Dell XPS 15 9550
by Andrew Warhol 23 Jan '21

Hello, I was wondering if anyone would mind helping me with an issue I'm running into with flashrom on a dell xps 15 9550. The dell has a 16 mbyte Winbond W25Q128.V bios chip on it. I'm using flash rom on a raspberry pi 4 but when I read this chip with a soic8 test clip, it seems to read successfully. However, when checking to see if the checksum of the reads I do are identical, they always come up as different values. The other two bios chips however read with the same checksums every time. I am attempting to use intel me cleaner to set the hap bit and disable intel me without repartitioning or cleaning anything on the chip as intel boot guard is enabled. ME Cleaner is able to read the file and say the hap bit has been successfully set. However, when writing the modified image, I get the error through flash rom verifying flash...failed, your flash chip is in an unknown state. The laptop will no longer boot and the power light comes on for a moment before turning on. I suspect either flash rom is not compatible with this chip or something about this chip prevents it from being read by flash rom. Using this guide: darajnish/dell5577medisable it seems as though a select few people have been able to set the hap bit by using the command soft-disable-only. Even when I try re-flashing the original read bios image however, the laptop still does not boot. I read somewhere that my chip has flash descriptors locked, but since other people have had success I'm not sure why I can't get it to work properly. Any advice would be much appreciated!

Hi all, I would like to see the following feature added to flashrom: https://github.com/flashrom/flashrom/issues/185 If someone implemented it, would the idea (at least) be accepted?

Re: Using libflashrom from fwupd
by Richard Hughes 18 Jan '21

18 Jan '21

On Wed, 16 Aug 2017 at 22:02, David Hendricks <david.hendricks(a)gmail.com> wrote: > The short answer is yes. Nico also briefly mentioned an idea on IRC to use a mechanism similar to flashrom_set_log_callback() to avoid complicating function signatures for the read, write, and verify functions. Dragging up an email thread from a long time ago, apologies. We're finally using libflashrom via fwupd "in production" so to speak. One glaring problem is that the UI "freezes" when we're doing operations with libflashrom, which we've worked around with just making the progress bar spin up and down so at least it looks like the program has not crashed. Of course, the correct thing to do is return the progress information because, as David says, some flash chips take a looong time to write. I've attached a patch for some initial comments, if this looks acceptable I can add some more callbacks in other flash implementations (as at the moment I've only covered SPI stuff) but I didn't want to spend time on a mega patch before I had some kind of initial thumbs-up. Comments welcome. Thanks. Richard.

Flashrom Test Report (+ DOS build)
by Howard Ho 16 Jan '21

16 Jan '21

Hi, I successfully read/wrote a BIOS image file to a MSI Z390-A PRO (MS-7B98) motherboard via both Linux and DOS builds of flashrom based on the master branch on Jan. 1, 2021. Attached are reports/logs. Also, I would like to report that the "buildbot archive" link for finding DOS bulids of flashrom linked on https://flashrom.org/Downloads is not working for me as I am not able to connect to that site (seems like https://buildbot.flashrom.org/ is no longer online). So I built for myself a copy of flashrom for DOS. After making some changes to the code, I was able to cross-compile for DOS on Linux. I used pciutils 3.6.4, which did not require the patch to cross-compile the pciutils library for DOS. I put my build steps as well as my tested PC findings at https://github.com/HowardHo2021/flashrom-DOS-port. Regards, Howard

Opinions on it87spi.c hack to support IT8686E?
by Pete Smith 09 Jan '21

09 Jan '21

Hi, I have a a GIGABYTE GA-H270N-WIFI motherboard with DualBIOS feature. Flashrom 1.2 is unable to select between the two flash chips with dualbiosindex parameter, as the Super I/O chip (ITE IT8686E) is unsupported: "Super I/O ID 0x8686 is not on the list of flash-capable controllers." In a naive attempt, I just tried to add the chip ID to the list: --- a/it87spi.c +++ b/it87spi.c @@ -256,6 +256,7 @@ int init_superio_ite(void) case 0x8718: case 0x8720: case 0x8728: + case 0x8686: ret |= it87spi_probe(superios[i].port); break; default: This modification made flashrom able to select between the flash chips: # flashrom -p internal:dualbiosindex= DualBIOS: Selected chip: 0 # flashrom -p internal:dualbiosindex=1 DualBIOS: Selected chip: 1 # flashrom -p internal:dualbiosindex= DualBIOS: Selected chip: 1 Reading the flash content also seems to work: # flashrom -p internal:dualbiosindex=0 -r M_BIOS.bin Enabling flash write... SPI Configuration is locked down. Enabling hardware sequencing because some important opcode is locked. OK. DualBIOS: Selected chip: 0 Found Programmer flash chip "Opaque flash chip" (16384 kB, Programmer-specific) mapped at physical address 0x0000000000000000. Reading flash... done. # flashrom -p internal:dualbiosindex=1 -r B_BIOS.bin Enabling flash write... SPI Configuration is locked down. Enabling hardware sequencing because some important opcode is locked. OK. DualBIOS: Selected chip: 1 Found Programmer flash chip "Opaque flash chip" (16384 kB, Programmer-specific) mapped at physical address 0x0000000000000000. Reading flash... done. Comparing the two firmware dumps, I find the only difference is that M_BIOS.bin contains my current BIOS settings which B_BIOS.bin does not, so I'm quite sure that these dumps are actually from two different flash chips. However, if enabling verbose (-VV) output while reading flash, I also see this message, which I don't know if normal or not: "No IT87* serial flash segment enabled." I have not yet tried writing to any of the flash chips, as I would really appreciate if someone with more experience than me could comment on this modification first, and maybe highlight problems I'm not currently aware of? Thanks in advance. Best regards, Pete Smith

chipset Intel C226 is marked as untested
by Philippe Lefèvre 07 Jan '21

07 Jan '21

Hello, just curious about my ROM, I used flashrom to see what is in and would like, why not, replace it by a coreboot version, and let you know. It seems that it wouldn't work as enable flash write seems not working. My box is a DELL Precision T1700 Here is what I get : flashrom v0.9.9-r1954 on Linux 4.9.0-14-amd64 (x86_64) flashrom is free software, get the source code at https://flashrom.org Calibrating delay loop... OK. Found chipset "Intel C226". This chipset is marked as untested. If you are using an up-to-date version of flashrom *and* were (not) able to successfully update your firmware with it, then please email a report to flashrom(a)flashrom.org including a verbose (-V) log. Thank you! Enabling flash write... Error accessing ICH RCRB, 0x4000 bytes at 0x00000000fed1c000 /dev/mem mmap failed: Operation not permitted FAILED! FATAL ERROR! Error: Programmer initialization failed. Hope this can help Regards
