Sorry for the resend, seems my gmail editor was in HTML mode which got
rejected by the mailing list.  Humble apologies.

I have run into an issue with the Atmel nand controller on the
SAMA5D36, which I am struggling to debug.

We are using custom hardware based on the SAMA5D36. With Micron
MT29F8G08ABBCAH4 NAND flash.  Kernel version is 4.14.29 - mainline
from kernel.org.  ECC strength is 24 bits with 1024 byte sector size.
The PMECC settings was calculated as per
https://www.at91.com/linux4sam/bin/view/Linux4SAM/PmeccConfigure, with
the nand HEADER value at 0xc0e18e05.

The system works, and only some units present the error, the baffling
part of it, is that a unit can work properly for a long while, and
then suddenly the error presents itself. (Once traced it to a glibc
library file, which means it isn't even due to heavy writing on the
filesystem.) I have noticed that most of the time the PEB in which the
error occurs is the same.  Even after reprogramming the device via
ubiformat, or SAM-BA.

In the attached log output, you will see that there is a UBIFS error,
where it detects a bitflip, which I confirmed by comparing the binary
sequence to the Buildroot generated ubi file.

Using Atmel's SAM-BA to read back the contents of the NAND flash,
yields the correct contents for the page causing the ECC error.

31 18 10 06 00 FE A2 74 FB CF 00 00 00 00 00 00 C5 05 00 00 01 00 00
00 AB 0C 00 00

Starting up linux again results in the same issue.
This extract shows the ubifs magic number with the bitflip. The rest
of the binary sequence matches a unique part of the ubi image.

            };

Attached are the dmesg traces with the ECC issue.  A nanddump of the
block with the ECC error, including OOB contents as per "nanddump -f
nandblock-withoob.ubi /dev/mtd5 -s 0x51c0000 -o -l 262144 &>
nanddump-cmdline-output.txt"

I am almost constantly banging my head against a metaphorical wall on
this one.  Any help in solving it will be much appreciated.
