All of these three are interchangeable so I guess someone swapped it without telling you :) In any case you should not use the -c parameter unless you have to and really know what chip is on there. Without it flashrom will find the right chip itself if it can. -- Kind regards/Mit freundlichen Grüßen, Stefan Tauner

Issue programming SPI flash
by Steve Burks 21 Sep '16

21 Sep '16

Hi, I have been flashing Macronix SPI with device ID MX25L12805D. We now have a new Numonyx SPI with device ID N25Q128..3E. However, when I try to flash the device it says that no flash device was found. But when I do the -p internal it clearly shows the device ID N25Q128..3E I have attached the verbose output from when I ran the command. I appreciate any assistance that you can provide. Thank you.

testing my A7V333
by Elmar Stellnberger 17 Sep '16

17 Sep '16

Today I have also tested my A7V333 mainboard with the latest flashrom from svn; and see it could read an image (log in the attachement). It said that write and erase would still need to be tested; however the following message does not raise my confidence: Changing lock bits failed at 0xb7305002! New value: 0xff. Basically I would also be ready to test erase & write on this board though it would likely be a good idea to have the error/log messages checked first.

Unable to detect SPI-Flash connected to RT5350 using flashrom.
by Pradeep Ch 17 Sep '16

17 Sep '16

We are using flashrom tool to program SPI flash on a RT5350 chipset board. We are able to program if we directly connect Jtag to the SPI -Serial Flash. The RT5350 has a Jtag interface pins. Can we connect a Jtag connector to connect to this interface and program SPI-Serial flash using flashrom. Rgds, Pradeep Ch.

W836xx: L372N1 / GC Frontman (flashrom: unknown reg 0x20 ID: ea)
by Elmar Stellnberger 14 Sep '16

Today I have tried flashrom on a rather old L372N1 computer (PIV 2,8Ghz, GC Frontman): ------------------------------------------------------------ flashrom v0.9.7-r1711 on Linux 3.14.50-std460-i586 (i686) flashrom is free software, get the source code at http://www.flashrom.org Calibrating delay loop...

Please send the output of "flashrom -V" to flashrom(a)flashrom.org with W836xx: your board name: flashrom -V as the subject to help us finish support for your Super I/O. Thanks. Found chipset "SiS 645DX". Enabling flash write... OK. No EEPROM/flash device found. Note: flashrom can never write if the flash chip isn't found automatically. ------------------------------------------------------------ The BIOS Chip on the mainboard can be accessed easily; it is placed inside a special hanger and appears to be replacable. There is a sticker on the BIOS Chip saying: 686 AMIBIOS NBEC(c)2000 BA31 8603 installed BIOS: Amibios v1.54, 10/15/2003, Version 1.08G The current BIOS there has some disadvantages like support with old style disks up to a maximum of 160GB (manual Cylinder-Head-Sector configuration); today I have tried it with a 64GB SSD IDE disk and the BIOS can not boot from it ( CD + floppy boot is o.k.). How do you believe are the chances to get flashrom running on that machine or to exchange the BIOS with a newer one? Elmar P.S.: I have attached some more information about the system as I was unsure which one would help you.

[Patch]ignore-read-error
by Tommy.Lo 13 Sep '16

13 Sep '16

Dear Maintainers , This patch is for the following description: Transaction is failed and errors are shown when flashrom try to read region that locked by Intel ME. This patch simply disable code to check error (will read 0xff) then flashrom will continue to read the rest. And only ignore the error when read op. It will output a warning message to stderr like: Transaction (READ) error at address 0x001000-0x7fffff, ignored To avoid a lot of similar error messages, it shows error at end of locked region. Thanks!

flashrom stops/hangs
by joshj23 07 Sep '16

07 Sep '16

while trying to flash a chip (winbond W25Q32.v), on a arduino uno r3, the TX and RX led's will be on while flashrom is running normally, but will almost always turn off and flashrom in the terminal will stop all activity any suggestions? -- *Josh*
