I’m working on a relatively new Dell Latitude 5440, Intel i5 model, and I’m trying to make clean backups of the onboard SPI flash chips without desoldering, if possible.
The motherboard has two Winbond SPI flash ICs close to each other:
- UC2: Winbond 25Q256JVEN, likely 32 MB
- UC6: Winbond 25R128JVSN, appears to be 16 MB
I’m using a CH341A programmer with a SOIC8 clip on Linux.
Tools tested:
- flashrom on Linux
- IMSProg GUI on Linux
With flashrom, UC6 is sometimes detected...
