Thinkpad T420
by aadu＠airmail.cc 17 Mar '18

17 Mar '18

Hello I was trying to flash BIOS of Thinkpad T420 for my project when I noticed that version 1.0 of flashrom doesn't support it. From coreboot wiki I understood that it was supported at some point. Is there a way to bypass this or does older version of flashrom support it? Aadu

If you can flash internally from an OS depends mostly on the configu- ration of the chipset done by the BIOS. Likely only possible if there is an explicit option in the BIOS setup to disable flash protections. You can always try to run flashrom to see the actual configuration. Though, for mobile devices it needs an ugly switch (have a look for `force_I_want_a_brick` in the flashrom manual page). That switch sounds scary because older laptops really had problems, even if you only probed the flash chip. It's not that dangerous on a modern sys- tem. The alternative is to access the flash chip physically, like Mike described. If you get access to the flash chip, you'll also need a valid BIOS file (not just an update). > Starting from surface pro4 Chip is manufactured by Microsoft. What chip? never heard that Microsoft would manufacture chips. Nico

GD25Q128C write success
by Tomasz Walach 16 Mar '18

16 Mar '18

Hello, I have tried to recover my IP camera with flashrom and PI after I erased all memory. I think my successful reading writing and verifying of an image which I used might prove that this chip 25Q128CSIG is supported. As an attachment, I am adding 2 pictures of the camera and an output of log after writing procedure. If you need something more to test on this chip please let me know. Thank you very much for developing and allowing flashrom to be used by anyone. Without it, I had to find another way to write the image. At least by confirming the successful result, I will contribute this way in future development. Regards, Tomasz

[PATCH] Fix compilation with older MinGW versions
by Antonio Ospite 13 Mar '18

13 Mar '18

The __MINGW_PRINTF_FORMAT constant has been defined back in 2012 https://sourceforge.net/p/mingw-w64/mingw-w64/ci/77bc5d6103b5fb9f59fbddab15… However older toolchains are still around and some user reported the following compilation failure: flash.h:336:1: error: '__MINGW_PRINTF_FORMAT' is an unrecognized format function type [-Werror=format=] __attribute__((format(__MINGW_PRINTF_FORMAT, 2, 3))); Fix this by defining the constant when it isn't already; the change does not affect other compilers because it's guarded by "#ifdef __MINGW32__". Setting __MINGW_PRINTF_FORMAT to gnu_printf is exactly what newer MinGW versions do when __USE_MINGW_ANSI_STDIO is defined, which it is in flashrom Makefile.

What am I missing? the circuitry of your hard drive is most likely not prepared for powe- ring the flash chip directly at its VCC pin. You probably power all 3V3 parts on that PCB which is too much for your RPi's PSU / voltage conver- ter. Killing the SPI flash is unlikely. I can't say the same about other chips on the board, though. Reading the flash while the hard drive is up and running, probably also isn't a good idea. You could desolder the flash chip, or try a stronger PSU, both ways have chances to break some- thing. Nico

AFAICS (from following the code in chipset_enable.c), PIIX4 doesn't support SPI at all. Only parallel flash chips. And these work much differently. `flash->mst` gets set in probe_flash(). It's just the programmer you select on the command line. For the `internal` programmer this is hard to follow, though. In chipset_enable(), it's decided what that master `mst` actually can do for a given chipset, mostly based on the PCI id list in `chipset_enables`. > Does > flashrom read and write to hardware registers? Thank-you so much! Yes, it does. In case of internal SPI controllers, it pokes registers of that controller. In case of internal parallel flash chips, it seems to directly access memory mapped registers of the flash chip. For the latter have a look at jedec.c and the functions at the end of `internal.c`. Hope that helps, Nico

Flashing iPXE on Intel i210 on Supermicro X11SSL-F

Dear list, I'm curious to know if it is possible to flash iPXE to these nics. PCI-Id is listed in supported devices - 8086:1533 .

