NAND ECC on Marvell Armada SoC

[Steve deRosier]

Hi All,

I'm working on a platform I haven't worked on before and I'm getting
some conflicting readings from the hardware and having trouble getting
UBI-based images to run correctly and I was hoping someone here might
have some experience that can point me the right direction.

Before going into the details, here's my questions:

* Does this controller store the ECC bits somewhere other than the OOB
in the flash?
* Is it possible/likely for the vendor to have modified u-boot to not
tell me the ECC bits in the OOB?  Or a u-boot bug on this platform
where it would've not shown the OOB?
* Is there a way to force a particular ECC configuration (including
disabled) for this driver via the DTS and have it ignore the ONFI
configuration? (I figure I could explore different configurations
until I got something that matched).


The device is running a MV88F6820 SoC, with the NFC running via the
pxa3xx-nand driver. I've got two versions of the hardware, one with a
AMD/Spansion S34ML02G2 SLC NAND (let's call this Unit1), the other
with a  Winbond W29N02GV SLC NAND (Unit2). The platform is a
third-party platform. I'm running OpenWRT/LEDE on it.

When I tried to replace the stock images on Unit2, either with stock
LEDE or my own built OpenWRT images, it would boot the kernel and then
UBI would spew ECC errors, resulting in an eventual rootfs not found
panic. I don't think it's terribly interesting, but if you want to see
the exact errors, I've attached the relevant chunk as a text file.
Note that I was able to try flashing from both a running system as
well as from u-boot with similar results.

On Unit2 I was able to get it to boot via an initramfs, ignoring the
UBI errors, so later information about a running Unit2 refers to this
configuration.

With Unit1, we were able to upgrade the stock image to a stock LEDE
and it booted just fine.

My operating theory is that something's fishy with the flash ECC setup
on Unit2. It's notable that the stock images (kernel 3.10.70) are
unable to recognize the Windbond flash and have this:
    [    1.967295] armada-nand f10d0000.nand: Initialize HAL based NFC
in 8bit mode with DMA Disabled using BCH 4bit ECC
    [    1.981683] NAND device: Manufacturer ID: 0xef, Chip ID: 0xda
(Unknown NAND 256MiB 3,3V 8-bit), 256MiB, page size: 2048, OOB size:
64

With the LEDE images (kernel  4.9.82) on Unit2, do recognize the flash chip:
    [    1.041804] nand: device found, Manufacturer ID: 0xef, Chip ID: 0xda
    [    1.048181] nand: Winbond W29N02GV
    [    1.051604] nand: 256 MiB, SLC, erase size: 128 KiB, page size:
2048, OOB size: 64
    [    1.059204] pxa3xx-nand f10d0000.flash: ECC strength 1, ECC step size 512

And on Unit1 which is working fine, and which seems to be the original
hardware rev, and running a 4.4.92 kernel:
    [    1.008510] nand: device found, Manufacturer ID: 0x01, Chip ID: 0xda
    [    1.014899] nand: AMD/Spansion S34ML02G2
    [    1.018836] nand: 256 MiB, SLC, erase size: 128 KiB, page size:
2048, OOB size: 128
    [    1.026527] pxa3xx-nand f10d0000.flash: ECC strength 16, ECC
step size 2048

It's also interesting to note the U-Boot versions are different on the
two different hardware revisions.

My usual debugging for this sort of thing involves looking at the ECC
bits in the OOB. This is where things seriously diverge from my
expectations. In all cases, a u-boot `nand dump 0x...` results in
showing OOB data of 0xff.  On Unit1, on the Linux command-line, a
`nanddump -o -c ` shows no data in the OOB in any mtd device. On
Unit2, once I was able to boot it via an initramfs, it does show data
in the OOB in the kernel and rootfs areas that I flashed (but none in
the boot partitions).

What I strongly suspect is u-boot is defaulting to a particular ECC
configuration and writing the OOB in a particular way, in a way that
is in conflict with the ECC configuration the kernel is using because
the newer kernel is choosing to configure based on the ONFI
parameters. Also, at first I suspected that u-boot wasn't writing any
ECC data because it didn't recognize the chip and the `nand dump `
commands were showing erased OOBs.

On another platform (an Atmel) with kernel 3.8, if the OOB was blank,
the NAND driver would ignore ECC errors. I understand that's no longer
the case in more current kernels, and might not be the case with the
pxa3xx-nand driver anyway, but if it is that way on 3.10, it could
explain why the manufacturer could have changed the flash, U-boot
would write no ECC, and the system would boot fine; but with the
upgraded kernel the system drops ECC errors on the UBIFS rootfs mount.

I don't know this platform very well yet, nor do I have full control
over it yet, so any hints by someone who does know this NFC and driver
would be helpful.  Here's the first handful of questions I have:

* Does this controller store the ECC bits somewhere other than the OOB
in the flash?
* Is it possible/likely for the vendor to have modified u-boot to not
tell me the ECC bits in the OOB?  Or a u-boot bug on this platform
where it would've not shown the OOB?
* Is there a way to force a particular ECC configuration (including
disabled) for this driver via the DTS and have it ignore the ONFI
configuration? (I figure I could explore different configurations
until I got something that matched).
* Does anyone have any other ideas?

Thanks,
- Steve
