BrewPi 0.4.0/0.4.1 upgrade issue

Troubleshooting
1

I attempted this upgrade without success using this process:

login to brew using SSH…

And then ran the following commands:

cd ~/brewpi-tools
sudo python updater.py

The Spark now has a blank screen and a flashing centre blue light.

I haven’t changed anything in the hardware…the USB lead is still connected…I’ve rebooted both RPi and Spark several times…I’ve reset the Spark to factory and redone the upgrade but i can’t get past the “unable to connect to controller”

Here is the script:

[pi@raspberrypi / $ sudo ~/brewpi-tools/updater.py

In case this is material…

$ sudo python /home/brewpi/autoSerial.py
All ports: ((’/dev/ttyACM0’, ‘ttyACM0’, ‘USB VID:PID=2b04:c006 SNR=00000000050C’),)
Compatible ports: ((’/dev/ttyACM0’, ‘Particle Photon’),)
Selected port: (’/dev/ttyACM0’, ‘Particle Photon’)

I set the Spark into DFU mode and attempted a direct flash…still cannot get the serial port opened…Spark screen is still blank and the light on the bottom is out…

I’ve got 5 gallons of Pale in the middle of fermenting…I guess the moral of the story is if it ain’t broke…which it wasn’t …don’t try to upgrade it!

Any ideas?

Now the Spark is flashing red…nothing I do seems to change that…In novice terms how do I recover from this?

5

Just to be sure, reset to factory default firmware from Particle by holding the setup button during reset for 10 seconds. It will start blinking fast. When done, your photon is flashing blue.

Enter DFU mode by holding the setup button for 5 seconds during reset.
When in DFU mode, run flashDfu.py

Keep an eye on your controller to go through the touch screen calibration when it asks for it.

When your controller is communicating with the script again, reset to factory defaults in the web interface under advanced settings.

6

Thanks Elco…I’ll try that and report back…

7

I’ve tried this 5 times and the photon flashes several different colours then when I release the button it flashes red…I’ve tried slightly les than 10 seconds and slightly more but it only ever flashes red…

8

That is strange. A factory reset should always be possible.

If you can still put it in DFU mode, can you try just running flashDFU.py again?

9

It looks like I can do that…i.e. it flashes amber after 5 secs or so and this is what I get…

$ sudo python /home/brewpi/utils/flashDfu.py

OK…I had to go to the root directory and execute the command before it works…the same as before…cannot open the serial port…

Flashing the first binary was successful, but there were errors during the second and third file.

I think this is because the USB communication is unreliable. Most likely due to a bad USB cable, or if you pulled on the cable a bit too much, an unreliable connector on the photon. Third option is a too small power supply on the Pi.

Please try with a different USB cable.

I have 2 cables…This is the 2nd. Looks oike I’m getting the exact same error…

I have a 2 amp PS for both the RPi and the Spark.

Could not open serial port after programming

Ok, at least that looks like it flashed correctly.

That does confirm my suspicion of the Photon’s USB port. I think if you reset the BrewPi Spark and then use the factory defaults button in the web interface, it will be updated correctly. However, the USB port will remain unreliable.

16

It does look like that port is a tad unreliable…

How do I reset the BrewPi Spark?
Presumably the web interface is the RPi?

Thanks for the help, Elco…/David

17

I’ve rebooted the Spark…and there are no beeps…and the screen is blank…and the LED is a solid red…

18

It sounds like it is a good idea to replace that Photon anyway. At least for the USB port.

Could you send it back for investigation? I can ship you a new one.

19

Sure…happy to do that tomorrow…what address shall I send it to? Shall I send the whole unit?

Just the photon is enough, so you can use a envelope that fits through the mail slot.
