[U-Boot-Users] Multi-Image File Creation
I think I've seen this question posted before but I haven't been able to find it.
Is there a way to extract the vmlinux.gz image from a U-Boot multi-image? I think it's something like this but I'm guessing I need the original vmlinux.gz size -
# strip the wrapper dd if=uImage.initrd bs=76 skip=1 of=uImage_initrd.stripped
# extract the gzipped kernel dd if=uImage_initrd.stripped of=vmlinux.gz bs=??? count=??? skip=???
Thanks in advance for any info.

It took me just 2 minutes to search the mailing list archive (which appears to be warking at the moment - big surprise!). Here is what I got:
http://sourceforge.net/mailarchive/message.php?msg_id=5849825
And now for the funny part of the story: guess who was asking this question half a year ago, and received a detailed reply???
Guess who???
Don't you remember???
It was a person named "Tom Guilliams tguilliams@san.rr.com".
Funny coincidence, isn't it?
[No, I ain't going to make this a FAQ just because the same persons asks the same question againa and again.]

I knew I asked a similar question some time ago and used that info you gave me since.
I didn't word my questions correctly below and sorry for wasting your time. I have since written an app to return the image sizes to suit my needs. I needed something was a little easier to do than parsing the output of the "mkimage -l" app.
I was not aware they added a search bar to the SourceForge sight. At the time I wrote the previous email you're referring to, there was not such a thing. My apolgies again.
