[U-Boot] Problem with SD card and ext2ls

[U-Boot] Problem with SD card and ext2ls

[javier Martin]

I have an SD card with an ext2 partition and I am trying to access it
through ext2ls command but this is what I get:

# ext2ls mmc 0:1 /
** Bad partition - mmc 0:1 **

I have read some previous mails of some people complaining about a
similar problem:
http://www.mail-archive.com/u-boot at lists.denx.de/msg12776.html

Here also Wolfgang Denk says that ext2 is currently broken in u-boot
for newer ext2 images.

Is this still true or has it been fixed since then?

Thank you.

Also if I issue a "mmc rescan 0" I get the following:

# mmc rescan 0
# ext2ls mmc 0:1 /
get partition info called
raise: Signal # 8 caught
raise: Signal # 8 caught
raise: Signal # 8 caught

What could be happening here?

Thank you.

Looking deeply in the list I found someone that had the same problem
with an AT91:

I submit here all useful information about my case.

Well, that was a long, long time ago. And the problem reported there
(and fixed since) was about newer (bigger) inode sizes - this has
nothing to do with "Bad partition" errors.

> Is this still true or has it been fixed since then?

The problems referred to in the posting you quote have long been
fixed.

Best regards,

Wolfgang Denk

Sorry, the batteries of my crystal ball are running low...

It _might_ help if you provided a _little_ information, at least the
most vital pieces like which architecture / board you are speaking of,
and which exact version (which git commit id) you are running.

Best regards,

Hello,

I rather would say it is broken for rev 0,
i.e. old ext2 images and images generated with genext2fs

> Is this still true or has it been fixed since then?

I just posted a patch: [PATCH] EXT2FS: fix inode size for ext2fs rev#0.

Best regards,

	Michael.

Please see my last mail. I sent three mails without reply and maybe
this lead to some confusion, sorry. In that, my previous mail, you
have all the information: Board, SD card, how to reproduce...

Thank you.
