Hi David,
Lewisburg PCH defines sixty SPI region
Hi David,
Lewisburg PCH defines sixty SPI regions, but from the code in ichspi.c, I
find it defines only 10 regions, is this the reason about only 10 regions
was described in the log file?
code as below: (num_freg define the spi regions)
int ich_init_spi(void *spibar, enum ich_chipset ich_gen)

Hi David,
About set permissions for the "BIOS" master via BRWA and BRRA in the FRACC
register, do you mean modify the below location by FITC.exe? if yes, I have
changed the "Host CPU/BIOS Write Access" & "Host CPU/BIOS Read Access"'s value
to 0x to enable all the sixty region's access, but the

Hi Sandy,
That range is outside of what you have defined in your flash descriptor.
Can you update your flash descriptor to include it?

Hi David,
I have used your program to verify, but it still can't flash, it prompts
"Transaction error between offset 0x00ff and 0x00ff003f (= 0x00ff003f
+ 63)"!

Hi Sandy,
Recent Intel PCHs use hardware sequencing which abstracts a lot of details
about the chip. So we don't actually need flashrom to explicitly support
the W25Q256.
Here is a tarball based on the latest sources from git:
https://drive.google.com/file/d/0Bz3WBh8gVeIuSlJYZ2c1bS1LdGc/view?usp=s
Hi David,
I have get the package from the web, but I can't find the code about
"25Q256" in flashchip.c, so, maybe this will lead to flash fail.

Hi David,
Yes, My system's ISA/LPC vendor id and device id is 8086:a1c6,
In fact, I can't access the clone https://review.coreboot.org/flashrom.git,
I attempt to add the patch to flashrom-0.9.9, but I found the difference
is a bit big between these files, I'm very hard to add the
patch completely
Hi Sandy,
What is the result of `lspci -nn | grep ISA` on your system? I uploaded a
patch for Lewisburg PCI IDs here: https://review.coreboot.org/#/c/20922/
I have tested Lewisburg PCH + W25Q256xxx and it seems to work. Let me know
if you need any help applying the patch and testing it out on your
Hi David,
Do you know whether the configuration "Lewisburg PCH + W25Q256xxx SPI" has
been tested with the flashrom? thank you!

Hi Sandy,
Correct - The PCH will not allow us to write anything to regions which are
not defined in the flash descriptor. You could add those regions to the
"BIOS" region if you wish to update them from your host OS. The SPI
Programming Guide for your PCH (Lewisburg?) should also have info about
ad
Hi David,
It seems that the below 2 regions are "write denied":
00A26000 00A35FFF 0001DER #1 Region
00A36000 00FE 005BA00010 Gbe A Region
By the way, can you tell me what is the other parament "EW", "S" and "E"
meana? thank you!
2017-08-07 13:02 GM
Hi Sandy,
It might not have done what you expect. The error is because offsets
0xa26000-0xff are not defined in the flash descriptor, so the PCH gives
us an error when flashrom attempts to update it. ":WD" next to the offsets
in the log means "write denied".
If you wish to update that region o
Hi David,
Thank you very much, I will try to add the patch to flashrom-0.9.9, As a
BIOS engineer, it is a bit difficult for me to complete this.
Do you know when will make it into a release tarball?

Hi Sandy,
Skylake support was recently merged: https://review.coreboot.org/18973
However you may need to add your PCH PCI ID. What does `lspci -nn | grep
LPC` show on your test system?
And yes, a 32MB ROM should work fine.
