Heh, I missed this (your other mail went into another folder). So you can ignore my other mail, I guess. Though, if you want to try a patch for the error you've seen before, let me know :) Nico

PC is power on. Try to verify (flashrom -v) the image you just wrote. I hope it just succeeded but run into an error afterwards. >From your log: >> 0x805000-0x805fff:E >> Request to erase some inaccessible memory address(es) (addr=0x805000, len=4096). Not erasing anything. This is already beyond your actual flash chip (0x800000), so it al- ready wrote the image. I also found the cause for flashrom running off, your firmware descriptor seems misconfigured which triggered a bug in flashrom: >> 0xD0: 0xffffffff (FPB) This register is supposed to be 0 instead *shrug*. But there's obviously something to fix in flashrom to handle wrong values more gracefully. So, hope your board is fine, Nico

Hello, 1) save image - flashrom -p internal:laptop=force_I_want_a_brick,ich_spi_mode=auto -r boxpc899_0.rom 2) write image - flashrom -p internal:laptop=force_I_want_a_brick,ich_spi_mode=auto -w boxpc899_0.rom -V -o /lib/live/mount/medium/ I have tried to write saved image finally. And got the following message: FAILED! Uh oh. Erase/write failed. Checking if anything has changed. Reading current flash chip contents... Reading 8388608 bytes starting at 0x000000. done.

Hello Paweł, sorry for the late reaction, your message was filtered due to its excessive size (we have a 256KiB limit). On 30.06.2018 10:33, Paweł wrote: > Thanks for answer.

To check I also pulled W25Q32.V from working Asus P8B WS and was > able to correctly read bios several times with spispeed 1000,10000,20000. > Checksum was correct. Generally you'd want shorter connections. As you use a breadboard, you shouldn't need all the long wires, only those from the RPi to the bread- board. That it works with one chip is no proof that the signals are good enough. Also, not clearly visible in your picture, it doesn't look like you connect all input pins of the flash chip. If that is the case: You should always connect all of them, they need a defined state, no matter if you use their function (if in doubt, pull them high to VCC). Hope that helps (or you succeeded already), Nico

S25FL512S Chip Support

Hi guys, Does flashrom currently support the S25FL512S/Sf25FS512S? I don't see it on your supported devices list but see many similar spansion chips.

HP WX9400 Workstation Mainboard flash
by Joel I. Oelsner 08 Aug '18

08 Aug '18

Hello, I've bought a HP wx9400 workstationboard - In acutallity it's a Tyan S2915-E. So my problem is: HP have flashed a special hp bios and pflash from Phoenix does not allow you to flash the vanilla tyan bios. The board has a SST49LF080A chip, so in theory flashrom should work - would be my guess. So my question is: do I just rom flashrom -p internal -w s2915.rom?, or is there anything else I have to do before flashing a phoenix bios(except a backup). furthermore I don't think the mainboard chipset is not supported - the chipset is a NVIDIA NFP3600 / NFP3050 . best regards

MX25L6473E

Hi, I'm French guy and i have a problem with my motherboard. After MAJ bios failed on my MSI-Z87-G45, i have search to the web for solution and i've find : CH341A With Flashrom. I buy CH341A Black Edition with Cable Clip SOIC 8, In order not to have to desolder the chip. Check Ubuntu 18.04 on Laptop = ok Check install flashrom (sudo apt-get install flasrom) = ok Check install https://github.com/gschorcht/spi-ch341-usb = ok Then, in general didn't work > Flashrom can never write if the flash chip isn't found automatically. But it worked twice and here is the message : Calibrating delay loop ... OK. Found Generic flash chip "unknown SPI chip (RDID)" (0 kB, SPI) on ch341a_spi. === This flash part has status NOT WORKING for operations: PROBE READ ERASE WRITE ...bla bla bla .... Read is not working on this chip. Abording Ok now, that is my chip : MXIC MX25L6473E M2I-10G 3P261900 L13511S Something missing on my linux distribution? (drivers configuration ...) I need your help or advices. Thanks Emmanuel PS : Sorry, my English so bad.

If you provide a verbose log for this board, we might be able to tell you more. For instance, newer systems with the BIOS flash con- nected through SPI to the southbridge or almost always safe to flash (you can see in the manpage how to tell flashrom that your board is not a laptop, or that it should flash anyway). Hope that helps, Nico
