Firmware 0.4.4 has been released (You MUST update!)

NottingHill · December 20, 2016, 6:36pm

I changed to ‘Beer constant’ and now the heating did start. I will do some testing after this beer is done.

Have you checked this setting? The Dead time when switching between actuators? I seem to remember that the default setting is 1800 which will set a minimum wait between cooling and heating to 30 minutes.

NottingHill · December 21, 2016, 7:47pm

Thanks, I am trying that

tried running the updater everything seems to go great but when I ran the updater again my photon still got v0.4.3
maybe has something to do with th blank screen I got since yesterday. The script won’t run also.
I want to try and reprogram the photon but can’t seem to find the hex file (http://dl.brewpi.com/brewpi-avr/stable) link from the install instructions is not working. What can I try? got the spark last week.

----Update
i did a clean install and seems like the touch screen works like it should;.in test mode i can manually controll the 4 outputs. screen is still white though. And when running updater: Current firmware version on controller: 0.4.3
and won’t upgrade to 0.4.4

Elco · January 5, 2017, 2:28am

You should update by running our update script. It fetches the latest version from GitHub.
sudo python ~/brewpi-tools/updater.py

Those files on dl.brewpi.com are very old. The latest releases are on github:
https://github.com/BrewPi/firmware/releases

If your display is blank, but you do hear 2 beeps at startup, there is something wrong with your display and I should ship you a replacement. PM me your address if that is the case. The displays can be a bit unreliable and I am switching to a new supplier in the next re-iteration of the hardware.

Update appeared to complete without error, however the Script Running button seems to refresh every so often as Script not Running, then back to Script Running.
Data is logging and graph is showing data however.

stderr.txt shows no errors:

I have the Tilt Hydrometer customizations configured.

in stdout.txt, I see one error message:

ERROR: TiltHydrometer (Black): Unable to initialise Gravity Calibration data (tiltHydrometer/GRAVITY.black) - list index out of range

That GRAVITY.black file has one calibration point from 1.011 -> 1.000 (“tare” with water)

#Gravity Calibration file for Tilt Hydrometer
#To be active, the file should be named GRAVITY.<colour> in the tiltHydrometer/ folder
#and have at least one calibration value inside.
#So to calibrate a black tilt hydrometer, the file would be called GRAVITY.black
#The following example two calibration points are used. 
#0.997 read from the tilt hydrometer will be calibrated to the actual value of 0.999
#1.056 read from the tilt hydrometer will be calibrated to the actual value of 1.060
#Other calibration points will be calculated.

#Original SG Value, Calibrated Value
#0.997, 0.999
#1.056, 1.060
1.011, 1.000

NottingHill · January 13, 2017, 5:33pm

@SBowler, the author of the Tilt modifications can probably confirm, but to me your GRAVITY file looks wrong. If I am not mistaken, GRAVITY needs two entries, the TEMPERATURE file only needs one.

For the second calibration point, mix some sugar or DME in water and confirm with a glass hydrometer. I would calibrate somewhere in the 1.050 - 1.060 range.

Stefan

frizzo · January 13, 2017, 5:41pm

@NottingHill @sbowler

Hi Stefan, That makes some sense intuitively, however, seems contrary to the file’s comment “and have at least one calibration value inside”, and the idea that even the brewometer smartphone app allows a single “tare” with water as a baseline adjustment. Was hoping/expecting this implementation to follow suit. If it doesn’t then a bug in the gravity file comments for sure.

I took your advise and add a second calibration point (arbitrary for now) and STILL got the same error. Updated GRAVITY.black file:

#Original SG Value, Calibrated Value
#0.997, 0.999
#1.056, 1.060
1.011, 1.000
1.056, 1.060

so that doesn’t seem to be the cause.

frizzo · January 13, 2017, 5:52pm

@sbowler @NottingHill
Even simply with the sample file copied as GRAVITY.black, I get the same error…
cp ~brewpi/tiltHydrometer/GRAVITY.colour ~brewpi/tiltHydrometer/GRAVITY.black

something buggy in the code???
do I have a line termination issue perhaps? (currently just linux-style LF)

NottingHill · January 13, 2017, 6:09pm

See the reply from @Richard_Crump in the Integration thread, the chnages do not like the blank line.

Elco · January 13, 2017, 7:00pm

For the web interface reporting script not running intermittently, in your apache.conf file, set KeepAliveTimeout to 99 instead of 5.

frizzo · January 13, 2017, 9:44pm

Thanks @Elco @nottinghill, @sbowler for your help. wonderful products, super-helpful community.

Appears the pi and scripts updated okay, but it fails to update the FW on the spark…gets to this point and exits when coming out of DFU mode. Suggestions? Snippet from update script follows:

Having some issues with the update of my firmware as well. Get to a similar point as spenceme, however I get a different issue. It will simply loop with this error - Syntax error: word unexpected (expecting “)”), so I ctrl-c to stop it. The BrewPi has a solid white screen, and is blinking yellow. If I unplug and replug (reboot), everything comes back up no issues, but firmware upgrade is not working.

Here’s what I’m getting. Any ideas?

I think this is a problem with a local dfu install.
Please try uninstalling dfu-util and let the updater download it:
sudo apt-get remove dfu-util

spenceme · January 16, 2017, 10:25pm

Fixed here. I think it was again due to an incompletely inserted USB cable. Thanks again

jaspass · January 17, 2017, 1:43am

Thanks for the advice Elco! Unfortunately I didn’t have luck there. After running the remove dfu-util command I got this:

I tried running the updater.py again, but got the same syntax error as before. It is about here I wish I were stronger with being able to troubleshoot this myself. Thanks for any support!

Elco · January 17, 2017, 12:43pm

If the updater does not work, can you try these alternative approaches:

cd /home/brewpi/utils

First try:

sudo python updateFirmware.py --dfu

If that does not work:

sudo python flashDfu.py --autodfu

jaspass · January 18, 2017, 2:36pm

I am having no luck, keep running into the same message. When I ran the updateFirmware.py --dfu I get the following:
