HI,
After power short u-boot fails to mount UBIFS and board stuck. Below is a
trace of u-boot

As you can see mount manage to recover partition.
Is where any way to make u-boot to recover UBIFS partition as well?
What else can I do to make my system stable and survive power shorts?

Thanks.

1) Is this an upstream u-boot?

Hi.
1) Is this an upstream u-boot?

Marvell>> version

U-Boot 2011.12 (Jan 08 2012 - 21:53:47)
Marvell-Sheevaplug - eSATA - SD/MMC

GNU ld (GNU Binutils for Debian) 2.22

I will try latest one today.

2) Can you NAND (driver) do subpage writes ?

How can I know it?

Dear Dimax

Thanks for reporting this issue,
I am not UBIFS expert, but I will check this problem at my end.

[U-Boot] UBIFS fails on SheevaPlug

[Dimax]

Tried latest available version for SheevaPlug:

Marvell>> version
U-Boot 2012.04.01 (Jun 01 2012 - 02:27:06)
Marvell-Sheevaplug - eSATA - SD/MMC
gcc (Debian 4.6.3-5) 4.6.3
GNU ld (GNU Binutils for Debian) 2.22

Same result.
Do you know if u-boot has a functionality to recover ubifs partitions?

It should work. AFAIR there is a problem when the malloc arena is to
small. I do currently not know if [1] made it into mainline.
However, can you please check if expanding the CONFIG_SYS_MALLOC_LEN
fixes your problem?

HI,
So you say I have to rebuild u-boot with expanded CONFIG_SYS_MALLOC_LEN.
So far I have used rebuild images from:
http://people.debian.org/~tbm/u-boot/2011.12-3/sheevaplug/u-boot.kwb

I see following files in the parrent directory:

[image: [   ]] u-boot_2012.04.01-2.debian.tar.gz
<http://people.debian.org/%7Etbm/u-boot/2012.04.01-2/u-boot_2012.04.01-2.debian.tar.gz>[image:

<http://people.debian.org/%7Etbm/u-boot/2012.04.01-2/u-boot_2012.04.01.orig.tar.bz2>

Is it all I need to rebuild?
Are there any general instructions?

so if you are using a distributed version of u-boot, why don't file a
bug there?

> Is it all I need to rebuild?

Yes, after increasing the size of malloc arena (supposed my suspicion is
correct).

> Are there any general instructions?

Does <u-boot-src>/README section 'Building the Software' fit your needs?
BEWARE! If you never built u-boot you should know you may brick your
device, see the countless de-bricking guides for sheevaplug and prove
you can de-brick it before you brick it ;)

Hi,
What if I compile a new u-boot but to try it I will load and flash new
created image after original u-boot and will run it from withing original
reboot manually just pointing a new image address? Can it work?

Dear Dimax,

well, you mean to run a u-boot out of a running u-boot?
U-Boot is not designed to do so. But some devices may allow you to just
run a newer u-boot from a running one (at91;). You need to know that
u-boot set up your SDRAM timings which destroys the content of the DRAM.
So if your new u-boot is located there it can not be executed.
I dunno if the kirkwood can do so, but I think they can not. You will need
a) a JTAG
b) another boot device, for example USB, MMC, whichever device the
kirwood SoC can read from its ROM code (I do not know)
to de-brick it.

Please ask some kirkwood specialist or google, there are a lot of
sheevaplug hackers out there, one of them may be able to help you here.

I'm not going to run new-u-boot from RAM. I will flash it. Can I ask
original u-boot to JMP to a flash address and run a new-u-boot from where?

I once debricked SheevaPlug with USB stick. Have to recall how it was done.
But as far as I remember I've found it in the internet so it should be
still where. I understand that I first have to make sure I can debrick my
board before I start playing with u-boot.

