80/100/132 column line width policy
by Carl-Daniel Hailfinger Dec. 15, 2018

Dec. 15, 2018

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 April 24, 2017

April 24, 2017

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. Found Spansion flash chip "S25FL128P......1" (16384 kB, SPI) on serprog. Found Spansion flash chip "S25FL128S......0" (16384 kB, SPI) on serprog. Found Spansion flash chip "S25FL128S......1" (16384 kB, SPI) on serprog. Found Spansion flash chip "S25FL129P......0" (16384 kB, SPI) on serprog. Found Spansion flash chip "S25FL129P......1" (16384 kB, SPI) on serprog. Multiple flash chip definitions match the detected chip(s): "S25FL128P......0", "S25FL128P......1", "S25FL128S......0", "S25FL128S......1", "S25FL129P......0", "S25FL129P......1" Please specify which chip definition to use with the -c <chipname> option. BTW: Chip was fund on a Dell-Systemboard.

[PATCH] Support device lists for programmers without PCI/USB IDs
by Carl-Daniel Hailfinger Feb. 29, 2016

Feb. 29, 2016

Based on an idea by Kyösti Mälkki. Issues: print_wiki is broken right now. Don't compile it in. The internal programmer is listed twice in -L output. Some programmers have stupid indentation in -L output.

[PATCH] fix chip size limiting in atapromise
by Carl-Daniel Hailfinger Feb. 18, 2016

Feb. 18, 2016

Atapromise chip size limiting has two bugs I didn't catch during review, but only in the moment of commit. The current code is checking model_id to remember if a chip has already been limited, but if flashchips.c contains two subsequent chips with different vendor_id but identical model_id the adjustment will not be done. Switch to checking the chip size instead. If a chip has multiple whole-chip erase functions, only one will be modified. Fix that.

That would mean that you try to write a 4 kB file to an 8 MB flash chip. flashrom won't allow that for good reasons. It seems like you are confusing two files IMHO. The 4 kB file is probably just the flash descriptor but that alone is probably not what you want to write. > and when i go to the properties of the image it is similar to > the chip's size. I certainly doubt that. It is more likely that you are comparing something else than flashrom does (i.e. you are looking at the wrong file). > Have tried using hex editor on windows and flashing that > format but keep getting same error message, hope you can help me with > regard to this, thankyou. You probably want to use a pre-built image by John Lewis. They should have the correct size... -- Kind regards/Mit freundlichen Grüßen, Stefan Tauner
