I have pushed my current patch set for the CH341A to my github repo: https://github.com/stefanct/flashrom/tree/ch341a I have forgotten what does not work yet, and the code itself is definitely not in good shape yet either but feel free to hack away on it :) -- Kind regards/Mit freundlichen Grüßen, Stefan Tauner

SST39VF040 on 3COM 3C905C:
by Xavier Bourgeois 30 Sep '15

30 Sep '15

The SST39VF040 is listed as untested on the flashrom supported hardware page. I tried it on a 3Com 3C905C (which limits to 128kbytes). All operations (probe, read, erase and write were done successfully for the first 128kbytes) [0]. I attached the NIC's bootrom [1], which was resized from 64kbytes to 512kbytes in order to be flashed. I also attached the same image which has been read after the flash. All the first 128kbytes are identical, and the data repeats until the end of the file. The network card is also able to boot from this eeprom. Thanks, [0]: http://monorailc.at/tmp/3c905c.tar.gz [1]: http://monorailc.at/tmp/3c905c_dump.tar.gz -- Xavier Bourgeois

Nope, there isn't, at least nothing that I know about or that will hit vanilla flashrom soon. -- Kind regards/Mit freundlichen Grüßen, Stefan Tauner

FS Esprimo E5730: reading rom does not seem to work if BIOS write protection is enabled
by Elmar Stellnberger 15 Sep '15

15 Sep '15

Today I have tried to read the BIOS image of my Fujitsu Siemens Esprimo E5730. flashrom has complained about the write protection as being set in force manually by the BIOS settings although I have just tried to read an image: > flashrom -p internal:ich_spi_mode=auto --read test.rom flashrom v0.9.7-r1711 on Linux 3.14.50-std460-amd64 (x86_64) flashrom is free software, get the source code at http://www.flashrom.org Calibrating delay loop... OK. Found chipset "Intel ICH10D". Enabling flash write... FREG0: Warning: Flash Descriptor region (0x00000000-0x00000fff) is read-only. FREG2: Warning: Management Engine region (0x00003000-0x002f7fff) is locked. Not all flash regions are freely accessible by flashrom. This is most likely due to an active ME. Please see http://flashrom.org/ME for details. Writes have been disabled for safety reasons. You can enforce write support with the ich_spi_force programmer option, but you will most likely harm your hardware! If you force flashrom you will get no support if something breaks. On a few mainboards it is possible to enable write access by setting a jumper (see its documentation or the board itself). OK.

If you are running the latest development version, please email a report to flashrom(a)flashrom.org if any of the above operations work correctly for you with this flash part. Please include the flashrom output with the additional -V option for all operations you tested (-V, -Vr, -VE, -Vw), and mention which mainboard or programmer you tested.

MX25L25635E / 4 byte addressing
by Peter Martini 15 Sep '15

15 Sep '15

Hello, I've checked out master from the flashrom svn repo, compiled, and was able to see my chip (MX25L25635E). The id wasn't recognized, but after a quick patch to copy a MX25L128... to ..L256.., I got it to successfully read the first 16MB of the chip - however, I can't get any further than that, because changing the values in the table to the right values moves me from 3 byte addressing to 4 byte addressing territory (if I understand this correctly), and it looks like there aren't any patches merged for that yet. Is there a patch set actively in the works? (I saw some activity around this from January, from this link http://patchwork.coreboot.org/patch/4272/, but I'm not sure where that ended up). Thanks! Peter

The only thing is that it requires the creation of an extra file and I tend to find that it's not always convenient to have to create files for known patterns. However I think that it would be possible based on your approach to provide an option to replace the file with a known pattern for some cases (eg: full of 0xff or full of 0x00, which could be called "assume-clean" or "assume-dirty"), which would achieve the same result and at the same time not change the spirit of your latest work. Best regards, Willy
