EC firmware for MSI B660-A DDR4

[kamil.uhlir]

Hi all,

I probably need a firmware dump for the Nuvoton NCT6687D‑M controller (EC flash chip: W25X20CLNIG) used on the MSI B660-A DDR4 (MS‑7059, revision 1.0). I bought PC with partialy working motherboard. Computer POST´s and after a long time show BIOS screen. No temperatures, no FAN speed, no voltages showing. After selection of the BOOT override starts boot. This procedure repeats each start. EC version in BIOS is 000000.0.

I tried to read content of the W25X20CLNIG chip and seems empty.

Does anyone have appropriate dump?

Many thans.

Kamil
