Yes (well, I'd have to write up something), but the solution mentioned by Michael is way easier, so I'll wait until Michael has diagnosed the GPIO settings from the flashrom run on factory BIOS.

[PATCH] dummy programmer: blacklist SPI commands
by Carl-Daniel Hailfinger 08 Feb '12

08 Feb '12

Add optional SPI command blacklisting to the flash chip emulator in the dummy programmer. Usage: flashrom -p dummy:spi_blacklist=hexstring If hexstring is 0302, flashrom will blacklist command 0x03 (READ) and command 0x02 (WRITE). The hexstring can have up to 521 bytes (256 commands) length, and must not start with 0x. TODO: Should 0x at the beginning of hexstring be tolerated? Very useful for testing corner cases if you don't own a locked down Intel chipset and want to simulate such a thing.

AMD SB7xx/SB8xx w/IMC: enable specs
by Joshua Roys 03 Jan '12

03 Jan '12

Hello all, The specific board this is for is the Supermicro H8DGT. Attached is only the specification, which is not guaranteed to be correct. Use with care. Also, after using this, you may want to turn off and unplug the computer for a few minutes to restore the correct operational state. The AMD SB700/710/750 Register Reference Guide (#43009) was used as a reference. Thanks, Josh

[PATCH] Implement unknown Dediprog commands
by Carl-Daniel Hailfinger 20 Dec '11

20 Dec '11

Secret knowledge is cool, but public knowledge is better. Implement all Dediprog commands found in USB traces, even if their purpose is not yet known. Annotate unknown commands with info about the call sequence they are embedded in and the firmware version of the log. Add a new shutdown command for firmware 5.x.

patch to add support for Xilinx parallel III/DLC5 programmer cable
by Jakab Peter 12 Sep '11

12 Sep '11

Hi list, I modified the rayer spi programmer source to be used with a Xilinx parallel III (also called DLC5) programmer cable. It's a trivial change of parallel port pins, but I did not know how the support for this cable should be included into the source code. Copying the same code to a separate file may not be a good idea. --- flashrom/rayer_spi.c 2010-09-18 19:48:27.000000000 +0200 +++ ../flashrom/rayer_spi.c 2010-09-18 02:12:59.000000000 +0200 @@ -37,11 +37,11 @@ * independent and are bitshift values, not real pin numbers. */ /* Pins for master->slave direction */ -#define SPI_CS_PIN 5 -#define SPI_SCK_PIN 6 -#define SPI_MOSI_PIN 7 +#define SPI_CS_PIN 2 +#define SPI_SCK_PIN 1 +#define SPI_MOSI_PIN 0 /* Pins for slave->master direction */ -#define SPI_MISO_PIN 6 +#define SPI_MISO_PIN 4 static int lpt_iobase; Thank you for working on this software, with access to the source code I was able to program my w25q64 flash chip. -- Peter JAKAB http://jap.hu/

[PATCH] Add Linux SPI support
by Sven Schnelle 07 Sep '11

07 Sep '11

Hi List, this patch adds support for the Linux SPI subsystem. See http://www.kernel.org/doc/Documentation/spi/spidev for a short introduction. Usage is as follows: flashrom -p linux_spi:dev=/dev/spidevX.Y where X is the bus number, and Y device. It accepts an optional parameter 'speed' which allows to set the SPI CLK speed in KHz. I'm using a AVR32 Board (http://www.atmel.com/dyn/products/tools_card.asp?tool_id=4102) to program my ThinkPad X60, but it should work on every Linux system.

Re: [flashrom] [PATCH] Board enable for ASUS P5LP-LE

HP calls it "Leonite" or "Leonite-GL8E". http://h10025.www1.hp.com/ewfrf/wc/document?lc=en&dlc=en&cc=us&docname=c008… But that would have been too easy. There are a bunch of other boards on the HP site which are also called P5LP-LE, but have different HP code names. From a quick glance I see at least: P5LP-LE (Leonite) P5LP-LE (Leonite2) P5LP-LE (Lithium) P5LP-LE (Limestone) P5LP-LE (Emery) Fun! I don't know how to differ between them, the dmidecode from Leon Zhang <leoncamel(a)gmail.com> said: DMI string system-manufacturer: "EPSON DIRECT CORP." DMI string system-product-name: "Endeavor MT7700" DMI string system-version: "" DMI string baseboard-manufacturer: "ASUSTek Computer INC." DMI string baseboard-product-name: "P5LP-LE" We don't know if other "P5LP-LE" might have the "Leonite" (or other) HP code name in there or not. Maybe something is printed as silkscreen on the board? An then one of these HP OEM boards is built into the Epson "Endeavor MT7700" system/PC. So it's a bit unclear which vendor/board name we should use in this case. It's probably best to mention all of them for better googling results. Attached is a slightly updated patch for review, let me know what you think.
