{{DISPLAYTITLE:flashprog/v1.2}}

Our third feature release brings some exciting ground work to boost external
programming: ''Flashprog'' now supports multi-i/o reads ''and'' QPI, finally!
So far, this works with Dediprog SF600 and its successors, FT4222H-based
programmers and bit banging.

= What's new? =

== Multi I/O ==

Our generic SPI25 flash driver was reworked to support different read
commands, primarily to support dual and quad-i/o reads. To actually make
use of it, a huge revamp of our flash-chip database was necessary. So far
we only kept track of QPI support (vaguely), but didn't note what multi-i/o
commands are available in SPI mode.

Dual and quad-i/o reads are usable with Dediprog SF600 and its successors,
providing a nice speed-up for those. They can also be used with the new
''ft4222_spi'' driver and bitbanging via ''linux_gpio_spi''. For those,
however, full QPI takes precedence (see below).

As dual i/o only requires the traditional four SPI signal lines, it's
enabled by default for compatible programmer / chip combinations. To
enable quad i/o, a '''iomode=quad''' programmer argument is required
(plus the necessary physical setup, of course). Many chips also have a
quad-enable (QE) configuration bit that has to be set. Flashprog will
automatically try to set a volatile QE bit, if present. However setting
non-volatile bits currently requires some work-in-progress patches.

SF600 programmers with older (protocol v2) firmware are untested and
still default to single i/o.

== QPI ==

Flash chips with QPI support allow to send and receive ''all'' data via
four signal lines at once. This, however requires a compatible programmer.
QPI is currently only useful with the new ''ft4222_spi'' driver and can
additionally be tested with the ''linux_gpio_spi'' bitbanging driver.
If the prerequisites for quad i/o are given and programmer and flash
support QPI, it will be used by default.

== FTDI FT4222H ==

''Flashprog'' has a new driver ''ft4222_spi'' to use FT4222H based USB-SPI
bridges. The chip supports QPI, which was the original incentive to look
into this topic. The FT4222H i/o buffers take an external Vref, which
also makes it useable for 1.8V applications without additional translation.
With QPI at 40MHz, it can read about 6.5 MiB/s.

== Meson ==

Some smaller Meson fixes were applied that we discovered during testing
of the last release. The test script was updated to test and compare (a
little) builds with Make and Meson. This should further help to transition
with reduced risk of regressions.

= Other Changes =

* README was update a little and converted to markdown.
* ''Flashprog'' has new ''udev'' rules for a bunch of USB programmers.
* Some patches originally for ''flashrom'' were applied to support multi-i/o related configuration registers.
* Some smaller fixups around the currently erase-block selection (minor speed-up, and fixed SFDP with ''ichspi'' in corner cases).
* Support for the CH347F variant was added.
* While ''flashprog'' should fully support AMD systems up to Zen 4 (if not locked down too much), we bail out now when PCI config space reads all 'ff' (discovered on a Rembrandt ThinkPad, reasons are currently unknown).
