Seems the WIKI was put together in a hurry and lacks a lot of common/simple details.
For example based on this page it lacks simple common details for users to figure out how to boot of different devices.
https://espressobin.net/mochabin_wiki/tiki-index.php?page=Jumpers+Setup
None state how to boot from USB thumbnail.
Please put effort into proper and detailed documentation that is understandable. The device is pretty much a paperweight without good documentation!
