New-Bee Observations

Throughout my code development, I have noticed some strange quirks when uploading new code to the Espruino.

Observation 1
If there was a "large" amount of code revisions, from the previous upload, after hitting the reset() and upload in the IDE, the computer does not display the progress bar until it thinks what it should be doing. In some cases, 5 to 10 seconds can elapse until the progress bar is displayed for the user.
For a novice, like me, this delay without the progress bar showing, I would constantly send a reset to the Espruino. The progress bar should be shown immediately after the reset.

Observation 2
Patching and making "large" new user code (using BigRam v70) the Espruino hangs at boot time. The trick I used was to "piecemeal" and upload "small" sections of code with no "boot hangs" until all the code was done.

Note: This is the same problem I had previous going from v69 to v70 BigRam. What I did was to re-write an algorithm and the problem seemed to disappear?

Below could be the culprit - could be wrong? ...

Just to add that if you flash these, Espruino will start remembering
the code that you saved between firmware updates. If I've changed the
way data is stored internally then it can cause Espruino to hang at
boot time.

To fix it, just press reset, and hold down BTN1 for a few seconds
immediately after releasing reset (but not before or you'll enter
bootloader mode with the pulsing blue LED).

BTW ... Fixed your spellguard so it doesn't flag Espruino as mis-spelled.
