STSTM32 - Could not find the package with 'platformio/tool-dfuutil @ ~1.9.190708' requirements for your system 'linux_aarch64'

Hmm I was under the impression that Rosetta would take care of this. Definitely file an issue about that.

When you open a new issue in platform-ststm32 you can just drag-and-drop your file into the comment text and it’ll upload.
