UBI FS on 2MiB eraseblock Hynix MLC NAND

UBI FS on 2MiB eraseblock Hynix MLC NAND

[Viktar Palstsiuk]

Hello,

While trying to use UBI FS on Hynix MLC NAND (2MiB eraseblock, 8k
pagesize) I faced with the problem that root mounts well only during
first boot after it was flashed.
On the second boot it reports that it failed to recover master node.
If some one has tested UBI FS on devices with large eraseblock?

Well, in theory it should work, but I've never heard about such huge
eraseblock so probably you are the first trying it, and probably there
is a bug.

Could you please enable UBIFS debugging, reproduce the issue and send me
all the kernel output - e.g., by typing dmesg or booting with the
ignore_loglevel kernel option?

Re: UBI FS on 2MiB eraseblock Hynix MLC NAND

The problem was caused by behavior of H27UBG8T2ATR Hynix MLC NAND
while UBI FS was trying to do page write operation. UBI FS was trying
to write data to the first empty page assuming that 0xFF page is
erased and writable. But this type of NAND returns error on page write
operation even if it was entirely written with 0xFF before. As far as
I'm using U-boot's 'nand write' to flash UBI image I've added skip if
U-boot trying to write 0xFF-page.

So it works fine now.

I also had to increase PEB size limit in mtd-utils to create UBI image.

This solution is not acceptable as we are currently discussing in the
"GPMI-NAND Status" thread in this mailing list.

Instead, you should just change u-boot, and I believe someone has done
this recently - ask the u-boot mailing list. I think that was Ben -
CCed.

The alternative is to use the new UBIFS "fixup" feature, see
http://www.linux-mtd.infradead.org/faq/ubifs.html#L_free_space_fixup

Additionally, here is my old writing about how the UBI flasher should
work, just FYI:
http://www.linux-mtd.infradead.org/doc/ubi.html#L_flasher_algo

> So it works fine now.

No, with this change if my data happens to be all 0xFFs - it will be unprotected
against bit flips.

BTW, I asumme you read this:

Please, introduce a nice macro like MAX_PEB_SIZE and use it instead

Yep. That was me (with some critical help from others of course).

The problem to which you (Viktar) are refferring is certainly not
limited to hynix, 2mib or mlc. I agree with Artem's assessment: use
the new 'nand write.trimffs'  command in u-boot or use the fixup flag
in your ubi images.
