagleboard does it show up in dmesg or lsusb?

dmesg | grep rtl8

dmesg | grep eth

If that returns a result, you may have to do:

sudo ifconfig ethX up
sudo dhclient ethX

Regards,

11

But I need the ethernet in Angstrom

12

same kernel..

13

Hey Robert,
  Instead of building Rootfs is there any exiting rootfs available
for Ubuntu

neelima

Hi Neelima,

Sorry, I wasn't able to host them due to bandwidth limits, but I build
them the same way the wiki says..

Regards,

15

the angstrom identifies the Ethernet but he says NOT CONNECTED

16

Then you are very close...

Do the Angstrom equivalent of:

sudo ifconfig ethX up
sudo dhclient ethX

or use the Network Manager gui Angstrom provides..

Regards,

17

I was there but still not working, I need the Angstrom

18

Hey Robert,

  Is there any other way I can boot ubuntu on BB.I really need some
help with it .I would appreciate if you can help me with this.

Hi Neelima,

You could try an older 2.6.28 kernel... (just to see if usb works and
if this is a regression..)

Grab it from my archive location...
http://rcn-ee.homeip.net:81/dl/mirror/deb/kernel/CC-v2.6.28-79d042a-oer17

rename to "uImage"

Hi Robert,

appreciate you help.

Neelima