Found Programmer flash chip "Opaque flash chip" (4 kB, Programmer-specific) on nicintel_eeprom. No operations were specified. When i build a rom for this specific nic the file has a size of 70kB.

Of all the gin joints in all the towns in all the world, Alex Henderson had to walk into mine at 09:08 on Tuesday 06 March 2018 and say: > Vadim: > Usually programming the firmware ROMs for Intel NICs requires software > from Intel. > https://www.intel.com/content/www/us/en/support/articles/000005790/softwar > e/manageability-products.html may do the trick. Alex Yeah, except Intel's tools only support ROM images generated by Intel and stored in their magic file format. You can't use them to flash your own custom images. You can only do that with flashrom. :) The problem here is that flashrom has to know the flash programming interface used on the NIC, and sadly they aren't all the same. When I tried it, I used an 82574L card. At the time it was not supported. However, the 82574 uses the same programming interface as the 82571, which _was_ supported, so making it work was just a matter of adding the 82574's device ID to the right table in flashrom. You can attempt to do the same thing with the i210, but I don't know offhand if that will work. If it doesn't, then you'll have to download the programming manual for the i210 and add a new programming algorithm to flashrom. -Bill > -----Original Message----- > From: flashrom [mailto:flashrom-bounces@flashrom.org] On Behalf Of Vadim > Bulst Sent: Tuesday, March 6, 2018 12:51 AM > To: flashrom(a)flashrom.org > Subject: [flashrom] Flashing iPXE on Intel i210 on Supermicro X11SSL-F > > Dear list, > > I'm curious to know if it is possible to flash iPXE to these nics. > PCI-Id is listed in supported devices - 8086:1533 . > > [root@urzospoc01 src]# flashrom -p nicintel_eeprom:pci=01:00.0 flashrom > v1.0 on Linux 3.10.0-693.17.1.el7.x86_64 (x86_64) flashrom is free > software, get the source code at https://flashrom.org > > Using clock_gettime for delay loops (clk_id: 1, resolution: 1ns). > Found Programmer flash chip "Opaque flash chip" (4 kB, > Programmer-specific) on nicintel_eeprom. > No operations were specified. > > When i build a rom for this specific nic the file has a size of 70kB. > > Is there a way to get this rom to the nics? > > Cheers, > > Vadim > > -- > Vadim Bulst > > Universität Leipzig / URZ > 04109 Leipzig, Augustusplatz 10 > > phone: +49-341-97-33380 > mail: vadim.bulst(a)uni-leipzig.de > > > _______________________________________________ > flashrom mailing list > flashrom(a)flashrom.org > https://mail.coreboot.org/mailman/listinfo/flashrom -- ============================================================================= -Bill Paul (510) 749-2329 | Senior Member of Technical Staff, wpaul(a)windriver.com | Master of Unix-Fu - Wind River Systems ============================================================================= "I put a dollar in a change machine.

Thanks Alex and I've tried BootUtil - but no luck. I've read the discription of BootUtil thanks to your link and found an important article: " * BootUtil is not intended as a utility for LAN-On-Motherboard (LOM) implementations. Adjustments made to BootROM settings on LOM implementations may not affect how the adapter operates. " And well this nic which i was trying to flash is a LOM. So i guess there will be no chance to flash it.

Some troubles connecting a W25X40ALSNIG flash chip to raspberry pi (v3 model B)
by Jesse Li 06 Mar '18

06 Mar '18

Hey, I'm trying to read from and flash to a W25X40ALSNIG [0] that's still mounted to its hard drive PCB. Following the table from the raspberry pi wiki page [1], and assuming the raspberry pi pin numbers it mentions are physical pin numbers (and not the pi's strange GPIO numbering scheme) I connected the legs of the flash chip to the raspberry pi's GPIO pins. However, when the two are attached, the pi won't boot (it'll show the three raspberries in the corner, then it shuts off). I've isolated this to the VCC (connected to header 17, 3v3) and GND (connected to header 25, GND) , where having all of the legs of the flash chip detached from the pi except for those two will reproduce my problem (I hope testing that didn't actually kill the chip).
