Hi, 

i have just successfully been able to flash the W25Q128.W chip.

Bricked Motherboard: UP2 Squared (Link below)

Mainboard for flashing: Raspberry Pi 3B

OS: Raspbian Buster Lite.

Flashrom version: Linux 4.19.118v7+ (armv7l) 

I am new to using flashrom, so email me back if i have given you the wrong log file and you are in need of the right one.

Best regards,
