[SOLVED] Can't Seem to Program Arduino Uno

Troubleshooting
1

Hey All,

Apologies if this question has been asked but I’ve searched the forums with no luck yet. I should preface that I am in no way a competent programmer, I have taken a few Kahn academy courses and consider myself technically savy for the average guy on the street, but that’s it.

I’m trying to build a BrewPi setup using a Raspberry Pi 2and a Sanismart Uno Arduino. I successfully installed Raspbian and ran the BrewPi install script, BrewPi opens up on the browser and the script is running. I installed this yesterday so I can only assume it’s the current version of BrewPi.

Essentially I can’t seem to get the Maintenance panel within BrewPi to program the Arduino. I did successfully execute the blink test through the Arduino IDE but so far that’s all I can get to work.

When I try to use the maintenance panel to program the Arduino, I consistently get this error message:

“Cannot receive version number from Arduino. Your Arduino is either not
programmed or running a very old version of BrewPi. Please upload a new
version of BrewPi to your Arduino”

I’ve seen other posts with this error but they all have additional content output by BrewPi that I don’t see on my screen.

I’m using the Arduino Uno Hex file from here, I’ve tried both versions A and C: https://github.com/BrewPi/firmware/releases/tag/0.2.10

I’ve even tried using some newer Hex files that I know are not correct for my Arduino to see if i could simply get it to flash onto it with a newer version, but no luck. I’ve attempted the troubleshooting tips as well but no luck (header 4.2 here: http://docs.brewpi.com/after-install/program-arduino.html)

Any suggestions?

Did you run:

sudo ~/brewpi-tools/updater.py --ask

And choose the legacy branch?

3

Nope but I will try that. Would this downgrade me to a legacy version of BrewPi?

4

Yes, the newest version won’t run on an Arduino. You can also try flashing the hex file with xloader: http://xloader.russemotto.com/

5

Thanks Elco! I did try using Xloader but ran into driver issues.

6

Xloader seems to have done the trick!

7

The following command worked for me with using an Arduino. Run this command and then try to program again.

sudo echo ‘E\n’ > /dev/ttyACM0

8

There is a button to reset the settings stored in EEPROM in the web interface now (bottom of advanced settings). There should be no need to run that manually now. I don’t think that was the issue though.

9

All set gents, thanks for the help! Got it up and running and successfully tested it, switches between heat and cool correctly. Thanks for everything you do Elco!

Hi Elco,

Think I’m having similar issues, I have the latest Arduino Uno (Arduino Uno ATmega328 MCU Board Rev 3).

I have:

  • reset the device using sudo echo ‘E\n’ > /dev/ttyACM0

  • I can successfully install the blink test from my mac using the usb cable

  • I can interagate the device using avrdude from the pi:

    avrdude: AVR device initialized and ready to accept instructions

    Reading | ################################################## | 100% 0.00s

    avrdude: Device signature = 0x1e950f
    avrdude: Expected signature for AT90USB82 is 1E 93 82

    avrdude: safemode: Fuses OK (E:00, H:00, L:00)

    avrdude done. Thank you.

I’m using a Rap. Pi. model B, and latest version of debian installed

I have checked out and loaded the legacy version of the software

I’m getting these errors:

I have not had much luck with XLoader it does not respond :frowning: on my Mac when I try to upload a hex file

I’m using brewpi-arduino-uno-revC-0_2_10.hex of the firmware and selecting uno in the web interface, the file gets uploaded to uploads correctly, but not applied.

Any help would be very gratefully appriciated, I’ve been hacking away at this for a few days now.

Thanks in advance !

OK, I’ve just installed grblflash https://dl.dropboxusercontent.com/u/54312401/grbl/grblflash on another linux box, though sure will work on the pi too and the firmware has now installed corectly.

Thanks! had same issue when i updated to a RPI 3 thanks for the GRBLFLASH link, works fine from RPI

13

I was having problems getting the script to recognise the Arduino clone.

I ran

sudo echo ‘E\n’ > /dev/ttyACM0

then flashed the .hex file on the ‘Funduino Uno’ using grbflash

All good now.

thanks guys!

14

You got the order of that wrong. The reset EEPROM command does nothing if the firmware is not installed yet.

Try the legacy_dev branch please. It should work again to just flash from the web interface.

15

Thanks Elco,
To be fair I was trying a number of things in no particular order. The good thing it is operational now.

Thanks again

Hi Elco (or anyone else),

I am new to programming and this is my first BrewPi Community post. I have successfully installed the BrewPi web interface on my RPi. When I am trying to program the Arduino using the brewpi-arduino-uno-revC-0_2_10.hex firmware, I am getting the same error message as everyone else.

“Cannot receive version number from Arduino. Your Arduino is either not
programmed or running a very old version of BrewPi. Please upload a new
version of BrewPi to your Arduino”

I made sure I was using the legacy branch. I tried resetting the EEPROM using the code posted, as some have suggested. I tried different programming settings in the controller settings. I was going to try the Xloader option, but I am using a Mac. Nothing that I have read seems to work.

Any help would be appreciated!

Is your legacy branch up to date? Then the updater should be able to program your Arduino.

The reset EEPROM code does nothing if the Arduino is not programmed, it is a BrewPi specific command. In fact, it should not be used anymore, there is a button in the web interface to reset to factory defaults.

18

Ok. So I went back (again) and updated my legacy branch. I even tried the legacy_dev as you suggested to someone else. Currently back on legacy. This is what I get:

Then, went to BrewPi interface and reset controller to factory defaults under advanced settings. Finally, went to Reprogram Controller. Uploaded hex code as stated in earlier reply, chose Arduino Uno, and both settings were changed to NO. Went to Program the Arduino and this is what I get:

Thanks for your help!

The problem is that it cannot find a compatible serial device.

I have updated the code to print a better error message.

Please run: python autoSerial.py and check its output. It will list the available serial ports and show what it thinks is compatible.

20

Here is what I got after entering the code:

python: can’t open file ‘autoSerial.py’: [Errno 2] No such file or directory

I’m guessing based on your description that my Arduino is not recognizing any serial ports.
