Was the support software for legacy devices ever published to github, or migrated from the Embedded Micro site?
I pulled my Mojo v2 out of the drawer, but I can’t find any of the support software on the Alchrity website or github. (mojo-loader or whatever it was called, firmware for the atmega16u4, template ISE project or even just the constraints file, etc).
For what it’s worth, the Alchitry Labs V1 software was the direct upgrade of the Mojo IDE/loader. If you’re using ISE directly, probably doesn’t make much of a difference.
