Codes for noobs
by Thomas Saunders 05 Mar '12

Hi there :) We are building a mushroom farm out here in Denmark and were just wondering whether it was possible to change a chips code? We need the minimum temperature raised in the code. The chip itself is a G80F910C. Any help, however brief, is very much appreciated! Best wishes Thomas Saunders Danske Shiitake Hjelmagervej 7 8541 Skødstrup Danmark Tel: +4553144423 CVR: 33278721

Hello, and thanks for your mail. read tests are only useful in some cases (e.g. untested chips), for testing full board support we need a erase/write cycle. that does not mean that you should now erase your chip immediately, but the log as such does not help. if you ever try to update the firmware on that board on the other hand please send us a note. > I have question.

Is this correct? we can neither confirm nor deny this presumption. seriously... no that has nothing to do with secure boot afaik. these chips are used in many other devices not just PCs. the OTP area is usually just a few dozen bytes large, which might be enough for a few key hashes or so, but i doubt anyone would use them for this. it is just a feature to store a few bytes forever* and is probably only used in a few embedded devices. -- Kind regards/Mit freundlichen Grüßen, Stefan Tauner

Ubuntu daily builds PPA
by Stefan Tauner 04 Mar '12

04 Mar '12

Hi, i have setup a flashrom poject at http://launchpad.net/flashrom which auto-imports the svn every 6 hours and a package archive at http://launchpad.net/~flashrom-developers/+archive/flashrom-daily where new binaries are generated once a day whenever the svn has changed. currently there is a bug in launchpad itself that makes it impossible to use version 0.4 recipes (recipes are used to configure the autobuilders). this is the reason the package names are a bit awkward (e.g. 0.9.5.1+r1508-1-20120303 for svn r1512). it is basically named by {debversion}-{date}. it is the best i could come up with, that indicates the included source in at least some way (date), will upgrade to newer ubuntu versions when they become available and actually build in current launchpad. another problem is that the autobuilt binaries will output this: flashrom v0.9.5.1-runknown on Linux 2.6.35-32-generic (x86_64), built with libpci 3.1.7, GCC 4.4.5, little endian i.e. no svn revision. the only way to work around this would be a second svn tree with an already (auto-)exported version of flashrom... if we could manage to set that up, we could probably build our own package too without launchpad :) maybe it is useful anyway for someone... -- Kind regards/Mit freundlichen Grüßen, Stefan Tauner

I hope the Gertboard will accomplish some of that functionality. Designing our own PCB would be possible, sure, but my first focus is on getting the driver tested.

Raspberry Pi support as a programmer
by cmd_ 04 Mar '12

04 Mar '12

Hi guys, has past a lot of time since my last inquiry! Recently has appeared a ultra-cheap board named Raspberry Pi (perhaps you know http://www.raspberrypi.org/ ). This board has a powerful broadcom SoC that comes with USB, UART, I2C, SPI, GPIO ports... all for 25/35$, awsome. It could be a really versatile and powerful external/independent programmer for flashrom! Just take a look here: http://elinux.org/RPi_Low-level_peripherals The SPI bus could be used to program SPI flash chips (obviously) and GPIO for the other types. I propose two ideas, first one, support the board by flashrom software, second one, develop a daughter-board for the Raspberry-Pi to make a easy use of all (with sockets to program IC's or some buffers if necessary for other ones). That's all, greetings!

Zotac ZBOX-AD02-PLUS-U: System Testing
by Svetoslav Trochev 03 Mar '12

03 Mar '12

Hi Everyone, I just tested (read-only) one more system: Zotac ZBOX-AD02-PLUS-U. I am attaching the output files. I have question. Should I be concern very much about "This chip may contain one-time programmable memory. flashrom cannot read and may never be able to write it, hence it may not be able to completely clone the contents of this chip (see man page for details)."? I suspect this is about the UEFI secure boot option where the keys are( or would) be stored. Is this correct? Thank you, Svetoslav Trochev

ASRock H67M: Board Testing
by Svetoslav Trochev 03 Mar '12

03 Mar '12

Hi Everyone, I just run test on ASRock H67M mainboard. I am attaching the output files from "flashrom -V" and "lspci -nnvvxxx". After a quick search I could not find how to run "superiotool -deV" on Ubuntu, but once I figure it out I will attach the output as well. I hope the current info is useful for now. Thanks, Svetoslav Trochev
