Linux kernel update

This is probably a little off topic for this list, but here goes.

It would be nice if we could update the Linux kernel romotely via GPRS modem.

I know this will be slow, but let's assume the we can get the new image onto the board via some remote connection.

It must be carried out with no user interaction.

I have done this before on other systems, but not updaing the kernel.

Is there a way from Linux userland for updating the flash image.

Perhaps a direct write to mtd2?

Looking for success stories from other users.

    Hmm Not quite sure what that response means??

    This is obviously not a simple topic , and from my initial investigations not easy to implement.

    Our approach so far is to remove as many custom componenst as possible from the kernel and make these loadable modules.

    We can then replace these as required during an update.

    The one sticking point is our camera driver.

    V4L and VPFE are dependant on this, to remove this from the kernel seems to be opening a can of wroms.

     

    Will try to update this post on aour progress.
