ENE KB9012QF A3 reflash help needed

[Nyúlós Lónyál]

Hi!

I'm trying to flash an ENE KB9012QF A3 KBC on LA-8241P motherboard. The
problem is flashrom can't detect the internal SPI of it, fails with error.

flashrom p1.0-141-g9cecc7e on Linux 4.15.0-20-generic (x86_64)
flashrom is free software, get the source code at https://flashrom.org

flashrom was built with libpci 3.5.2, GCC 7.3.0, little endian
Command line (5 args): ./flashrom -p rayer_spi -c KB9012 (EDI) -V
Using clock_gettime for delay loops (clk_id: 1, resolution: 1ns).
Initializing rayer_spi programmer
Using address 0x378 as I/O base for parallel port access.
Using RayeR SPIPGM pinout.
The following protocols are supported: SPI.
Probing for ENE KB9012 (EDI), 128 kB: edi_chip_probe: reading hwversion
failed
No EEPROM/flash device found.
Note: flashrom can never write if the flash chip isn't found automatically.

How to get it working? Thanks a lot for help!

Hi Nyulos,
Have you tried following the KB9012 flashing instructions at
DangerousPrototypes wiki?
http://dangerousprototypes.com/docs/Flashing_KB9012_with_Bus_Pirate
Although that is for Bus Pirate / CH341A programmers and LA-A091P,
should be similar for your Rayer programmer and LA-8241P motherboard.
Most importantly, before plugging the power adapter you should unite
three grounds:
1) GND of laptop's motherboard
2) GND of your programmer
3) GND of KB9012
Best regards,
Mike Banon

I think he's trying to use an internal SPI (maybe he should try "-p 
internal_spi" instead of "-p rayer_spi"?), so tying grounds probably 
won't help for that? He might have to use an external programmer 
instead, so he'd want to tie grounds then!

[Mike Banon]

This rayer_spi is "RayeR parallel port programmer" which is external.
Internal flashing will not work until someone will reverse engineer
the proprietary UEFI update mechanism part of updating EC firmware.

P.S. Meanwhile I'm contributing various patches to coreboot,
although they are not discrete GPU-related yet (sorry I'm such a slowpoke!)
you may want to take a look, e.g. some of them are for ACPI S3 inspired by HJK

Hi Mike!

I've followed the linked guide, it gave me these results. The grounds are
united, still the same error happens. I have tried to GND pin 42 of KB9012
as mentioned in the guide, and tried to connect both pin 41 and 42 to GND,
as in KBC's datasheet at EDI related part, still no success, flashrom
doesn't detect it.

Just to double-check: please discharge the motherboard completely by
trying to turn it on while there is no power adapter connected, then
unite three grounds (KB9012 / programmer / motherboard ) and only then
connect the board's power adapter . After doing all that, please check
if you could read it now. Also, what if your issues are programmer
related? Is it possible for you to try another programmer, like CH341A
? (because it costs like $2-$3 with free shipping from china, just
prefer to get a green PCB version because there were some 3.3/5V
issues with some black PCB CH341A , and blue PCB version costs the
same low price while having fewer pins) Or maybe you could get it
locally for a (hopefully) small premium if you're in hurry

Yea, tried to discharge the motherboard, taken out CMOS battery too, it
didn't help. I don't know if this is programmer related or not, I have
reflashed 2 types of BIOS SPI chips with it, EN25QH16 and W25Q32BV. But
these chips are maybe different from KB9012's debug interface. I can't get
a CH341A for now, maybe some months later. It would be good to recover the
laptop if it's possible with the tools I have currently, but not very
urgent. Here is the programmer's config, if it helps:

Finally managed it to detect KBC's internal flash using the motherboard's
BIOS socket with removing it's SPI chip after boot, and connecting KB9012
in there. But the read always gives me different files, so I can't backup
the current content of KB9012.

[Mike Banon]

That is because KB9012 is active after your laptop has booted and not
in debug state where it is possible to reflash it without a problem.

Have you double checked your laptop's datasheet to make sure your
connection is correct, and also that your laptop's corner ground is
really connected to its' ground? (what if not all its' copper circles
are the grounds in your case)

[Nyúlós Lónyál]

Sorry for the confusion. :( I think you have misunderstood me.

