VERIFIED. Hi and thanks for your report! The ":S" after the address range means that flashrom has detected that the data on the chip was already equal to the image you provided. I presume that you actually did write exactly that image to the chip already previously. Can you confirm that the contents of the chip really have changed? -- Kind regards/Mit freundlichen Grüßen, Stefan Tauner

flashrom ignores layout file?
by Ross Amans March 5, 2013

March 5, 2013

I can run flashrom under linux for read, but not yet write. Sandy Bridge / Patsburg C602 When I attempt to use a layout file, it likes it, but ignores it. No complaints, but instead of doing the 4 MB bios, it does the whole flash (8MB). command line: ./flashrom -r fll-19-w-bios.bin -c W25Q64 -p internal:laptop=this_is_not_a_laptop -i bios -l layout.flash -o fl-bios.log layout.flash: 00000000:0000ffff desc 00010000:003fffff me 00400000:007fffff bios fl-bios.log: flashrom v0.9.6.1-r1653 on Linux 3.7.5-201.fc18.x86_64 (x86_64) flashrom was built with libpci 3.1.10, GCC 4.7.2 20121109 (Red Hat 4.7.2-8), little endian Command line (12 args): ./flashroml -r fll-19-w-bios.bin -c W25Q64 -p internal:laptop=this_is_not_a_laptop -i bios -l layout.flash -o fl-bios.log romlayout 00000000 - 0000ffff named desc romlayout 00010000 - 003fffff named me romlayout 00400000 - 007fffff named bios Using region: "bios".

Assist in the development of SPI protocol.
by Сергей Бараненков March 4, 2013

March 4, 2013

Hello, please help in the development of the protocol SPI, I would like to implement a simple program to program MX25L3205. In this case, it is possible to program it with the Raspberry Pi, but you just want to understand. If you are not hard to help in your endeavors, if not difficult to specify where you can read and see the source code. I work in the Borland C + + 6.0. Thanks again -- Sincerely Sergey Baranenkov Engineer Grade 1 Interregional Center of ICT in the Bank of Russia (Central Bank)

Hello Wolfgang, I cannot do the commit to flashrom.org; I'm not a contributor, just a user. However, if you have a patch file I could apply it to the code on my system, and rebuild flashrom. That would get me out of the problem I have, and be able to reboot.

Hi, I took a closer look at your patch. It contains a lot of white space errors. Please make sure that this won't happen again. Checking data sheets to review such patches is no fun, dealing with other's white space errors is even worse ;) Some additions of chips are non-functional yet... e.g. there is no support for more than 24 bits in addresses, but some chips require that. Also, please do not send patches as base64 encoded attachments. -- Kind regards/Mit freundlichen Grüßen, Stefan Tauner
