[tlaurion]

might impact v540tu and v560tu as well

[filipleple]

I cannot reproduce the issue building from the release tag from our repo. It seems to be an issue with the CI rather than our code.

V560TU:

@filipleple its from downloaded releases binaries

[tlaurion]

Users only find rom files not zip files to upgrade from with their dpp credentials.

[BeataZdunczyk]

Thanks for the report. We will update our release process to the new Heads requirements, and going forward, .zip files will be part of every DPP Dasharo (coreboot + Heads) release. We are adding .zip files (rom + sha256sum.txt) alongside the existing files on MinIO for:

• v0.9.3 NovaCustom NV4xPZ (ADL)
• v0.9.1 V540TU / V560TU (MTL)

[filipleple]

.zip's have been uploaded.

[tlaurion]

• v1.0.1 V540TU / V560TU (MTL)

For posterity (and validation) it's v0.9.1 for V560TU/V540tu, not v1.0.1 (which are dasharo+uefi)
