Date: Wed, 4 Feb 2026 14:29:22 +0100 From: Ivan Colavito <ivan.colavito@gmail.com> Reply-To: ivan.colavito@gmail.com To: flashprog@flashprog.org Good morning, I have a TopTon X2E motherboard with an N150 CPU whose Libreboot support has just been added. The internal flash of the Libreboot firmware using flashprog succeeded (flashprog wrote VERIFIED), but the PC no longer turns on (black screen and status LEDs on). I’m trying to flash the original factory firmware back, but flashprog won’t cooperate: it tries to read the contents of the EPROM but then freezes without giving errors, and it doesn’t produce any dump. I’m attaching the log file (created with -VV). I’ll add that the motherboard shows this serial number: BK-1264NP-4L-45G25***** and that the EPROM chip has this marking: FM25W128 2526I2G, which should correspond to the specifications document that I’m attaching. Flashprog says it doesn’t recognize it, but the basic operations should work anyway… so what could the problem be? How can I convince it to perform the flash? I’m using a Raspberry Pi Pico H with the flashser firmware provided by Libreboot for version 26.01 (just released and compatible with my motherboard) loaded onto it. Thank you very much!
