*: Some devices appear to have two firmware entries, ?.firmware and ?_AssistMode.firmware.

None? (X390 has version 20, but nothing for X390 Yoga) None? (X380 has version 20, but nothing for X380 Yoga) Do the fwupd developers have to deal with this, or is it something that Lenovo provides when they add firmware to LVFS?

What, if anything, should be done to ensure that the firmware images can be properly flashed on each device.

Can we get firmware images for all of the remaining devices onto LVFS.

So I guess there's two things I'm interested in tracking here: This may damage the firmware.' ( )Īs well as notes from Lenovo about needing to update the driver before updating the firmware (at least on Windows).Īll of these things lead me to believe that we might need more than just the raw firmware image, and that the update process may need additional work and/or testing. I also noticed this issue: fwupd/fwupd#1676Īnd this comment: 'DO NOT FORCE UPDATE Thunderbolt Controller. Have we not been updating Thunderbolt firmware until now? Maybe it didn't seem like there was a compelling reason to do so.? There were one or two cases where LVFS had a version released a month or two earlier, but none that were really old. I noticed that for each of the affected machines, LVFS either has Thunderbolt firmware version 20 / 43 (the version that fixes the bug), or no Thunderbolt firmware at all.

Is the process of writing the firmware image to the correct location dramatically different on different machine types? haphazardly populated for a bug that can allegedly brick a machine, especially since Lenovo already has Windows utilities to update the firmware on each of the affected machine types. I have more experience with embedded device firmware than PC firmware, so apologies if this comes off as naive: This table seems. The table below is a summary of firmware availability for affected machines on LVFS, as of. Failure of this ROM can apparently cause error messages, Thunderbolt chipset failure, or even boot delay / failure. It's not clear what the actual problem is, but some of the individual updates mentioned 'ROM wear out,' so it might be related to excessive writes to flash somewhere.
