Possible to boot raspberry pi 4 from an external USB?

Glad you are sorted out ! and as said the feedback is valuable :+1:

No it’s fine here, you may give the extra tag arm:

This triggers the arm team to have an look, and others know it may be arm specific.

Could you mark the write-up form my (poor) memory as the solution of the topic, after all it did get the RPI4 booting from the USB dive :slight_smile:
