Hi Gordon,
I was using the Chrome Extension, as well as the build from my PR on GitHub. I don't know how long ago the Chrome Extension was updated, but I changed the code upload mode through the settings dialog.
I think the issue was to do with the board running out of flash storage? I had a lot of code on the board at the time, and I only had around 2-3 KB left. I've since made the code much more efficient and ran a
require("Storage").eraseAll();! I discovered the board went into this state when it runs out of RAM or flash (can't tell exactly) whilst uploading a big (> 8 KB) file. I believe that the SELF TEST mode now works correctly now that I've freed the memory!-James.