My laptop's motherboard is taken out of the laptop. I have another machine,
a desktop PC which I've used for trying rayer_spi programmer. Now I connect
the laptop's KB9012's debug pins into the desktop PC motherboard's DIP8
BIOS socket with wires, after it booted the linux distribution with
flashrom installed and removing it's original BIOS SPI chip. The two
machine's GND, DIP8 socket's GND, and KB9012's pin 42 are united.

Like when recovering a regular motherboard BIOS with hot-swapping chips,
just the only difference I connect the laptop's KBC instead of another BIOS
chip: https://www.coreboot.org/FAQ#Developers

I think the desktop motherboard's BIOS socket can be used as an SPI
programmer this way, originally it has W25Q80BVAIG DIP8 chip which can be
removed. That gave me these results, read and write errors which I sent
before, but at least it can detect KB9012. I've tested with the original
BIOS chip, flashrom can read, erase, and write it. The motherboard is an
Asrock G41C-GS first generation, rev 1.0.2.

The laptop can't boot, doesn't even react to power button or recovery key
combination, and no charging LED lighting up, since it got bricked with a
wrong BIOS update, this is why I want to reflash KB9012 with an external
tool, like the desktop PC motherboard's DIP8 socket.

Sorry if I've already asked this question, but how long are your
wires? Ideally they should be about 10cm length and made of good
copper. Although it could work even for 30cm poor aluminum wires,
still when there are read/write errors - the first suggestion which
comes to my mind is to shorten the wires. I understand that it could
be difficult to use short wires at your flashing setup, but hope it is
possible for you to try. And also I hope that you've ordered CH341A
just in case our suggestions wouldn't work.
> The laptop can't boot, doesn't even react to power button or recovery key combination, and no charging LED lighting up

Everything from this list is expected if there is a corrupted KB9012
firmware, because it is KB9012 which listens for your power button
keypresses / controls the LEDs / etc

The two machine's GND, DIP8 socket's GND, and KB9012's pin 42 are united.

That gave me these results, read and write errors which I sent before, but at least it can detect KB9012. I've tested with the original BIOS chip, flashrom can read, erase, and write it. The motherboard is an Asrock G41C-GS first generation, rev 1.0.2.

I don't know if this is programmer related or not, I have reflashed 2 types of BIOS SPI chips with it, EN25QH16 and W25Q32BV. But these chips are maybe different from KB9012's debug interface.

The wires are ~20-25cm made of aluminium, but I have some broken USB cables
with copper wires. I can reduce the distance of laptop's keyboard connector
and DIP8 socket to about 5cm wire length, will give it a try tomorrow. And
something that I've noticed at verifying with flashrom, it always gives a
random hex number after "failed byte count from 0x00000000-0x0001ffff".
Maybe the "Timed out waiting for SPI not busy!" error is caused by the
wires too. Thanks for the idea, I will reply back with results.

Same problem with 5cm long copper wires. Here is a video of what's

Sorry for a long reply, I just watched your video and - unless you
changed its' speed - it seems to me that your KB9012 operations are
going faster than expected, e.g. it reached 0x4*** address almost
instantly while in my CH341A case it was almost certainly slower. So
maybe you could experiment with spispeed parameter, like flashrom -p
internal:spispeed=frequency , please look it up online ( I can't at
the moment )

I can reduce the distance of laptop's keyboard connector and DIP8 socket to about 5cm wire length, will give it a try tomorrow. And something that I've noticed at verifying with flashrom, it always gives a random hex number after "failed byte count from 0x00000000-0x0001ffff". Maybe the "Timed out waiting for SPI not busy!" error is caused by the wires too. Thanks for the idea, I will reply back with results.

Now I connect the laptop's KB9012's debug pins into the desktop PC motherboard's DIP8 BIOS socket with wires, after it booted the linux distribution with flashrom installed and removing it's original BIOS SPI chip. The two machine's GND, DIP8 socket's GND, and KB9012's pin 42 are united.

That gave me these results, read and write errors which I sent before, but at least it can detect KB9012. I've tested with the original BIOS chip, flashrom can read, erase, and write it.

I don't know if this is programmer related or not, I have reflashed 2 types of BIOS SPI chips with it, EN25QH16 and W25Q32BV. But these chips are maybe different from KB9012's debug interface. I can't get a CH341A for now, maybe some months later. It would be good to recover the laptop if it's possible with the tools I have currently, but not very urgent. Here is the programmer's config, if it helps: https://github.com/flashrom/flashrom/blob/master/rayer_spi.c

I have tried to GND pin 42 of KB9012 as mentioned in the guide, and tried to connect both pin 41 and 42 to GND, as in KBC's datasheet at EDI related part, still no success, flashrom doesn't detect it.

