* Various bugfixes and workarounds for broken third-party software.
* Better error messages.
* Reliability fixes.
* Adjustable severity level for messages.
* Programmer-specific chip size limitation warnings.
* Multiple builtin frontends for flashrom are now possible.
* Increased strictness in board matching.
* Extensive selfchecks on startup to protect against miscompilation.
* Better timing precision for touchy flash chips.
* Do not rely on Linux kernel bugs for mapping memory.
* Improved documentation.
* Split frontend and backend functionality.
* Print runtime and build environment information.
The list of supported OSes and architectures is slowly getting longer, e.g. these have been tested: Linux, FreeBSD, NetBSD, DragonFly BSD, Nexenta, Solaris and Mac OS X. There's partial support for DOS (no USB/serial flashers) and Windows (no PCI flashers). Initial (partial) PowerPC and MIPS support has been merged, ARM support and other upcoming.
Also, the list of external (non-mainboard) programmers increases, e.g. there is support for NICs (3COM, Realtek, SMC, others upcoming), SATA/IDE cards from Silicon Image and Highpoint, some NVIDIA cards, and various USB- or parallelport- or serialport- programmers such as the Busirate, Dediprog SF100, FT2232-based SPI programmers and more.
More details at flashrom.org and in the list of supported chips, chipsets, baords, and programmers.
I uploaded an svn version slightly more recent than 0.9.2 to Debian unstable, which should reach Debian testing (and Ubuntu I guess) soonish.
Here's a quick introduction to using a cheap FTDI FT2232H based module (left-hand side on the photo) as a JTAG programmer together with the OpenOCD JTAG software for ARM and MIPS devices. The module I am using for thіs purpose is a DLP Design DLP-USB1232H, which is available from various sources (Digikey, Mouser, Saelig, and probably others) for 20-30 bucks plus shipping, depending on where you live.
By properly connecting the correct pins of the DLP-USB1232H to the target JTAG
device (I used an Olimex STM32-H103 eval board for testing) you can easily abuse the DLP-USB1232H as JTAG programmer. As I chose the proper DLP-USB1232H GPIOs for the TRST and (S)RST pins, OpenOCD even worked out of the box, without having to change a single line of code.
The only thing that's required is to provide OpenOCD with an interface config file that uses the usbjtag "layout". I have already submitted that config file upstream, I guess it should be merged soonish.
The usage is then pretty simple:
$ openocd -f interface/dlp-usb1232h.cfg -f board/olimex_stm32_h103.cfg
And in another xterm:
$ telnet localhost 4444 > init > reset halt > flash write_image erase fancyblink.bin 0x08000000 > reset
This flashes the given fancyblink.bin image onto the STM32-H103 eval board via the DLP-USB1232H JTAG programmer, where fancyblink.bin is an example program from my libopenstm32 project (that aims to create a full-blown firmware library for ST STM32 microcontrollers, similar to what avr-libc does for AVRs). Contributions for libopenstm32 (license is GPLv3 or later) are highly welcome btw., hint hint...
$ git clone git://libopenstm32.git.sourceforge.net/gitroot/libopenstm32/libopenstm32
Full schematics, datasheets, and detailed instructions for the JTAG programmer are available from a small page I created in my Random Projects wiki, which is intended for the various smaller projects I'm working on that don't warrant getting their own domain, wiki, etc:
The Random Projects wiki is open-for-all btw, feel free to use it for any freeish, software or hardware projects of your own if you want.
Anyway, the DLP-USB1232H is a really nice device as it can also be used for many other purposes, such as USB-to-Serial or SPI BIOS chip programming, but more on that in another blog post...
