Path syntax for Linux Flashrom?
by a webuser July 22, 2015

July 22, 2015

I've found lots of helpful info on using Flashrom for updating an HP xw9400 BIOS using an Ubuntu Live DVD, but the commands never seem to include any path information! For example: flashrom -r biosbackup.rom flashrom -E flashrom -w 7D6_0403.bin In the first and third lines, where does Flashrom assume the files are located if no path is supplied? If I install a floppy to read/write to, what is the path syntax? About the Ubuntu Live DVD, could someone add a little more info to these cryptic instructions to install Flashrom (is this multiple steps)? install flashrom (open a terminal from the start menu, do sudo su) using apt-get install flashrom Thanks!

Flashrom is just one of many programs which run on many distributions and variety of operating systems, therefore it is not practical to go that deep into details about the OS's package management. That is something you'll need to learn on your own. There's a non-zero chance that something will go horribly wrong when you run flashrom and you'll need to do something to recover. I suggest that you get comfortable with your tools and environment before doing something that is potentially destructive. -- David Hendricks (dhendrix) Systems Software Engineer, Google Inc.

Hi, Someone had already reverse engineered the protocol and created an SPI flasher tool for that: https://github.com/setarcos/ch341prog Using this code it won't be a big issue to add flashrom support.

user question about the ITE IT8518E SuperIO / EC
by hzh July 13, 2015

July 13, 2015

Hello flashrom / coreboot / lm_sensors team I'm not even completely sure if I am on the correct mailinglist for my question so please excuse if I asked in the wrong category. Well, my question is quite generic. I have a laptop here which would in theory be very fine for Coreboot with a freedom OS. It's a HP 635. It's based mainly on AMD tech (E-350, A50M chipset or something close to that), Realtek (NIC, card reader) and Atheros (wireless) components. So kind of everything works. Well. Nearly. You know, there was some sort of chips, that never really cause me trouble in the past. They were there and would just always work: The Super IO chips. ITE, Fintek, Winbond, whatever. But now there is this ITE IT8518E Super IO (correctly it's an EC) which just won't seem to have a driver or documentation. HP wasn't really of help here as far as I reached anyone there. ITE was slow to respond and I don't how if I can just ask them "hey, it would be nice to have specs for writing a freedom driver for the Linux (BSD/whatever) kernel / lm_sensors and have it supported for flashrom / coreboot". Especially since I am no code hacker, I'm one of those strange users. ;) Without support for that chip there likely won't be any flashrom and thus no coreboot, right? That would be sad since otherwise the box is very suitable and fairly well equipped for the price (also has a non glare screen). I can provide you with a bunch of outputs from flashrom, superiotool, lm_sensors, lspci, lshw, dmidecode, acpidump and whatsnot if that is of help. Greetings and have nice week Haldor

Fwd: PM25LD512-SCE

Hi Stefan, thanks for your help! I have updated with those packages and now I can recognize the chip. However, I have an issue while trying to write the flash, here is the basic output: Calibrating delay loop... OK. Found PMC flash chip "Pm25LD512(C)" (64 kB, SPI) on ft2232_spi. Block protection could not be disabled! Reading old flash chip contents... done. Erasing and writing flash chip... and never progress. Moreover, no signals are present on the PINs and this is a part of the verbose output: Found PMC flash chip "Pm25LD512(C)" (64 kB, SPI). Some block protection in effect, disabling... Block protection could not be disabled! Chip status register is 0x20. Chip status register: Status Register Write Disable (SRWD, SRP, ...) is not set Chip status register: Bit 6 is not set Chip status register: Bit 5 is set Chip status register: Block Protect 2 (BP2) is not set Chip status register: Block Protect 1 (BP1) is not set Chip status register: Block Protect 0 (BP0) is not set Chip status register: Write Enable Latch (WEL) is not set Chip status register: Write In Progress (WIP/BUSY) is not set Reading old flash chip contents... done.

Support for ENE KB9012QF A3
by LIY 2012 July 12, 2015

July 12, 2015

Hello, I would like to request flashrom support for the ENE KB9012QF A3 chip. This chip has 128KB of internal flash memory that can be accessed through the SPI interface. The data sheet for this chip can be found at the following URL http://www.s-manuals.com/pdf/datasheet/k/b/kb9012_r0.9_ene.pdf The relevant section starts on page 218. I was able to read the contents of the chip using the SPI bus on my Raspberry pi, but unfortunately, I lack the skills to write to the chip. There is very little documentation on the write command, and I was unable to get it working in my tests. Thank you for your consideration.

Re: [flashrom] 3Com 3C905-TX Support
by Bruno Rocca July 9, 2015

Hi Stefan, Thanks for your help and your time, I have tested the new .exe but flashrom can't detect any flash/eeprom chip on the NIC. I tested AMD and SST chips (DIP32 and PLCC32 with an adapter). I have the same card as Idwer, same model, same revision. Maybe this card was not meant for updating the chip, after all, or maybe the card is blocking write access to the flash chip. Thank you again, if you need help testing another NIC and Flash chips, just let me know.

I also have a 3Com 3C905-TX, but flashrom does not support it. The vendor ID is 10B7 and the device ID is 9050. Is there any way to force flashrom to flash with this NIC? I hope this can be done. Thank you very much for your help, flashrom is an excelent tool. Hi, there is a pci programmer parameter to select one of multiple PCI devices but I don't think there is a way to force the driver to use it, if it does not in its list of supported devices. I am not exactly sure why we have never added the ID. I think Idwer had problem with his model, but apparently someone has used the following patch successfully but it was not merged. http://patchwork.coreboot.org/patch/4086/raw/ I have applied a similar patch (attached) and built a DOS executable for you: http://buildbot.flashrom.org/buildresults/flashrom-000180-Hie/dos/flashrom.… -- Kind regards/Mit freundlichen Grüßen, Stefan Tauner
