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

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.

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.

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

Good morning,
I am trying to revive a computer which had a failed BIOS update.
I bought a BUS Pirate and started using Flashrom to take a copy of an identical fully working model. Strangely this machine has two chips:
MX25L6405D
MX25L3205D
>From the dump's I have made, I believe the MX25L6405D holds the BIOS and the MX25L3205D possibly holds the ME Firmware.
Don't know if this is any use but an output from fptw64 on the working machine shows me the following:

This is a link to the datasheet for both chips : http://www.macronix.com/Lists/DataSheet/Attachments/2453/MX25L6405D,%203V...
It mentions something about having to give 9.5v-10.5v to the WP pin so maybe that is the problem? does this mean i would have to externally source this voltage outside of bus pirate to enable write enable properly?
Many Thanks

Hi,
I have a Dell OptiPlex 755 USFF which has an Atmel AT26DF321 SPI flash
chip (which is like an AT25DF321 and has the same device ID except it
doesn't have a HOLD# pin). I've used flashrom to read and write the
same chip on another board by ISP using a BeagleBone Black, 10-cm jumper
cables, a SOIC clip, and an ATX PSU.
However, flashrom with the same ISP setup fails to probe the chip on the
OptiPlex. I've tried two different known-working BBBs, different
cables, two different Pomona SOIC clips, connecting WP# to 3.3 V,
connecting what would be HOLD# on the AT25 to 3.3 V, and different
spispeed clock frequencies from 1 kHz to 10 MHz.
I've tried powering the chip (and the rest of the board's 3.3-V rail)
with a 3.3-V line of the ATX PSU, and I've tried instead powering the
whole board with the computer's 12-V PSU. I've also tried running
flashrom while holding down the power button to keep the system in
reset. Following some advice on <http://flashrom.org/ISP > I even tried
removing the DIMMs and CPU.
Every time I get only bytes of 0xff from the chip, as in the attached
log. In my experience that usually means either the programmer isn't
properly connected to the chip or the programmer uses a different data
voltage than the chip does. But I've checked and rechecked all of the
connections, and I know both the BBB and the AT26DF321 use 3.3-V data
signals.
Unfortunately there don't seem to be any schematics available for this
board (Dell model number 0HX555, ODM model number HX533 A00, ODM might
be Asustek or MiTAC). This system does have an Intel Management Engine
in the northbridge, but even if that was running I should at least be
able to probe the chip and read its contents.
Does anyone have any ideas of anything else I could try (short of
desoldering the chip from the board) or about what the problem may be?
Thanks,

Apart from the JEDEC ID (621614) the difference from the SST25WF080 is that
it lacks op codes 0xAD (AAI Word program) and 0x52 (32K erase).
Tested under Linux with spidev.
