Subject: Flashprog freezes during reading.

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!
Ivan
