My hub on BB Mx don't work sometimes, so i can't use mouse o keyboard.
Why ?
In my sd card I have Angstrom and I use BB Mx.
Can you help me ?
Another think...
my u-boot file is not optimized and I see my LCD screen badly, for
example i see black, red.
can you post me your u-boot file or another solution ?
Thank you.
If your hub doesn’t work you need a new one. If your BB doesn’t work, the hub may not be providing sufficient power.

I have a BB Mx, I powering my BB with a usb cable.
Today I have copied a MLO, u-boot and uImage of Angstrom and my mouse
turned on (hub working), but on my screen appeared:
[beagleboard.org] <- logo
INIT: version 2.86 booting
Please wait: booting...
Remouning root file system...
that's all!
The leds from sd-card turning off and the boot freezing here.
Maybe is the u-boot or the MLO or the uImage the problem ?
Because now my hub working (the boot actived my usb port) but the boot
doesn't finish.
What's the problem ?
Thank you.
Have you tried booting without the mouse and keyboard attached? I have encountered different behaviour booting Android and Ubuntu with a keyboard and mouse attached to a powered USB hub. I don’t know anything about power settings but a know you can detect whether you’re experiencing power problems by a process of elimination. I have two mice and one is 5V 100 mA and the other 3V so I use the 3V with the BB.

Hi,
I think you have a BB xM, (there is no BB Mx, so Mx is probably a typo). Your problems are probably caused by not supplying enough power. The integrated USB hub on the BB xM needs more power than can be supplied by the USB OTG cable. You must get a regulated 5 V power supply of at least 2 A if you want to use USB devices and video output. I use a 5 V, 3 A supply with my BB xM rev C and have not had any problems using a USB keyboard and mouse, with video output while running Angstrom or Ubuntu.

It's the same.
On my LCD screen i see the same things.
When appear "Remounting root file system" the system freeze.
I've created the SD image from Angstrom site and I wrote it on my SD.
but the system doesn't start.
Maybe my uImage is bad or my root file system.
Where can I download a correct filesystem ?
In Narcissus (Angstrom site) I followed this step:
- machine: beagleboard
- filename: beagle-image
- complexity: advanced
- release: 2011.03
- base system: extended
- dev manager: kernel
- init manager: sysvinit
- image type: omap SD image
- manifest: no
- sdk type: none
- user environment: X11
and then :
gunzip beagle-image-image-beagleboard-sd-4GiB.img.gz
dd if=beagle-image-image-beagleboard-sd-4GiB.img of=/dev/sdb bs=1M
sync
and then I putted my SD on my BB Mx.
What's wrong ?
Thank you.
