However, we will add the new names to the in-program (and hence wiki) database so that this new information becomes public. Thanks for the heads up, Victor. -- Kind regards/Mit freundlichen Grüßen, Stefan Tauner

80/100/132 column line width policy
by Carl-Daniel Hailfinger 15 Dec '18

15 Dec '18

Hi, we're hitting the 80 column limit in our code in ways which actually reduce readability for the code. Examples are various multiline messages and complicated nested code where refactoring to a separate function doesn't make sense. Keeping the old 80 column limit is not really an option anymore. Standard terminal sizes have one of 80, 100 or 132 columns. Given the monitor resolutions many people have nowadays, I think it is safe to say that you can fit two xterms with 100 columns horizonally next to each other. 100 columns should also be sufficient for a msg_p* of roughly 80 columns of text. 132 columns provide more leeway, but IMHO that would be too wide for good readability (and my screen can't fit two xterms side-by-side anymore). Of course some files have sections where any column limit is not acceptable (board lists etc.), but the column limit violations should be limited to the affected file sections, not whole files. Comments? I'd like to get this decided today or tomorrow so we know where we need line breaks in Stefan Tauner's new struct flashchip patch. Regards, Carl-Daniel -- http://www.hailfinger.org/

FOSDEM Hardware Enablement Devroom
by Paul Kocialkowski 04 Dec '18

04 Dec '18

A Hardware Enablement devroom will be taking place at FOSDEM this year, on Sunday 10 December 2017. This newly-created devroom is the result of 3 proposals that were merged together. It is co-organized by several individuals. The devroom covers all aspects related to hardware enablement and support with free software, including aspects related to boot software, firmwares, drivers and userspace tools and adaptation. Proposals for talks related to these topics are welcome and can be submitted until Sunday 26 November 2017 via the pentabarf interface. Short talks are encouraged over longer ones in order to cover a wide range of topics. The announcement for the devroom, that contains all the useful information, was published at: https://lists.fosdem.org/pipermail/fosdem/2017-October/002649.html Cheers and see you at FOSDEM! -- Paul Kocialkowski, developer of free digital technology and hardware support Website: https://www.paulk.fr/ Coding blog: https://code.paulk.fr/ Git repositories: https://git.paulk.fr/ https://git.code.paulk.fr/

64Mbit IS25LP064A not recognized
by Buhrow, Simon 29 Aug '18

29 Aug '18

Hi, Having a 64Mbit IS25LP064A and using flashrom 1.0, when calling sudo flashrom -p ft2232_spi:type=2232H,port=A,divisor=100 I get: flashrom v1.0 on Linux 4.15.0-33-generic (x86_64) ... Using clock_gettime for delay loops (clk_id: 1, resolution: 1ns). Found Generic flash chip "unknown SPI chip (RDID)" (0 kB, SPI) on ft2232_spi. ... :( Writing and reading commands break with the same message. So I checked the table at https://www.flashrom.org/Supported_hardware The chip is not supported yet. But it says that chips supporting JESD216 should work. Measuring the signal I got that the command given above does first a RDJDID Operation and later the RDSFDP operation (which should be according to JESD216). I attach the signals. You can see the the operations and what is done. According to the datasheet is MF7-MF0: 9Dh and Memory Type + Capacity (ID15 - ID0): 6017h. Which you can see on the RDJDID signals image. I know the signal quality is not the best but doing real improves would cost a lot of time. As I already successfully programmed another supported chip and because the Flash chip response the right way I think that it´s not a signal integrity problem. So my questions are: 1) Does "unknown SPI chip (RDID)" mean "it´s not in the database" or does it mean "RDID could not be read successfully"? 2) If it means "RDID could not be read successfully": Is there any other possibility than signal integrity why flashrom does not show the right RDID? 3) If it means "it´s not in the database": Would adding it to the database solve the problem or is that not crucial? 4) Does flashrom supports flashs with memory of 64Mbit? As I can´t find any in the supported hardware list. The datasheet of the flash can be obtained from: https://www.mouser.de/datasheet/2/198/25LP032-64A-B-737452.pdf Btw: the JESD216 link at https://www.flashrom.org/Supported_hardware does not work. May be https://www.jedec.org/standards-documents/docs/jesd216b is what should be linked? Regards, Simon

Re: [flashrom] MX25L6473F Bios

Hello B., I guess you might have solved your problem by now, anyway: On 13.07.2018 15:56, B. Ford wrote: > I am trying to read a MX25L6473F bios chip, it is in your supported list > of chips.

MX25L6473F was added rather late indeed. Though, it's one of those chips that share their ID with many others. For flashrom-0.9.9 this should work: -c MX25L6436E/MX25L6445E/MX25L6465E/MX25L6473E They are all compatible to the 73F as far as flashrom is concerned. Nico

Would you like to get reports from all of them? it seems the issue is already mitigated by other changes in the core of flashrom (though, the actual bug is still there). For the moment, it would be nice if you could try flashrom-1.0 to see if the issue persists. Nico
