I was doing some troubleshooting yesterday and found that the download option from the ellipse submenu on the drivers code page doesn't seem to be working. This is needed when using Libraries to standardize code across multiple drivers so we can see exactly what is included in a driver from the libraries and on what line for troubleshooting.
This is not just a problem for drivers with libraries as it appears it doesn't work for drivers that don't use libraries either.
For what it's worth, Me Too.
I have the same issue with 'Download' option not working to debug device code with included libraries. My temporary workaround is to manually add all library code in the app or device driver at the bottom and comment out the library include statement(s). (Ugh).
I am coding on MacBook Pro M4, macos 15.3, various tested browsers (Brave, Chrome, Safari, DuckDuckGo).
For me, this is a good time to take a short break from developing complex custom drivers for HE.
I happen to know that @gopher.ny hates it when you are laying about lazily, and will get to this ASAP.
