[beagleboard] Can not ping my beaglebone

What does ‘dmesg’ says when you connect the beaglebone to your PC?

Hi,

I meant the dmesg messages from your PC when you plug the USB.

Just do this:

  1. plug the beagle into USB port of your PC
  2. wait about 10 seconds
  3. type dmesg into your terminal (PC not beagle)
  4. cut few last line and paste it here

I would like to see what is being recognized by your PC since you said there is no TTY available at /dev (on your PC)

Regards,

Hi Julia,

Assuming the dmesg you sent below is from your PC and not from your beaglebone:

I’m having similar problems. When I dmesg I have a lot of this:
[11498.872071] eth0: Tx timeout - resetting

You have trouble with your network… probably not related to beaglebone

and this:
[11511.920161] usb 1-5.2: no configurations
[11511.920167] usb 1-5.2: can’t read configurations, error -22

Now, this might be your problem with beaglebone. For some reason it is not being recognized by your PC. Unfortunately I don´t know what is the “error -22”, perhaps someone else knows and tell us.

This happens with all USB ports in your PC?
How about another PC?
What does lsusb says?

Benito -
thank you for your help.

I DID figure that the flickering lights on my ethernet hub was not a good sign. I replaced the high powered ethernet card in my computer with a more linux friendly one, so I have access to another ethernet port in my wired networks. I manually configured eth3 (the new one) to an IP address of 169.254.118.1. But I cannot ping any 168.254.118.** IPs. So? What’s the addy of the bbone… Would a MAC address help me? Can I find that out?

Anyway, back in the terminal (computer prompt) my dmesg spit out a lot, endinging with
[ 57.548342] usb 1-5.2: can’t read configurations, error -22
[ 57.624141] usb 1-5.2: new high speed USB device using ehci_hcd and address 11
[ 57.644266] usb 1-5.2: no configurations
[ 57.644273] usb 1-5.2: can’t read configurations, error -22
[ 57.648072] hub 1-5:1.0: unable to enumerate USB device on port 2
[ 60.264105] usb 1-5.2: new high speed USB device using ehci_hcd and address 12
[ 60.357292] usb 1-5.2: configuration #1 chosen from 1 choice
[ 60.363488] cdc_acm 1-5.2:1.1: This device cannot do calls on its own. It is not a modem.
[ 60.363637] cdc_acm 1-5.2:1.1: ttyACM0: USB ACM device
[ 60.366224] cdc_acm 1-5.2:1.3: This device cannot do calls on its own. It is not a modem.
[ 60.366390] cdc_acm 1-5.2:1.3: ttyACM1: USB ACM device

ALSO - I found this:

Hope this helps! About to look into it now.

Why did you set this IP? Is it the IP of your network?

I think you might stick with IP address provided by DHCP server in your network unless you are absolutely sure what you are doing. Without details about your environment (network) it is very difficult to guess when this should work or not. In time, MAC has nothing to do with this, every ethernet board has a MAC address.

cheers,
