[Alexander Stein]

Hello,

Best regards,
Alexander

After a bit of googling, it looks like there are scattered URL
references to a no-longer-available "oopslog.c", written by the author
of mtdoops, Richard Purdie. I CC'd him at his last-known address from
the git logs, but he doesn't seem to have touched this in a while.

AFAIK, the output from mtdoops is just plain text data (not
compressed), so you can just dump it straight from the /dev/mtdX
(where X is the MTD number) with something like 'cat /dev/mtdX'. Of
course, that will not account for when the ring buffer wraps around
nor if there are bad blocks.

P.S. With a little more digging, I found a source tarball in the Maemo
archives that contains oopslog.c. It's a very simple program, and I
haven't tested it. Use at your own risk:

You've found the code that works with that setup, I haven't touched it
in a long time...

Cheers,

Ah, sp-oops-extract seems to be what I looked for. Thanks a lot!
