There is a focus on x86, but MIPS, PowerPC and other architectures are supported as well. flashrom is independent of the MTD framework, so you don't need to boot a special kernel for a firmware upgrade. That said, writing a flashrom driver for your hardware is pretty easy. You could even use existing kernel code for your device as a template for the flashrom driver since the license is compatible. If you have any questions, please ask. Regards, Carl-Daniel

Firmware flashing/dumping for DVD-burners
by Mattias Mattsson 29 Sep '10

29 Sep '10

Hi, I did some googling and found some tools with functionality that maybe could be integrated into flashrom. flasher is a tool to dump/flash LG drives with Renesas chipsets. (GPLv3) git://flasher.git.sourceforge.net/gitroot/flasher/flasher http://sourceforge.net/projects/flasher/ There is source code (for OS X) to flash firmware on Matshita drives: http://forum.rpc1.org/viewtopic.php?t=42953#p207704 At one point there was source available tool to also dump firmware from Matshita drives. (Unfortunately the link referenced in this forum post has expired.) http://forum.rpc1.org/viewtopic.php?t=43046 Some other tools for dumping/flashing are listed here, most of them without source code: http://forum.rpc1.org/viewtopic.php?t=44362 -mattias

Fwd: [RFC] Online firmware upgrade in non-embedded systems
by Mattias Mattsson 28 Sep '10

28 Sep '10

Maybe this is interesting for us as well? ---------- Forwarded message ---------- From: Ben Hutchings <bhutchings(a)solarflare.com> Date: Tuesday, September 28, 2010 Subject: [RFC] Online firmware upgrade in non-embedded systems To: netdev <netdev(a)vger.kernel.org>, linux-kernel <linux-kernel(a)vger.kernel.org>, linux-mtd <linux-mtd(a)lists.infradead.org> Cc: sf-linux-drivers <linux-net-drivers(a)solarflare.com> Network and disk controllers normally have at least some firmware in flash to support their use as boot devices. Solarflare's current network adapters can have as many as 4 distinct firmware partitions: one for each PHY, one for the management CPU and one for net-boot. Any or all of these may need to be updated in the field, to fix bugs or to add features. (Furthermore, the net-boot firmware is based on gPXE and is therefore modifiable by any user.) Currently the sfc network driver is optionally combined with an MTD driver (CONFIG_SFC_MTD) which exposes all upgradable firmware and configuration partitions in flash. This works nicely in kernels with MTD enabled, but since MTD is mainly used in embedded systems with on-board flash it is often disabled in distribution kernels and custom kernels alike. This leaves users of sfc unable to upgrade firmware without rebuilding the kernel or booting some other distribution. The lack of widespread MTD support is a regular cause of support requests. There are two main alternatives I'm aware of: - Use the ethtool ETHTOOL_SEEPROM command with multiple magic numbers for different partitions. bnx2x does something a little like this for PHY firmware upgrades. The ethtool core passes in a page at a time so this won't work well with flash block sizes greater than PAGE_SIZE. - Use the ethtool ETHTOOL_FLASHDEV command. It's intended for precisely this purpose, but the driver is supposed to implement it using request_firmware(). That seems to require any firmware update program to integrate with udev or to copy firmware images under /lib/firmware even though they are one-time updates. That doesn't make a lot of sense to me. Am I missing something? Of course these are both specific to network devices; it seems deisrable to have a more general convention for online firmware upgrades. MTDs clearly are more generally applicable, and pretty much every computer does have flash storage for firmware and boot configuration, so perhaps it should be treated as more of a standard feature? Ben. -- Ben Hutchings, Senior Software Engineer, Solarflare Communications Not speaking for my employer; that's the marketing department's job. They asked us to note that Solarflare product names are trademarked. ______________________________________________________ Linux MTD discussion mailing list http://lists.infradead.org/mailman/listinfo/linux-mtd/ -- -mattias

Success report: MSI MS-7501 (K9A2VM-FD)
by Uwe Hermann 28 Sep '10

28 Sep '10

Here's a quick test report on an SB700 board I just tested, the MSI MS-7501 (K9A2VM-FD). The chip is a soldered SO8 unfortunately, but well... no risk, no fun, so I tried a write operation and it worked. Logs attached.

Flashrom and drive firmware update
by Cirdec AREVIR 28 Sep '10

28 Sep '10

Hello, Just a little question for the flashrom project : Could we expect to use Flashrom for drive firmware update ? Would that be a lot of work ? Do we need NDAs data ? The question come because I can not flash an OEM Sony-Optiarc Bluray drive with the official firmware release because OEM are encrypted : I understand better what OEM means now ... :-( . So, with the wonderful Flashrom project existing I have some hope. Thank you. Cirdec. ++
