[PATCH] spi25: ignore 0x00 as a manufacturer id in the generic match

by Urja Rannikko

Saying that manufacturer id 0x00 is an "unknown SPI chip" just confuses people with external programmers without a proper connection to a chip and makes them think flashrom doesnt support the chip they're trying to use. Also causes unnecessary -c requirement with a multiple-slot (FWH/LPC and SPI) serprog device i was testing.

Write-Test for "M25P10-A"

by The Raven

Hello, this chip is marked as "untested" in write mode. So here are my test-results: Erase in d8-Mode is not working (see log). But i think it's the already known "serprog bug". Erase in c7-mode is ok. Write is working in both modes. But i don't know why in c7-mode the log shows: 0x000000-0x007fff:W, 0x008000-0x00ffff:S, 0x010000-0x017fff:S, 0x018000-0x01ffff:S I have created the test-file with dd and urandom. The file (131072 byte) is full with data. So it should write (W) not only to 0x007fff. Strange! If you need more logs or infos, let me know. BTW: The chip is labeled "25P10VP". I see nothing with "-A". And the chip was found on a "Maxtor" hard disk drive.

Gigabyte H55M-S2H with 2 Macronix MX25L6465EM2I flash chips

by Александр Трубицын

Hello! I have Gigabyte H55M-S2H motherboard with 2 MX25L6465EM2I SPI flash chips, but now flashrom asks me to choose from 3 different chips: Multiple flash chip definitions match the detected chip(s): "MX25L6405(D)", "MX25L6406E/MX25L6436E", "MX25L6445E/MX25L6473E" Please specify which chip definition to use with the -c <chipname> option. I find chip datasheet where: http://www.datasheetarchive.com/dl/Datasheets-IS78/DSAH00369299.pdf In the table 6 (ID Definitions) of this datasheet we can see RDID=0x2017 1. Is it possible to use one of supposed chip or a new one? 2. Can you add comment about MX25L6465 in the flashchips.h after MX25L6405 or new definition in flashchips.c ? 3. Is it possible to determine flash chip by RDID and RES (Read Electronic Signature)? -- Best regards Alexander.V Trubitsyn

Re: [flashrom] Compile under MinGW32, how? (Topolinux)

by Topolinux

Hi Stefan, thank you very much for the prompt reply! Honestly I don't understand all you wrote although I'll do my best in order to do it. In the meantime I'm digging the matter having find some answers to my questions, but seems to me too complicated for me, out of my capabilities. OK, I can turn off libusb, but then the program that I'll get will be working? I guess it will be. Now I understand why nobody provide Windows version of flashrom each time there is an upgrade. Only Linux version that it is more easily obtainable. You wrote about cross-compiling flashrom for Windows, maybe that is more easy than compiling on a Windows system, which could be one solution. By reading http://flashrom.org/Windows page seems to me cross-compiling on Linux for Windows is more complicated though. If it isn't too much trouble could you please describe how do the job? I mean a description of your MinGW installation and the exact commands issued. Instructions on the site say $ cd flashrom $ make are enough in order to compile under Windows. Instead on Linux for Windows you need $ make CC=i586-mingw32msvc-gcc CPPFLAGS="-I.../libusb-headers/ -I.../libftdi-headers/" LDFLAGS="-L.../libusb-static/ -L.../libftdi-static/" If it could be possible to see a real life example I think it would be of much help. Another thing. In your example you compile with "i686" option while in the instructions on the flashrom Windows site it's used the "i586". Compiling by $ cd flashrom $ make there isn't any of the two options, so which option will be used in order to compile? My purpose is to get a flahrom executable which will be able to run on any generic Windows machine. Snapshots on http://ra.openbios.org/~idwer/flashrom/mingw/ I guess have been compiled in that way, apart from the mingw32-w64-flashrom-r1781.exe of course.

The documentation is not up to date. flashrom requires libusb now at build time because of the inclusion of a libusb-based programmer. You can turn it off (and thus enable compilation without libusb) by adding CONFIG_PICKIT2_SPI=no to the command line (for now). I am only cross-compiling flashrom for windows so I am not sure if that helps you, but there I am using the newly introduced LIBS_BASE make parameter to indicate the path containing the include and lib directories with the respective header and library files like so: make LIBS_BASE=/home/flashrom/cross-libs/i686-w64-mingw32 The layout within that directory should look like the common unix layout, i.e. /lib containing *.a, /bin with *.dll and /include with *.h files. The PKG_CONFIG_PATH message can be ignored usually. The default will probably work anyway. -- Kind regards/Mit freundlichen Gr??en, Stefan Tauner ------------------------------ Subject: Digest Footer _______________________________________________ flashrom mailing list flashrom(a)flashrom.org http://www.flashrom.org/mailman/listinfo/flashrom ------------------------------ End of flashrom Digest, Vol 70, Issue 28 ****************************************

This is also an error in the existing definition of the GD25LQ32. Apart from these repeated copy & paste errors it looks good. Please fix them so that I can commit your first flashrom contribution, thanks!

W836xx: To be filled by O.E.M.: flashrom -V

by Florian Schroeter

Dear flashrom Developers, I am writing you because I want to set up a proper Linux on my Laptop, which I imported from china. It's clearly an imitation of some Acer Aspire One Model. When I got it, the packaging was labeled as "Spire One"... W-Lan and Bluetooth, sound, battery state and brightness controls as well as function keys seem to work under windows but not under Linux. I guess the ACPI tables provided by the hardware do poorly support any OS different from Microsoft Windows. I had hoped that a BIOS update could maybe fix the buggy ACPI tables but wasn't able to update the bios using flashrom. As suggested by your tool I'll put the verbose output of flashrom into the attachment. Kind regards Florian Schröter
