Pandora Squashfs Pnd Problem

[Hitnrun]

I am for the first time tring to package a big application using squashfs. I am building in Ubuntu 10.4, and passing the "-c" parameter to pnd_make.sh seems to work.

On the Pandora the pnd does not mount, giving this error:

[17989.331756] SQUASHFS error: squashfs_read_data failed to read block 0x224f8b4
[17989.338958] SQUASHFS error: unable to read id index table

I mounted the pnd directly using:

# /usr/pandora/scripts/pnd_run.sh -p tagaini-jisho.pnd -m

But running gives the same error on the .out file.

The file is ~35mb, while the original one is ~85mb.

Does someone saw this problem?

I never had this
all my pnds use squshfs....
are you sure you have the right shashfs tools installed on your ubuntu (4.0) ?

It's what apt-get installed (squashfs-tools).
It says it is using squashfs version 4.0, is this compatible?

As per pnd_make.sh comments, yes : This is the supported version.
Sorry, but I can't see an other reason why this won't mount. And as this isn't your first pnd, I guess the rest(PXML+icon) isn't the problem.
Here are my shots in the dark :
- the FS you're creating these PND is not full ?
- what does say "file tagaini-jisho.pnd" ?
- IO errors in dmesg ? (build host and pandora)
- Copy problem ?

What command should I use to mount a squashfs pnd file on my Ubuntu linux?

 

[Hitnrun]

No the host is not full, and it gives no message in dmesg. I transfer the file via ssh and never got any corruption problems before.

pnd_make command

pnd_make.sh -p tagaini-jisho.pnd -d build -x build/PXML.xml -i build/tagainijisho.png -c

$ ./make_pnd.sh

What command should I use to mount a squashfs pnd file on my Ubuntu linux?

as root (prefix with sudo if requiered) :
mount -t squashfs -oloop tagaini-jisho.pnd directoryName

This looks good. hum, I can't see why this won't mount (and it is not related to filesize too, see kdegames.pnd is 122M, and the debug-build was over 300M...)

 

[Hitnrun]

I will put it somewhere so you can take a look at it.

I've had problems creating my first squashfs PND too. The ISO version is fine, but replacing the -x with -c in the create command returns a PXML related error and the PND doesn't show up on the Pandora. I don't have everything here to give more details, I'll come back to it later.

I had similar problem once while working on Ginge, simply recreating the image fixed it (but burned quite a bit of time to debug this). The image would mount fine but some files were unreadable, what broke Ginge in some subtle ways.

It feels like squashfs-tools on ubuntu are buggy, using uninitialized memory or something and sometimes producing corrupted images.
