Hi. Recently i have experienced problems with flashi bios in broken NAS server. Flahrom was able to detect the chip but couldn't do anything with it. Below is the output from the tool. Can you help me somehow or direct me the way to find solutuon myself?
Thanks!
Found Winbond flash chip "W25Q64.W" (8192 kB, SPI). This chip may contain one-time programmable memory. flashrom cannot read and may never be able to write it, hence it may not be able to completely clone the contents of this chip (see man page for details). Erasing and writing flash chip... Trying erase function 0... 0x000000-0x000fff:EFAILED at 0x00000000! Expected=0xff, Found=0x00, failed byte count from 0x00000000-0x00000fff: 0x1000 ERASE FAILED!

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-supported programmer, something like CH341A, with a (SOIC8 ?) test clip to attach to a BIOS chip without any soldering? Check these articles: https://www.flashrom.org/ISP , http://dangerousprototypes.com/docs/Flashing_a_BIOS_chip_with_Bus_Pirate (last part of this article describes the process for CH341A)
