Re-building after failed flash
by Clay Daniels 07 Apr '21

07 Apr '21

I should have been more patient, but I used flashrom to attempt to install a bios update from MSI, and it kept looping through the attempt giving an error message about "unable to erase". I eventually got the pid # with top, and killed the job. Everything seemed OK, so it was late and I shut the computer down with the normal Ubuntu shutdown. The next day, it would not boot. By not boot, the fan & lights came on, I thought I heard hard drives, but absolutely no video. I messed with it for several days, then ordered a new motherboard. After installing the new mb, hopefully correctly, I have the same problem. I can't think of anything left undone. Is it possible a failed flash can fry the video card? I re-used memory, etc, but the monitor shows no activity. When I built this computer in September 2019, the motherboard worked out of the box, and already had a bios installed. I am assuming the new motherboard has a bios installed too. Any help appreciated, Clay Daniels

Re: (Re)Unsuccessful Read with FlashRom

If you suspect that your BIOS is infected (BadBIOS?), I could only suggest doing a hardware ISP flashing with one of the flashrom-supported programmers (i.e. green PCB ch341a) and a test clip like SOIC8 (to be able to attach to a chip without any soldering) while the board is turned off of course. This should be the most reliable. Before flashing a new known good BIOS image that you might obtain i.e. by extracting from a manufacturer's update utility, please dump the previous contents with a programmer: so that you'll be able to recover from it just in case, and maybe even look through it for any hard evidence of a BIOS virus to share it with the community (if that's really true, could be quite interesting for research purposes). Also I copy this message to a flashrom mailing list, in case someone else could also advise you. On Wed, Apr 7, 2021 at 2:05 PM Rahngue NGARIERA <youetonam(a)gmail.com> wrote: >> >> Hi Mike.

And checking on the main board I did see that chip. It's AT26DF081A. I did try to read on FlashRom 0.9.4 (on DOS) using the -c parameter with AT26DF081A first (as in -c AT26DF081A) but that failed. Then just to see, I tried to read with -c AT25DF081A ( since 0.9.4 was seeing two chips). But it also failed.

flashrom 1.2
by KP142EH12 06 Apr '21

06 Apr '21

Hello! I'm try to build flashrom 1.2 for windows with FTDI support, but i can't. I'm try on debian with i686-w64-mingw32-gcc, i'm put ftdi files in /usr/...mingw32/bin|include|lib, but 'make' tell me "Checking for FTDI support... not found." and many errors in the end (ich_descriptors.c). Maybe you can give me advice on how to build them or share a compiled binary with me. I'm sorry for disturbing, many thanks and sorry for stupid (maybe) questions)

[HowardHo2021 DOS Port] RE: Changes made for FlashRom DOS port
by howardho2021＠gmail.com 05 Apr '21

05 Apr '21

Hi, Thanks for your email. Unfortunately, I did not specifically write down the changes I made in a document. However, you may check the commit history at my “flashrom for DOS” port repository here <https://github.com/HowardHo2021/flashrom-DOS-port> . If you wish, you can clone that repository and follow the instructions I wrote in “README_DOS” to compile your own copy. For future correspondence, please use howardho2021(a)gmail.com <mailto:howardho2021@gmail.com> instead. Thanks. From: Rahngue NGARIERA <youetonam(a)gmail.com> Sent: Saturday, April 3, 2021 11:58 PM Subject: Changes made for FlashRom DOS port Hi HowardHo. I haven't seen your list of changes to the original FlashRom (to get a working DOS port) on your Git pages. Could you please post them there or email it to me? I'd very much like to know. 'Cause I wasn't able to get it done with the original FlashRom. Thanks for your help, Etonam. PS: As you advised me, I sent my Read/Probe failure email to FlashRom.org And I'm waiting for their answer.

Using JTAG-lock-pick Tiny 2 as flashrom programmer
by mailmuncher mailmuncher 05 Apr '21

05 Apr '21

Hello! Thanks for flashrom! Had a question about using "JTAG-lock-pick Tiny 2" (https://distortec.com/jtag-lock-pick-tiny-2/) as flashrom programmer. It is a FT232H based openocd jtag programmer so I figured I could use it like so: $ flashrom -p ft2232_spi:type=232H -r dump.rom$ flashrom -p ft2232_spi:type=232H -w bios.rom But the PID is not the standard FT232H of 0x6014 so I adjusted the 232H PID value in ft2232_spi.c to match: 0x6014 --> 0x8220. Then re-compiled and now flashrom seems to recognize the device. But still not able to read any spi eeproms. Would be great to get any input on how I could make this work or things I could try. ThanksVivek

Programmer initialization failed
by Dominik G 04 Apr '21

04 Apr '21

Hi, I am trying to run flashrom but I am not able to. For my program I use Arduino Nano on which I uploaded frser-duino. I repeated the steps in the instructions on your site on the other computer and virtual machine. I don't know why it doesn't work. I even tried to upload the old version of the serprog-duino from github. Every time I type the basic command *"flashrom -p serprog:dev=/dev/ ttyUSB0: 2000000" * I get the error *"Error: cannot synchronize protocol - check communications and reset device?* *"Error: Programmer initialization failed .. "* I tried to edit the makefile attached to frser-duino, but there's not much to change there. According to the creator, the file is preconfigured for atmega328p which is in my arduino so it should work right away. I also edited the command changing the last value from 2000000 to 9600, 56700, 115200 and 256000. I hope you have some idea. I suspect that the matter may be related to the software loaded on arduino, but looking at github from May 17, 2020, the author of frser-duino did not manage to correct the readme file at the request of one of the users in the "Issues" section.

Unsuccessful Read using FlashRom
by Rahngue NGARIERA 04 Apr '21

04 Apr '21

Hi there. I tried to probe for/read the bios chip in my Dell T3400 (desktop pc) using Flashrom 0.9.4 and 1.2 It detected chipset is Intel ICH9R and then failed. FlashRom 0.9.4 found 2 flash chips AT25DF081A and AT26DF081A then failed to read. But I could see on the mobo only one chip AT26DF081A FlashRom 1.2 failed on Probe/Read while trying Hardware Sequencing. I've attached the logs to this email. Looking at the list of supported chips, I saw that success with this Intel chipset was "config-dependent". So what corrections to get FlashRom to work for my Dell? or What flash utility do you advise so I can get a copy of the bios chip? Thanks for your help, Etonam.
