I should find a morello linux img file in
build/tmp-soc/deploy/images/morello-soc but... it's not there. Been
trying to find out why... so far no luck:

Thank you for pointing this out, we will update the blogpost, however
the article should not be treated as a manual. That branch had quite a few
updates since the article was written.

The only official manual is within the README.md files [1] [2]

As Ross pointed out, indeed *.wic files are the usb disk image, so please do use the usb-image-morello-soc.wic

@  6:48PM ~/w/morello/meta-morello 🌱 release-1.5 🔥 2506480

NB: there is a 1.6 release available.

If you find any issues please do let us know.
