80/100/132 column line width policy
by Carl-Daniel Hailfinger 14 Dec '18

14 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/

External programmers
by Carl-Daniel Hailfinger 25 Dec '15

25 Dec '15

Hi, I'm trying to find out which external programmers should be supported next. 1. There was talk of an AVR-based new programmer using the serprog protocol on IRC by someone with the nick "coldelectrons", but I have no idea if he/she is reading this mail. IMHO more hardware using the serprog protocol is always a good idea. 2. All those Willem/Sivava variants. People regularly request those, but I don't think anyone in here owns the hardware. 3. RayeR's SPIPGM. I have a preliminary patch which could work, but I don't have the hardware. Will send the patch to the list soon. 4. LPC^2, Milksop, CheapLPC and other programmers from the Xbox modding community. 5. Dozens of SPI programmer hardware projects scattered over the net. Too many to count, and I'm not sure which of them has more than one user. In general, it seems creating a new programmer hardware design is like writing IRC clients: A nice way to get started in the field. I have no problems merging flashrom support for all of them, but I won't implement support for all of them myself. Regards, Carl-Daniel -- http://www.hailfinger.org/

[PATCH] Add en29lv640b
by Rudolf Marek 10 Aug '14

10 Aug '14

Hi Following patch adds the en29lv640b which needs special command sequences in 8 bit mode. Also, 8 bit programming needs actually 16bit double byte program. The chip is found on bifferboard. Please check the patch and let me know. Signed-off-by: Rudolf Marek <r.marek(a)assembler.cz> Thanks Rudolf

[PATCH] Rename programmer registration functions
by Carl-Daniel Hailfinger 19 Jul '14

19 Jul '14

register_programmer suggests that we register a programmer. However, that function registers a master for a given bus type, and a programmer may support multiple masters (e.g. SPI, FWH). Rename a few other functions to be more consistent.

[PATCH] Add IT8212F as programmer
by Kyösti Mälkki 01 Jun '14

01 Jun '14

This PCI PATA controller can use 3V parallel flash upto 128kB. My card was identified as: PCI 1283:8212, subsystem 1283:0001. and labelled as: Innovision Multimedia LTD. EIO ATA133 RAID (DM-8401 Ver A) This particular card did not require setting of any GPIO signals to enable flash writing. My card has Pm39LV512 in PLCC32 package without socket.

Add timeout check to SPI bitbang bus request
by Carl-Daniel Hailfinger 29 Apr '14

29 Apr '14

Hi Iain, your Intel 82540EM which hangs on a flashrom run should spew "Timeout!" messages with this patch. It would be nice if you could tell us how long it waits for each chip probe so I can adjust the timeout value. Please note that this patch will _not_ fix the underlying issue, but I believe that an endless loop on possibly broken hardware is worse than aborting.

Flashrom stuck using 100% cpu while probing for a chip
by GatoLoko 28 Apr '14

28 Apr '14

I've tried to run flashrom -V to see if it could identify the chip on my new board (AsRock M3A-GLAN), and it got stuck while probing for the first chip. I've tried commenting out that specific chip (AMIC A25L05PT) and then it gets stuck on the next one. Then commented out all AMIC chips, and it got stuck on the next one (the first ATMEL on the list) I've tried with an older flashrom (0.9.2-r1141). It skipped some AMD chips, then got stuck on AMIC again. Talked with "tlt" and "stefanct" on irc and they asked for a strace and a gdb backtrace. Strace produced no results. Gdb log is attached. "stefanct" tried and reproduced it on a machine with nicintel_spi, but warned it was with an unsupported nic: http://paste.flashrom.org/view.php?id=738 -- GatoLoko
