xM machine type

Although the OMAP3 BeagleBoard is listed here:
http://www.arm.linux.org.uk/developer/machines/

I can't see the -xM version.

Is the list still active? I can't find the list on the Linaro site
either:
https://wiki.linaro.org/FindPage

Does the -xM board have a registered machine id yet? Thanks.

Its described on the beagleboard.org

It says not avialable till oct 1 although I traded emails with someone who is seeing kernel panics using it so he got one somehow

I also googled beagle baord c4 vs xM diffrences and found a pdf hw users manual

The angstrom verification page says hw verfication kernel for xM is not complete

I just bought a C4 works fine

Although the OMAP3 BeagleBoard is listed here:
ARM Linux - Developer - Machines

I can't see the -xM version.

The -xM uses the same 'id' as the original Beagle..

Is the list still active?

They've been shipping units to customers for a good month now... The
kernel panics can come from early "P" and "A1" revisions that shipped
before the production "A2" units. (bad memory).. Or a
kernel/u-boot/X-loader that is way too old to be running on the new
DM37xx that's on the xM beagle..

xM board uses same machine I’d. They are just different revisions.

Thanks, all.

I am in no way an expert so thanks.
I cc’d the peson who was having an issue with the xM

I am assuming these below are still valid for Angstrom from http://www.angstrom-distribution.org/demo/beagleboard/
I have a C4 but no external power besides the hub
I am in the process of trying this today

## What If…Some common problems and their fixes
- The kernel panics at random points during start-up.
Use the 5V external power supply. Sometimes the current via USB is not enough.
- Even with the 5V supply the kernel panics during start-up.
Ensure that you copied the uImage.bin file from the Angstrom filesystem into the boot partition. Compare md5 checksums to be sure.
- USB Ethernet doesn’t work at startup.
The culprit is the composite USB gadget driver. In etc/default/usb-gadget set USB_MODE='networking' and run the module reconfiguration script (name?).

The panic I had I believe is do to a bad image. I am slowly figuring more things out. I have been running off the external 5volt supply for all my work at this point.

I got sick last week so I did not get as much done. At this point I can build from tar images boot disk and systems, but I have yet to figure out how to set to boot options. (I think I know what needs to be done, just not how to get the tools together to do it.

Once I get more comfortable here I will go back to kernel building attempts.
