BeagleBoard-xM Rev C, opkg update problem

Hi Vladimir,

A quick Google search returned this: http://www.electronsonradio.com/2011/07/angstrom-on-the-beagleboard-fixing-your-mac-address/

It suggests you use the uEnv.txt on your SD card to set optargs=”ethaddr=00:11:22:33:44:66″

You may also look for support on http://beagleboard.org/ and on our Linux forums.

Best regards,
Miroslav

Thank you for answer Miroslav...

Yes, I saw that post but it didn't work for me. I tried again and the result is same. I edited eEnv.txt file and added "optargs=”ethaddr=00:11:22:33:44:66″ " but during boot I got:

[    4.263203] smsc95xx 1-2.1:1.0: usb0: register 'smsc95xx' at usb-ehci-omap.0-2.1, smsc95xx USB 2.0 Ethernet, 26:c9:6f:83:df:3c

I, also, tried to implement patch which is provided but it seems to be the same behaviour. Have you any other advice?

Regards,

Vladimir

Hi,

I don't have the sources for the Angstrom U-Boot, but it should be something similar:

There should be a README file in the U-Boot folder, which states:

- Vendor Parameter Protection:

        U-Boot considers the values of the environment
        variables "serial#" (Board Serial Number) and
        "ethaddr" (Ethernet Address) to be parameters that
        are set once by the board vendor / manufacturer, and
        protects these variables from casual modification by
        the user. Once set, these variables are read-only,
        and write or delete attempts are rejected. You can
        change this behaviour:

        If CONFIG_ENV_OVERWRITE is #defined in your config
        file, the write protection for vendor parameters is
        completely disabled. Anybody can change or delete
        these parameters.

        Alternatively, if you #define _both_ CONFIG_ETHADDR
        _and_ CONFIG_OVERWRITE_ETHADDR_ONCE, a default
        Ethernet address is installed in the environment,
        which can be changed exactly ONCE by the user. [The
        serial# is unaffected by this, i. e. it remains
        read-only.]

        The same can be accomplished in a more flexible way
        for any variable by configuring the type of access
        to allow for those variables in the ".flags" variable
        or define CONFIG_ENV_FLAGS_LIST_STATIC.

There should be a board config file with all these defines, usually <u-boot_folder>/include/configs/<your_board>.h.

Inside it replace/add the following:

#define CONFIG_ETHADDR  <your ethernet address>

and then rebuild your U-Boot.

Best regards,
Miroslav

Hi Miroslav,

I'm using u-boot (as well as MLO file) from this site: http://downloads.angstrom-distribution.org/demo/beagleboard/ and I can't modify "<u-boot_folder>/include/configs/<your_board>.h". Is that means I can't set static MAC address for my Beagleboard - xM? Now, I can download packages from the Internet. I solved my problem with modifying "/etc/hosts" file. I added in "hosts" file:

188.40.83.200         www.angstrom-distribution.org

"188.40.83.200" is IP address of "www.angstrom-distribution.org" site. Now, I'm able to download packages from the Internet directly on the BeagleBoard-xM.

Best regards,

Vladimir

Without the source code files, you won't be able to try the proposed solution.

If you are not satisfied with your current solution, you can always download the source code files from the Andstrom project page and try what I have proposed.

Hi Miroslav,

For now, I'm satisfied with this solution. Anyway, thanks for your reply.

Best regards,

Vladimir