I also want to look back at my original problem of non-recovered UBIFS.
Want to make sure my effort will not be useless.
Let's say I've increased the memory allocation size. But are you sure
u-boot implementation of ubifs really can recover partitions just like
original Linux driver does? Is it implemented at all?
If yes I have another doubt. In one forum I've read that u-boot treats
UBIFS partition as read only (while it actually is rw for Linux). And thus
u-boot does not even try to take any action that required writes.
What you think?

well, NAND is no XIP media, you need to move the stuff _always_ from
NAND to RAM to use it.

In fact the u-boot port is copied from linux kernel. It may lack some
newest fixes but in general it has the same features as the linux kernel
has.
The link I posted in my first mail did mention that the error message
for ubifs_get_sb() in ubifs_mount() is useless cause we may have
different root causes here. If your error message had displayed ENOMEM
(or -12) you may have got the root cause by yourself.
However, it may be another reason on your side, looking forward to see
your solution.

thank you for the RFC, but I can not find the TOFU abbreviation in it ;)
However you are right, that should be the pointer for formal correctness.

You will need a JTAG key (amontec on any other) and OpenOCD s/w tool.
Then you can build and test your code on Kirkwood w/o flashing on the device (i.e. running from RAM)

You may look for developer guidelines on the google or plugcomputer forum.

AFAIK, u-boot can't recover your partition. u-boot just mounts it read-only.

[Dimax]

I remember I have unbricked sheevaplug with USB key.
But I'm still not sure if effort is not useless as I see no conclusion
about u-boot ability to recover UBIFS partition (at least to try).
Can anybody tell it for sure?

This is what I've got from the code [1].

Code flow
---------
common/cmd_ubifs.c:
do_ubifs_mount calls ubifs_mount 

fs/ubifs/super.c,
In ubifs_mount()  (line 1167)
	flags = MS_RDONLY;	(line 1188)
calls ubifs_get_sb (with flags as a param)
ubifs_get_sb (line 1018)
The flags get updated here.
	sb->s_flags = flags; (line 1057)

Calls ubifs_fill_super
sb gets assigned, so are the flags.
	c->vfs_sb = sb; (line 962)

Calls mount_ubifs
	mount_ubifs(c); (line 983)

In mount_ubifs() (line 582)

	struct super_block *sb = c->vfs_sb;
	int err, mounted_read_only = (sb->s_flags & MS_RDONLY);

sb taken from the assigned ptr @ line 962.
Flags extracted from the assigned flags @ 1188.
Just see where the variable 'mounter_read_only' gets referred and you'll get the answer.
U-boot will _not_ recover your UBIFS partition like the Linux kernel. CMIIW.

CMIIW.
In other words it is not possible to use UBIFS on embedded Linux boards
with u-boot unless you can provide unterminated power supply.

I'm going to another solution - Split flash in two UBIFS partitions. Make
the first one read only and put kernel and all critical data where. And
have logs and user data on second RW partition. This way kernel should
always start and if required recover second RW partition.

Do you have any suggestions on how to do it or where to start?
More likely I have to look at mtd utilities?

[U-Boot] UBIFS fails on SheevaPlug

[Andreas Bießmann]

Dear Vikram Narayanan,

first of all you are right. u-boot ubifs implementation will never 
recover the ubifs on media, cause it is mounted read only.

calls sget() (line 1043)
which in turn calls kzalloc() (line 67)
which may return -ENOMEM

But u-boot will manage to get the data out of the unordered ubifs (if no 
error like this ENOMEM occur). That is the same process as in kernel if 
it is mounted read-only (recovery deferred).
So if the kernel can manage to mount the unordered ubifs u-boot should 
do so. If it can't (but the kernel can) there is an error that should be 
fixed.

I agree. But in Dimax's case this isn't. Right?

I can't comment on this, unless I know the specifics.

But in the kernel, the read-only isn't hardcoded. So, the kernel code 
can try to recover and even update the corrupted data back to the media 
and mount it. (It's my guess. The kernel may/mayn't do this way).

But if the same fails to happen in u-boot code, I'd say the feature is 
missing and it needs to be pulled in from the kernel code.

