Debug Builds and the Debug Console

A Debug Build is the same firmware plus a Debug Console: the serial console, over Wi-Fi, behind a token. It is the most useful thing in the project. With it you can:

• see everything the device prints, boot messages included, without a cable;
• run every serial command from your desk;
• press keys and take screenshots, so a UI change can be tested and looked at remotely;
• copy files to and from the SD card;
• read crash reports and fetch core dumps, decoded against the exact build that crashed;
• update the firmware over the same Wi-Fi, and know that a bad update rolls back to a build that still has the console.

Start with Debug Builds to put one on a device, then the Debug Console. The rest are what you can do with it.
