Hello. Today I try to flash BIOS on my motherboard to support NVMe devices and get terrible message in log "DO NOT REBOOT OR POWEROFF!" After reading BIOS again I saw that flash contents is not changed. Is it safe to reboot my PC now? Can you suggest how can I flash my BIOS? You can see read and write logs in attachment. Best regards, Lyubomyr

Okay, I'm seeing it better now and it isn't removing the block protection.

Varification trouble - flashrom v0.9.9-r1954, Intel I210 NIC over SPI, Microchip SST25VF040B
by Lamont Dean 12 Dec '17

Hello, Flashrom can find the Intel I210 NIC SPI connected to the SST25VF040B flash chip and seems to program but fails to verify and gave me this email to write to about it. The output is included below. Before and after a power cycle the Intel I210 still says its in its unprogrammed state. I'd like to program a Microchip SST26VF016B flash in place of the ...25VF040... but its not on the list so I'm going through the comments I found on the wedsite Design Guide <https://www.flashrom.org/Development_Guidelines>. I'm new to Linux and things so we'll see how it goes. Any help you can offer would be greatly appreciated.

Good morning I have a "W25Q128.V" chip on my board and i made a backup off the old boot. I have try to inject the new one but no luck at all. I have this error message appear.

Laptops, notebooks and netbooks are difficult to support and we recommend to use the vendor flashing utility. The embedded controller (EC) in these machines often interacts badly with flashing.

Likely, those things are set in the control register, but I don't know the exact meaning of the bits. Also, some status bits are checked in the same register to make sure that the operation is completed. I can make some guesses, but I'd rather find documentation if possible. Meanwhile, I also looked at Linux drivers and this one seems to be somewhat similar but still different: http://elixir.free-electrons.com/linux/latest/source/drivers/spi/spi-falcon… See SFCMD / SFADDR / SFDATA. -- Andriy Gapon

particular spi flash controller
by Andriy Gapon 01 Dec '17

01 Dec '17

Hello. I wonder if anyone here encountered an SPI flash controller (master) that has a three register interface where the first register is used for control and status bits, the second register is used for setting a flash address (if one is needed) and the third is used for reading or writing the flash data. A specific operation is requested by writing an SPI opcode into the control register. The interface seems to be rather simple, but I couldn't find any driver that implements access to anything like that or any documentation that would describe a similar interface. Does it sound familiar to anyone? Could anyone give me some hints / pointers? Thanks! -- Andriy Gapon
