Dear Coreboot team,
The installation instructions for Lenovo ThinkPad T470s/T480/T480s/T580/X280
say:
> The T480 (but not T480s) supports the use of the EC UART for debugging. If
> you want to use this feature, you need to downgrade the vendor firmware to a
> version with a compatible EC firmware before flashing for the EC UART to work
> properly. The EC firmware version needs to be 1.22 (N24HT37W), which means
> any BIOS from 1.39 (N24ET64W) to 1.54 (N24ET79W) is acceptable.
Is the recommendation for T580 similar? If so, which BIOS version should I
change to? The list of versions for T580 is very different, see
https://pcsupport.lenovo.com/us/en/products/laptops-and-netbooks/thinkpad-t-series-laptops/thinkpad-t580-type-20l9-20la/downloads/ds502394
In the future, it would be great to add information on this issue to the
instructions.
