Photon upgrade problem

Troubleshooting
6

That’s the main LED which is unlit…The one that’s blue, which is the only lit LED is the small blue LED underneath the right reset button.

I’ve tried resetting using your first instruction, several times.

  1. I get white flash, yellow flashing, green flashing, white flashing…then I release the button and get white flash, red SOS, red flash, red SOS, white flash, red flash, red SOS, red flash, red SOS.

  2. I try again and it goes straight into red, white, red SOS, red, red SOS - repeat.

  3. try again and I get sequence No. 1…then sometimes it freezes on green…

Mostly it just flashes red, red SOS, white, red, red SOS repeatedly which seems to indicate a hardware failure.

I can get it into DFU mode…so I removed all previous downloads…and ran
sudo python /home/brewpi/utils/flashDfu.py and get this…

pretty much same as before.

Now my Spark has gone back to it’s original state with just the tiny right hand led glowing blue.

…and still the screen is blank and I get no sounds on rebooting.

7

That tiny blue LED is D7…nothing else is lit.

8

That does sound like an issue with the photon. Can you identify which SOS code you get?

9

Where SOS is dot dot dot dash dash dash dot dot dot, I get:

white flash, red SOS, red flash, red SOS, white flash, red flash, red SOS, red flash, red SOS.

I don’t know how better to describe it. I don’t have a list of SOS codes from which to select the meaning…sorry.

I’ll try and upload a video of the LEDs.

10

After a night of being switched off I now cant get the LED to flash red so I’m interpreting this as a good thing…I’ve followed your instructions

  • Reset the photon to factory firmware: hold the setup button and reset. It will start flashing yellow (DFU mode). Keep holding the setup button until it starts flashing white. Wait until the white flashing is over. You are now back to factory firmware.
  • Remove all previous downloads from the pi to be sure it’s not a corrupt download causing the trouble:
    From pi@raspberrypi - pls confirm this is correct
    sudo rm -R /home/brewpi/utils/downloads
  • Run flashDfu again
    From pi@raspberrypi/home/brewpi - pls confirm this is correct
    sudo python /home/brewpi/utils/flashDfu.py

I get this: (still flashing yellow, can’t find serial port, blank screen and no beeps when restarting)

Reset

http://vid1032.photobucket.com/albums/a405/fatbaldingoldgit/Photon%20reset.mp4

12

I’m now stuck in blinking yellow / DFU mode.
Seems to me like the USB port is suspect because it can’t write the new firmware to the Photon.
Could it be a driver problem or is it a hardware issue?

http://vid1032.photobucket.com/albums/a405/fatbaldingoldgit/DFU%20mode.mp4

13

I think I may have control now…have the main LED flashing blue…after following instructions here while connecting the Photon directly to my Mac:

more later…fingers crossed

14

OK…so put this into DFU mode again and ran

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

Got this: (still no serial port access, screen is blank, no beeps on startup and the LED is flashing red
red, red SOS, red, red SOS etc…

back to square one…

So…summary so far.
Accessing the Spark and Photon via my Mac USB I can load firmware, connect to it via my iPhone, upgrade the firmware via my Mac.
I can do everything on the Photon that Particle say I should be able to do.
Accessing it via my RPi I can download the latest Brewpi firmware but it fails at the point where the USB port is accessed.

I’m stumped…thoughts anyone?

16

After you have flashed it via DFU on the pi, is it running BrewPi? Do you see stuff on the screen? Does it beep twice at startup?

The DFU uploads seem to succeed, so it looks like there is nothing wrong with the USB communication.

17

No…nothing on the screen and no beeps.

What is the significance of the serial port failure?

What do you think is the issue?..do you need more information?

18

I don’t think the serial port failure is the main issue here. If the controller doesn’t run properly, the serial port will not work either. Your new photon will be delivered tomorrow probably. Will be good to know whether that fixes it.

Then I think it would be good if I can get my hands on the broken photon to investigate.

19

Fedex tried to deliver this morning but we were out…being delivered tomorrow…should be able to hook it up later tomorrow to test. I think I’ve now got the Photon into base Particle delivered mode…No problem with doing that, curiously…I’ve even connected via Wifi and upgraded the firmware.

For now I’ve hooked up my duplicate RPI…currently upgrading to latest RPI code and firmware…then I’ll try and refresh the photon with the latest Brewpi code and firmware…see if I get stuck the same way again.

This issue seems very similar to the last time we replaced the Photon and I sent that one back for investigation. What was wrong with that one?..Maybe something to learn from that?

Assuming I have no luck using a different RPi and reflashing I’ll send this Photon back for investigation.

20

*** SUCCESS ***

OK…so with my duplicate RPi and my Photon in base Particle mode
I ran these:

sudo apt-get update
sudo apt-get upgrade
sudo rpi-update
sudo reboot
sudo ~/brewpi-tools/updater.py
cd ~
wget http://dfu-util.sourceforge.net/releases/dfu-util-0.7-binaries/linux-armel/dfu-util

Now resetting EEPROM to defaults

Resetting EEPROM to default settings
INFO MESSAGE 15: EEPROM initialized

My Spark screen is now running in hardware test mode and it rebooted with 2 beeps.

Now to hook it all up to the sensors and see where my Galaxy singe hop has got to.

So…what does all this mean?..

21

So this is still with the old photon?
It seems like the only thing that you changed is an apt-get upgrade and a firmware upgrade.
Maybe the latter made the USB/serial connection work reliably?

22

No…I ran all those steps before…but the Photon got it’s knickers in a twist somehow…I managed to get it back to Particle default by connecting direct to my MAC although I don’t think how I did it was material.

I still think it’s a tad flaky…can’t get it out of hardware test mode even though all three sensors are connected and working…and the web interface seems to be communicating with it…I did have an issue with configuring the devices…some changes stayed sticky, others didn’t take at all…the response from the Spark was inconsistent.

Right now I’m in temperature monitoring mode and the beer is at 15 degrees…the lower end of what my yeast likes…but it’s fermenting away happily still…

I’ll plug the new Photon in when it arrives and see if anything changes.

Do I need to upgrade anything on the Photon or is it ready to go?

23

To get it out of test mode, you just need to apply beer or fridge constant mode.
If you want me to take a look, add me on Skype (elcojacobs).

The photon I shipped needs to be flashed with FlashDFU

24

Ah…OK…I’ll apply a constant mode…thanks…didn’t know that…

I’ll add you to Skype…once I’ve installed it…5 mins…OK?

27

Looks to be working fine so far…wonder what the problem was?..
