I was getting intermittent update errors. It would complete updating but then would not connect, and display continuous

type of errors on the dev console.

However, they could have been due to undetermined status of the board firmware prior to the update.

I loaded good FW from Command window, then re-initiated the update through microBlocks and it all worked OK.

If you think there could be another issue, I can retry using an older FW and then update it.

It sounds like you may not have had MicroBlocks firmware installed on that board? Once the serial port is open, you should be able to install the MicroBlocks firmware even though the green indicator is not lit.

Another possible cause: if the firmware update fails partway through it causes ESP boards to crash repeatedly when they try to start. Again, reinstalling the firmware should fix that problem.

I just tested this in the browser in 0.6.8 by escaping out of the firmware install for an ESP8266 board. That caused the board to be disconnected and errors to appear in the developer console, but when I selected “update firmware on board” and allowed the install process to run to completion, it recovered and reconnected to the board.

Basically, if anything goes wrong with firmware installation on an ESP board, retrying may fix things.
