problems with USB-host at C2

Hi Al!!

I have a brand new EBVBeagle where C2 mark is printed. The board boots fine with the supplied SD card and I get to Angstrom showing at a DVI-panel. Then I try to connect mouse to the USB-host connector on the board and nothing happens (I expect to move a mouse pointer over the screen). So I’ve read using a high-speed USB-hub, connected to the host connector, and I plug in one which is marked as “HI-SPEED SERTIFIED”. I plug a mouse into that hub and nothing happens.

Can any one suggest what can be wrong at the brand new EBVBeagle? As a software I use everything from the card suplied with the board, nothing compiled myself.

Any help is appreciated!

regards,
Max

Since EBV doesn't seem to communicate with angstrom developers *at all* I don't know what's on the SD card, I recommend creating a brand new one from official angstrom (e.g. narcissus).

Dear Koen,

I’ve just compiled X11-image prom the stable branch and formatted new 2G SD card as described on eLinux. So EBVBeagle boots to Angstrom and:

  1. no ttyACM0 device in u-boot
  2. USB host does not detect any connected devices

I just don’t understand why the latest OE environment (stable of course) does not include ACM device?

May be the problem is that x-loader burned in EBVBeagle does not contain necessary code for proper USB initialization? I guess booting from SD card with Angstrom uImage and filesystem is not enough…

Dear Koen,

Correct, all the uboots with MUSB support are broken. Maybe versions more recent than 2009.11 might work with MUSB.

2) USB host does not detect any connected devices

Don't know about that, my C3 EHCI works fine, but I use the u-boot from http://www.angstrom-distribution.org/demo/beagleboard/

Though, unrelated here, I’ve observed while trying to run Android, the mouse does not work if I connect it after booting, but works if the USB mouse is already connected before power-up. Though this is strange and its quite possible I might have missed something, I think you can give it a try too.

how can I build the same u-boot?