[Nyúlós Lónyál]

Thanks for replying at my noob questions. :) The spispeed parameter, yea, I
thought about it after looking into flashrom's source on GitHub. Sadly it's
not in the code of ICH7 chipset (ichspi.c), so the spispeed option in
flashrom command is unavailable. Someone already did that for AMD SB600
chipset (sb600spi.c), found a link about it:
https://mail.coreboot.org/pipermail/flashrom/2013-August/011410.html

I don't know much about C programming language, so I can't transform that
code for ICH7. I have no more ideas, maybe it's possible to modify the
default SPI frequency in ichspi.c, I'm not sure.

[Mike Banon]

Maybe try inserting some extra programmer_delay(n) to your ichspi.c ?
Also I had a patch for the unreliable flashing environments -
https://review.coreboot.org/c/flashrom/+/23840 - but didn't improve it
yet so it haven't been merged, and already incompatible with the
latest flashrom. Also maybe it doesn't affect KB9012 if its' flashing
functions are different, but maybe it could be useful somehow. Still I
hope that you've already ordered that CH341A since it costs very
cheap, just $2-$3, and could save a lot of your time.

I can reduce the distance of laptop's keyboard connector and DIP8 socket to about 5cm wire length, will give it a try tomorrow. And something that I've noticed at verifying with flashrom, it always gives a random hex number after "failed byte count from 0x00000000-0x0001ffff". Maybe the "Timed out waiting for SPI not busy!" error is caused by the wires too. Thanks for the idea, I will reply back with results.

Now I connect the laptop's KB9012's debug pins into the desktop PC motherboard's DIP8 BIOS socket with wires, after it booted the linux distribution with flashrom installed and removing it's original BIOS SPI chip. The two machine's GND, DIP8 socket's GND, and KB9012's pin 42 are united.

That gave me these results, read and write errors which I sent before, but at least it can detect KB9012. I've tested with the original BIOS chip, flashrom can read, erase, and write it. The motherboard is an Asrock G41C-GS first generation, rev 1.0.2.

[Nyúlós Lónyál]

There are some programmer_delay values in ichspi.c, here is one which says
something about frequency:

timeout = 100 * 60; /* 60 ms are 9.6 million cycles at 16 MHz. */
while ((REGREAD16(ICH7_REG_SPIS) & SPIS_SCIP) && --timeout) {
programmer_delay(10);

So I just need to increase programmer_delay, for example to 20 and maybe
the timeout to 200 * 60?

I can try another method too as the KB9012 datasheet says "To enable EDI,
it is by detecting any SPI command with EDI_CLK frequency between 1MHz to 8
MHz.", so maybe after probing with flashrom in DIP8 socket, and connecting
it to rayer_spi LPT it will detect and flash KB9012 correctly with lower
SPI frequency.

And yes, I know getting a CH341A would be the easiest way to solve my
problem, but I'm currently not at home, so I should wait with it for some
months, that's a long story. :/ I'm just trying what I can do to spend the
waiting time useful and maybe as result with solving this earlier.

no, this has nothing to do with the transmission speed, it's really just
a polling loop with a timeout. Generally, the ichspi (both hardware and
driver) expect a perfect connection to the SPI slave... plus the hard-
ware might make assumptions about the type of commands used. It's not
meant to work with your setup, so you need a lot of luck.

According to its datasheet the ICH7 runs its SPI clock at 17.9MHz. It's
not completely hopeless, though.

Sounds like a fragile procedure, make sure that you never have the ICH
and Rayer connected at the same time. Also, what Mike said about the
wire length applies to your setup with the Rayer, too.

Hi Nico!

Thanks for explaining. :) So what can I do in this case? Which programmer
is the easiest to get the setup working? Rayer_SPI didn't even detect it,
nor with shorter wires, this is why I went to ICH7, at least it can
recognize KB9012, and read some random data from it. I will not connect
both programmers at the same time, but I have a theory Rayer_SPI doesn't
give SPI clock signal continuously, thus KB9012 didn't enter EDI mode.