Vikram

I dunno cause he has an old version which do not print the error code
(patch f75325e1927398f7e18e15f186b1fc52174cc19f is missing).

>> But u-boot will manage to get the data out of the unordered ubifs (if no

Please read mount_ubifs() in fs/ubifs/super.c:582

Even if it is mounted read only and recovery is needed it will
ubifs_lpt_init(), ubifs_replay_journal(), ubifs_mount_orphans(), ...
If recovery is needed it will ubifs_recover_size() and if it is mounted
read only it will print at last 'recovery deferred' (in the other case
it would be still repaired here cause the steps before do it).
So at least a read only fs which needs recovery can be successfully
mounted (if no other error occurs; the most likely error is a ENOMEM
cause the ubifs does a lot of k(z)alloc).

Well bootargs can have 'ro' so the root partition will be mounted read
only, wouldn't it? Wouldn't this 'ro' root partition not mounted by the
kernel then?

Thanks. I'll look at this.

Got your point here. Then no feature could be claimed as 'missing' in 
the u-boot's ubifs compared to the kernel's, except for the well known 
fact that u-boot's ubi layer is old code.

HI guys.
I'm sorry I had other jobs to do and did not have time to dig it.
I have tried SheevaPlug port from
http://people.debian.org/~tbm/u-boot/2012.04.01-2/
and it fails and gave me no error code. Not sure it is because of old
version or error just did not happen.

I still keep a box with broken ubifs to try new u-boot on it.
Is where any chance someone will help me to build a latest u-boot port for
SheevaPlug?
Actually someone is doing it. I took latest version here:
http://people.debian.org/~tbm/u-boot/2012.04.01-2/

Also can you tell me if this version has error printing patch or not?

well as said before, if the <u-boot-src>/README (section 'Building the
Software') does not help you I could answer concrete questions.

So maybe can you ping Martin Michlmayr to release a new version?

Presumably not, it is in v2012.10.

[U-Boot] How to enable debug information in u-boot

[Paulo Louro]

Hello all,
Is there any ways to activate more debugging information during SPL and u-boot process?
I?m trying to boot u-boot for the Hackberry using Henrik source code but im only getting the following via serial console:
U-Boot SPL 2012.10-04714-gc9a957f-dirty (Oct 31 2012 - 20:30:47)Board: sunxi

[U-Boot] UBIFS fails on SheevaPlug

[Dimax]

Well so far no luck,
Actually I'm not sure how to start. But I will try to go on "with a little
help from my friends".

I)
The first question that raised is a compiler. I see two options:
1. Use the cross compiler - this is what more likely most of the people are
doing.
2. I wonder if I can use native compiler? I actually have a number of
running SheevaPlugs with gcc installed on them.
Do you think it will work?

II)
After extracting files I have following tree:

u-boot_2012.04.01-2_armel.deb
debian:
   README.Debian
   control
   env-configs/
   manpages/
   rules*
   targets
   changelog
   copyright
   lintian.overrides
   patches/
   source/
   watch
u-boot-2012.04.01

According to README all I have to do is to run
make NAME_config
The sheevaplug is listed in boards.cfg so there should be no problem to
make sheevaplug_config.

In this case I do not get what are the other two directory and file:
u-boot_2012.04.01-2_armel.deb
debian/

To my understanding debian/ is some port but I do not see any makefile
where. So not sure hot to use it?

Both should work, if you need an cross compiler have a look at ELDK [1]

Wrong file! Please use the source from denx.de, either git from
git://git.denx.de/u-boot.git or a released version from
ftp://ftp.denx.de/pub/u-boot

Thats true for native build (never tested, may not work)

You will need some compiler flags:
 CROSS_COMPILE (prefix for 'gcc' when cross compiling)
 PATH (should contain your toolchain)

I would build it that way:

Well, that is a pre-compiled debian package for armel. The debian
directory contains some information for the debian package system.

You don't need a git for it. Mail access should be fine.

Find the below mail in your inbox and reply to that,
