I've seen #400 PR but I went ahead and modified the docs to use the new suggested template (https://github.com/knurling-rs/app-template).
The tricky part is that the new template uses
defmt, so theqemu-system-armbinary is not enough but Ferrous System'sqemu-runtool is required to decode the output properly.I'm not a big fan of third-party dependencies in the official docs, but feedback is welcome.
