Hi all,
I'm having problems with the flashrom on my system. I'm trying to read out the rom content from my machine which is a hp machine with ich9 controller and Amtel AT26DF321 flash chip. However, the reading only halfway through and error occur. Anyone encountered this? Can provide some advice on this?
Thanks.
Attached is the error output:

I can only tell the reason. Your current BIOS prevents flashrom from reading certain part of the flash chip. I don't know if there is any way to bypass that setting.
If you are interested in further explanation on the flashrom output, please read on.

Error occurs here, when flashrom tries to read data at offset 45056 from the flash chip. 45056(dec) = b000(hex).
Look at FREG2.
0x5C: 0x023f000b (FREG2)
The value 0x0(23f)0(00b) means, the area in the flash chip from 0x00(00b)000 to 0x00(23f)fff belongs to (F)lash (REG)ion (2), which stores data for the "Management Engine". That is, flashrom runs into error when it is trying to read FREG2.
Now look at FRAP.
0x50: 0x00001a1b (FRAP)
The least significant byte '1b' indicates which regions software can read. Expand it to binary, 00011011. That means the software can read FREG0, FREG1, FREG3 and FREG4 but not FREG2. That is why flashrom runs into error at offset 45056.

Yu Ning, thank you for the very enlightening explanation! I wonder what the following means (on my machine): 0x54: 0x00000000 (FREG0)
Flash region of size 0? BTW: 0x50: 0x00000a0b (FRAP)
Andriy Gapon wrote:

All 0s value is confusing at the first sight. However, if you would like to read the explanation once more and pay attention to the detail, I believe you will get a different conclusion.
The value 0x0(23f)0(00b) means, ... ... to 0x00(23f)fff ...
You probably have got it.
The explanation contains minor error, though. To be exact, bits 28 .. 16 of FREGn represent bits 24 .. 12 of the region's limit. That is one bit more than my parentheses show. Bits 11 .. 0 of the region's limit, I believe, is 0xfff, which is not clearly stated in the datasheet. Bits 12 .. 0 of FREGn represent bits 24 .. 12 of the region's base. The other (lower) bits of the region's base should be 0.
Therefore, 0x00000000 should mean a region from 0x0000000 to 0x0000fff.
BTW: 0x50: 0x00000a0b (FRAP)
According to the datasheet, the bit n in bits 7 .. 0 indicates software read access to FREGn (n is in [0, 4]). Similarly, the bit n in bits 15 .. 8 indicates software write access to FREG(n-8) ((n-8) is in [0, 4]). So the value means software can write to FREG1 and FREG3, while it can read FREG0, 1 and 3. However, iirc, there is other protection mechanism, so software may still be banned to write on part of FREG1 or FREG3.
If you would like to get information from the source, dig into Chap 22 of the ICH9 datasheet. You may need multiple parses to find out what you need. Besides, there are some mistakes in the datasheet, but that should not affect if you are not reading it very carefully.

Yu Ning, thank you very much again. BTW, an unrelated question:
Generating OPCODES... done
does this line mean that no opcodes at all were generated? I wonder why that could be.

You are welcome.

I think it means opcodes have been successfully generated. The difference you saw may be caused by changed printing code in different versions/revisions. I am not following the recent commit (v0.9) closely, so not sure of that. However, I think you can find it out easily. Just look at the gen_opcodes (maybe not exactly that name) function in ichspi.c

Hi,
Thanks for the explanation. After looking at the ICH9 specification, i'm thinking of modifying the FRAP register value in order to enable write and read permission to all the region. However, i have a question:
How to exactly use flashrom to bring the SPI into descriptor mode so that i can do a read and write to FRAP? Or is that even possible?
Thanks.

I am afraid that it could not be done if datasheet is correct.
As you may have read in the datasheet, FRAP in the chipset is a shadowing register, it is read-only. The original data is in region 0(flash descriptor) of the flash chip, being read during chipset initialization. Since region 0 is also write-protected, flashrom cannot change it. That is a cycle.
How to exactly use flashrom to bring the SPI into descriptor mode so that i can do a read and write to FRAP?
I have some words here because I think you might misunderstand something.
The SPI controller sets itself in descriptor mode when it sees some mark in the flash chip during initialization. It does not need flashrom to bring it into d-mode. And as a memory-mapped register, FRAP can be read regardless of the mode it is in.

Hi,
Thanks for the guidance.
Not sure if Is there any more useful documentation beside the datasheet of the ICH9 that i can refer to to read more about SPI chip programming?
Thanks.

Don't think there is a short cut. Just keep reading datasheet of the chipsets and flash chips you are interested in or run into trouble with. Keep reading the list (as you are already doing). You can often learn something at the IRC channel.
Maybe you will be familier with SPI programming some day then you can write something for the followers :-)
