Hi,

I have been troubleshooting some CAN problems on our imx6ull with a raw 
nand flash.
I normally run with a 4.19 series kernel, but to verify those CAN 
problems have been resolved in newer kernels i have been trying ~5.3-rc6.

But with that kernel i have run into trouble with ubifs, it throws a lot 
of errors:
[  188.384572] Not a node, first 24 bytes:
[  188.384588] 00000000: ff ff ff 00 00 00 00 e4 03 00 00 a0 81 00 00 01

[  188.411605] UBIFS error (ubi0:8 pid 117): ubifs_read_node: bad node 
at LEB 46:49888, LEB mapping status 1

I started a bisect from Linux 5.3-rc7 (bad) to 5.2 (good).
And i'm ending up here:

What kind of CAN problem? (Cc += linux-can).

Sascha has Maintainer Duties on his todo for today anyways.

4k page size NAND, I didn't have such a device for testing, so indeed it
could be that my patch is broken for 4k NANDs.

I assume your device had a bbt before, right? In that case we won't have
to go down to UBI, even a plain read seems to be broken.

Could you dump some NAND page with and without ef347c0cfd619a and see if
and how they are different? Something like "nanddump -c -l 4096 /dev/mtdx"
should do it. Maybe you have to adjust the starting address with the -s
option to get some page with data.

Also you could try the mtd test modules to see if tests fail.

Yes my devicetree looks like this:
&gpmi {
         pinctrl-names = "default";
         pinctrl-0 = <&pinctrl_gpmi_nand1>; 
 
 
 

         nand-on-flash-bbt;
         status = "okay";
};

Is is better to dump them to gist?

With mtd0 you took the blocks containing the bootloader. Try the one on
which the UBI volume is. Also please pick a page that is almost full.

You could generate a page with this (on the working kernel preferably):

flash_erase /dev/mtd2 0 0
seq 2000 | dd bs=4096 count=1 | nandwrite /dev/mtd2 -

Note this will erase /dev/mtd2

did the commands decribed above ^^

root@iwg26:~# /tmp/nanddump -c -l 4096 /dev/mtd2
ECC failed: 0
ECC corrected: 0
Number of bad blocks: 0
Number of bbt blocks: 4
Block size 262144, page size 4096, OOB size 128
Dumping data starting at 0x00000000 and ending at 0x00001000...

What about this "Bad block table written" message? You should see this
exactly once. Do you see this multiple times, especially when switching
kernels between the good one and the bad one?

Not exactly sure what you mean, but here is the dumps:

The Bad block table is written once. When you see this message multiple
times then this means that Linux can't read the BBT and writes it again.
So the question is: Start the good kernel multiple times. Do you see
this message once or on each boot? Then start the bad Kernel multiple
times. Do you see the message once or on each boot?

Yes, that's normal. The BBT itself is marked as bad. Otherwise the they
would just be used by regular mtd users.

And is this the bad kernel or the good kernel? The question I am trying
to answer is: Can the good kernel read the BBT it has written? Can the
bad Kernel do that?

Exactly the same output... which must mean it fails reading/writing the

Hi Sascha

Please let me know when you have some time to look into this :-)
I dosen't seem right that it writes the bbt on a 4.19 series kernel twice

Writing the BBT twice is expected.

Hi,

Seems like it's U-boot that is corrupting the table.

I don't think that U-Boot is corrupting the table. Apparently
ef347c0cfd619a925 introduces a unwanted change in the page layout of the
NAND. I would expect that with the known good kernel you have a bbt
written by either the Kernel or U-Boot, doesn't matter, both parties can
read it. Once you start the broken Kernel the kernel can no longer read
the table, re-writes it, can now read it itself, but U-Boot no longer
can read it, then re-writes it with the effect that Linux re-writes it
again.

I don't know how the differences look, you have to nail that down
yourself by systematically using nandwrite and nandread, maybe with or
without oob. Once you found the differences I can help you in finding
the issue in my patch. Alternatively I can offer you to have a look
myself, but you would have to provide me a board, either physically
by mail or virtually by ssh.

We are using suspend (to ram).
And it seems that it's suspend that triggers the UBI errors.

I'm getting this in the log:
