OctoPrint - Firmware update stuck?

This is mildly terrifying... OctoPrint is displaying "Starting Flash" but is stuck there. I am first and foremost furious that this stupid thing doesn't have a TIMEOUT function, but that is an Octoprint problem and not a Prusa problem.

I have a Prusa i3 MK3. I am trying to load 3.3.1 and this is my first attempt at updating the firmware since I received the printer.

First off: Is it safe for me to turn anything off to troubleshoot? It does not appear to be flashing... the printer LCD screen has not changed and the log file does not appear to have connected/started loading.

Second off: What is going wrong here? Some config/log info below:

FirmwareUpdate Config:
Path to avrdude: /usr/bin/avrdude
AVR MCU Type: ATmega2560
AVR Programmer Type: wiring
(I also set the baud rate to 115200 which seems to be the normal setting that works for Octoprint... Auto would fail)

So in my novice experience here... It looks like it keeps trying to connect, timing out, and repeating the process? My normal Octoprint IP address is 192.168.1.5 so I don't quite understand why it is using .11 for the firmware or if that is an issue or not.

Any ideas how to fix this? Thanks for any help.

Re: OctoPrint - Firmware update stuck?

I have the same behaviour!
Printer i3MK3 Firmware version 3.4.0
Octopi 0.14.0 on RPI Zero W
Octoprint 1.3.9
avrdude is installed
frech apt-get update, apt-get upgrade
Printing with this configuration is no problem
verified configuration of plug in firmware updater several time, it's as described in many documents on the web

the octoprint log shows:

2018-10-26 21:25:59,595 - octoprint.plugins.firmwareupdater - INFO - Firmware update started
2018-10-26 21:25:59,612 - octoprint.plugins.firmwareupdater - INFO - Disconnecting from printer

2018-10-26 21:26:02,676 - octoprint.server.preemptive_cache - INFO - ... done in 64.17s

but nothing happens. There is also no message on the printer display.
Any idea, what could be wrong.

Thank's Wolfgang

Re: OctoPrint - Firmware update stuck?

I have the same problem I guess. Mine hangs when trying to update firmware.

It’s one of the main reasons I got all the hardware and installed OctoPrint, to be able to update firmware...so disappointing : /

It seems like it used to work in the past based on forum posts, but I guess not anymore.

Re: OctoPrint - Firmware update stuck?

Have you tried disconnecting in OctoPrint first?

I was having a similar issue, found this thread - then attempted to do it manually and that seems to have worked

avrdude done. Thank you.

will have to wait for the next firmware to see if i can do it natively via the UI.
