BB XM Rev C , various USB problems.

Hello folks,
Do anybody have a solution for the following issues:

1. Cold boot always fail. Always when I power up the board it reset at
random points during the kernel boot process, and restart the loader.
Most of the time it did not reach the point where the kernel starts /
sbin/init, however in few situations I saw it reboot during network
initialization and once or twice after the login prompt went on.
However, most of the time (> 80% ) when BB reset itself is during
kernel initialization of USB components.
After it keeps resetting for 3 to 15 times it finally boot properly.

2. In many cases after it boots, the usb0 network interface is not
present. Running ifconfig to set it up works sometimes, sometimes not.
It is random as far as I can tell. Typing "shutdown -r now" to reboot
the system (hot) usually fixes the problem and when it starts again
gets a fresh DHCP address.

3. MAC address for usb0 always change, forcing the DHCP server to
provide brand new addresses. Attempting to force it to a value in /etc/
network/interfaces have no effect.

4. USB cameras does not work at all. The cameras are detected, drivers
loaded OK and /dev/videoX entries are created properly. The capture
fail with "/dev/video0: Operation not permitted" and the kernel log
say:
"""

enough - trying again
Aug 6 04:46:02 beagleboard [12139.364410] gspca: bandwidth not wide
enough - trying again
"""

I tried 3 version of Angstrom images (original one, the one from
Circuitco and one I created with Narcisus). They all exhibit the same
boot issues. It is one of the new boards from DigiKey.

Follows a few snippets from dmesg (after reboots and network working
ok)

Any ideas ?

Thank you,
MTM

How are you powering the board?

Gerald

3

2 Amps plug.

4

At 5V? I would go higher on the current, 3A, especially if you have a USB camera hanging off the HUB. Make sure it is well regulated. If you don’t have a better supply handy, remove everything from the HUB and make sure you get your boot issues resolved. Then get the bigger supply and start working with the camera.

Hi Gerald,

At 5V? I would go higher on the current, 3A, especially if you have a USB
camera hanging off the HUB.

Yes 5V/2A. The boot issues happens without camera and even without an
ethernet cable plugged it.
Only the power supply and serial cable.

If it was a power supply issue I would expect the system to be
unstable and even reset during long time operations.
That is not the case. The board have cold boot instabilities, without
any USB device connected to it.
After "it finally get up" it is stable, and stays up and running even
after I plug in 3 USB cameras simultaneously.

I can try next week with a industrial power supply, just to be 100%
sure that this is not the issue.
But I personally rule it out already. Without any camera connected my
voltmeter indicates the same stable 5.03V as with all 3 cameras
plugged in. If there it is any voltage drop for connecting all 3
cameras it is under 0.01V and that shall not affect the electronics in
any way.

Thanks,
MTM

I suggest you request an RMA.

Hi,

I want to use arm neon intrinsics set for optimization.I want to build my my code and compile it using the Code Sourcery
Toolchain and then Port it on to the Beagle Board-xM. How to use
Neon Intrinsics in my Code. Will Beagle Board-xM support it…?

Thanks,

What does that have to do with usb problems? Also, wanting to use CSL, wtf?

You'll have a much better chance of getting useful answers if you
don't hijack threads! Write your own message with a subject that
describes your question.

What is a RMA ?

Thanks,
MTM

11

Return Material Authorization…it is where you send it in to the factory and have them see what, if anything, is wrong with the board and repair it if needed…

Might it be a problem with the new u-boot rather than the revision C
board itself? See separate thread on 'NAS device error' for a
repeatable problem with the network that is resolved by using the
earlier u-boot.
