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

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/

Spansion S25FL128P......X

by The Raven

I have a spansion S25FL128P......X chip and can do some tests. The "problem" is that i don't know if its an 0 or an 1. On the chip i see only "FL128PIF" and one line lower i see "00299012 C". Probing works (id1 0x01, id2 0x2018): Calibrating delay loop... OK. serprog: Programmer name is "serprog-duino" Found Spansion flash chip "S25FL128P......0" (16384 kB, SPI) on serprog.

Hello flashrom team, Please find appended a problem report of a failed attempt at probing the flash on T530.

Re: [flashrom] Query Reg excluding the dependency with the libusb and libftdi

There are several CONFIG_* variables that can be (un)set when you build flashrom. They are listed under "Default settings of CONFIG_* variables" in the Makefile, and you can change the defaults however you like. You probably only need CONFIG_INTERNAL enabled for your desired use case. Alternatively, you can look at the output of the make command to see what's being included by default and override the default. For example, to explicitly disable USB Blaster you can use run "CONFIG_USBBLASTER_SPI=no make". -- David Hendricks (dhendrix) Systems Software Engineer, Google Inc.

Query Reg excluding the dependency with the libusb and libftdi

by RAJESH DASARI

Hi , Could some one please tell me is there any way to remove the dependency with the libusb and libftdi while building the flashrom binary . I use flashrom tool only to the flash the BIOS not for any USB device. I don't need support for FT2232, Dediprog or USB-Blaster. Thanks, Rajesh Dasari.

FreeBsd killed my BIOS

by Christopher Robinson

After a clean install of FreeBsd, my Sun Ultra 20 x86 AMD64 desktop would not reboot.I only got the Sun Microsytems logo on my monitor, nothing else happened. I think I needto reflash the BIOS and would like to do this with flashrom. However, I see that no live cdsare available. I plan to try Hiren's (earlier on I tried out systemrescue for another issue,with no success). However, I don't see how this will boot the system without first flashing theBIOS, if that is the problem. Sort of a Catch-22. The same seems to apply to Parted Magic.
