2019-08-15 Thread Mike Banon
I'm sure that, if your motherboard has a single flash chip or you have removed this chip and plugged it into a programmer, flashrom -r should backup the whole contents of a chip regardless of its' internal memory map. But I don't know if this is true for all the possible cases for the boards with t

What is your BPv4 bootloader version? I've tried many builds of BPv4 community firmware, the latest is from 12 June 2018 sources (didn't feel the need to upgrade it later) and never had any problem with flashrom. However, my firmware builds have been always paired with the latest builds of BPv4 boo

"I have flashed the bios to a new version" - how you did that, using a windows tool provided by a laptop manufacturer? If yes, then it preserves the originally set password and maybe the other settings. Try to extract a "clean" BIOS image from the BIOS update utility provided by a laptop manufactur

Please note that a BIOS upgrade utility provided by your board manufacturer - might be upgrading more things than just a BIOS. For example: EC firmware for a controller which i.e. may be adjusting the fan speeds depending on a temperature. As you see, simply upgrading a BIOS via flashrom may leave

It's known that flashrom internal flashing may be working or not working depending on a platform. For example, laptops EC controller might interfere with the internal flashing attempt, causing it to fail. Do you have a physical access to this server? If yes, could you use some external flashrom-sup

Good day! flashrom source code is open, so you could check how the support for already-supported-by-flashrom GigaDevice chips has been added, and try to do something similar - following the Development Guidelines from a flashrom wiki here : https://www.flashrom.org/Development_Guidelines . Best re

The device names are different on MacOS than Linux. /dev/tty.usbmodem is correct for CTC devices. I did finally settle on community firmware 7.1 without any optimization. That works with flashrom and doesn’t require being reset after every invocation of flashrom. I haven’t upgraded the boo

You need to extract a clean BIOS ROM ( "clean" = without any system-specific settings ) from a BIOS update utility. Try to open this utility (called something like "winflash_3.00.exe") as an archive with 7zip, and extract the contents of this .exe file using 7zip. If successful, it would give you a
