Cannot upload Hex Code to my Arduino [Solved]

MylesMac · March 20, 2015, 3:32pm

Hello,

I am trying to set up a new system that I made using a Raspberry Pi B+ and an Arduino UNO (may be a knockoff but I was able to run Blink so I think its working ok). I’m very new to the Raspberry Pi and BrewPi so I appreciate everyone’s patience.

I have followed the BrewPi software installation instructions, I have done the sudo apt-get update, sudo apt-get upgrade, rpi-update and I think I have all the python packages I need. I have verified that the Arduino shows up on my Pi using lsusb and checked the serial communication ports between the Raspberry Pi and the Arduino usingls /dev/ttyA*. The ports listed were ttyACM0 and ttyAMA0 so I changed the alternate communication port in the config.cfg file to ttyAMA0.

My problem is uploading the hex code. When I open the BrewPi web interface the message says “Script Running” but I am unable to upload the hex code to my arduino. I have posted the error messages I am getting below. I really appreciate any help that can be offered.

Please choose Uno as board type, not 328 based.

MylesMac · March 20, 2015, 5:06pm

Thanks Elco.

Are you referring to the drop-down box on the “Reprogram Arduino” page? If so, I did choose “Uno” and selected No to the “Restore old settings” and “Restore installed decives” options. I have also tried uncommenting the board type in the config.cfg file and typing in “Uno” and “UNO”. No luck so far.

wbarber69 · March 20, 2015, 9:02pm

Try a different usb cable

Elco · March 20, 2015, 10:39pm

Hmm, yes, I did not look at the command well. The processor is m328p, the protocol is arduino, which is correct. I think wbarber69’s suggestion is good. Crappy USB cables can cause a lot of issues.

MylesMac · March 20, 2015, 11:09pm

I tried a different cable first and the “View Logs” printout for it is the first one listed below. After that I switched the “Board Type” drop down box from “Uno” to “ATmega328 based” and tried is again with the Uno rev C hex code and the second set of “View Logs” printouts are below for that. It appears the USB cable didn’t change anything but something actually worked better when I selected the 328 board. The script is currently running and the BrewPi status screen in the top left of the page is showing “Mode Off” and giving me a idle time counter. Does this mean its working? Thanks for all your help so far:

Yes, that seems to have worked.
I guess your UNO knockoff is not really an UNO knockoff but an earlier version.
The Uno has an atmega16u2 as serial converter chip, while the older versions had and FTDI chip. They also used different serial protocols. Your ‘UNO’ might have an older version of the bootloader.

I am able to program the Arduino with it hooked up to my rpi (which it is now) through Arduino IDE. I was able to clear the EEPROM and upload Blink. Not really sure where to go from here…

wbarber69 · March 21, 2015, 4:41am

having a similar issue here. I have 4 knock-off pro minis. I got all 4 to program correctly once. I changed a bit of the avr code to reflect my project. now when I try to upload I am successful on 3 out of the 4. the fourth one however is giving me the out of sync error now for some reason. I do have brewpi up and running on it but I can no longer use the programmer to upload to this board. I guess its a bad bootloader or something I have run everything I can think of. tried erasing the eeprom - not in sync. tried uploading blink - not in sync. tried different revisions of brewpi - not in sync. I even re-soldered all the connections, no luck. dont really know where to go from here.

wbarber69 · March 21, 2015, 6:52am

Hmmm… I figured it out on my end. Apparently dtr is no longer a functional contact on this particular board. I was finally able to run a sketch in ide by hitting reset at the right time. My user to serial interface has multiple options for reset, so I tied one of them directly to one of the minis reset pins and was finally able to upload the hex.

MylesMac · March 21, 2015, 7:13am

OK so when I set my board type as ATmega328 I am able to see all my devices in the detected devices area. The temp sensors are reading the correct temperature and they are displaying it in the top left corner of the BrewPi main screen. The problem I am having now is that I cannot get my devices to install. I am setting them up as instructed, clicking apply and then refreshing the device list but it keeps saying “no devices installed” yet it will still display the temperatures as read by the sensors. Should I be trying a different hex code (currently using Uno Rev C) or something else?

Thanks everyone for your help so far.

Elco · March 21, 2015, 9:02am

If you your settings do not stick, reset to default settings with: echo -ne 'E\n' > /dev/ttyACM0

I suspect this block of code is refactored incorrectly:

https://github.com/BrewPi/brewpi-script/blob/master/programArduino.py#L228

It should not re-open the serial port when attempting to close it. I don’t have time to test this myself this weekend, but I think line 232 should be removed.

MylesMac · March 22, 2015, 11:29pm

Thanks so much Elco. This seems to have worked for me. Appreciate all the advice!

Kobie · March 30, 2015, 7:25pm

Hi guys,

Is it possible there was a bug introduced in the latest version? My BrewPi (with Arduino Uno RevC) has been working fine for the past few months, but last night I tried updating everything to the latest version and get the same error as MylesMac.

The Pi defintely seems to see the arduino - if I click on ‘Refresh Device List’ I see the TX and RX lights flash on the Arduino.

Here’s my log (sorry for the dump - is there a way to add attachments to posts?)

This was indeed a bug, and this pull request should fix it:

Kobie · April 1, 2015, 7:05am

Thanks Elco. I actually got it working last night before I saw your post. I selected Leonardo from the menu instead of Uno, and although I’d already tried that several times, this time it worked for some reason.

For others who come across this post, I notice this posting that recommended flashing a simple/blank program to the arduino before flashing BrewPi. I didn’t do that but it may work for others:

Borisfa · April 6, 2015, 1:45am

Elco, when it will be implemented? When may I could update/upgrade Brewpi to fix it?

Thanks,

Fabiano

Hi

First time poster here…

I’ve added the changes to the best of my ability by manual editing the files, but I stil see some wierd behaviour. Now the flash process it self seems ok, but I still get the warning about unable to receive version number after the the script restarts :

Apr 12 2015 09:27:25 Warning: 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.

Any idea on what is causing this ?

Replying to myself here…

A reboot of the raspberry pi and the uno resolved this as it is working now…

Realised i’d posted in the wrong place before as had put it under firmware but this is more appropriate place and i’ll add what I have done to try and help others.

bear in mind i use a mac so things may differ on windows and linux.
ordered knock off chinese arduino’s because they were less than $3 trying to upload the hex caused a problem it just couldn’t find the Arduino, i swapped USB cables but nothing (it said it could not communicate to /dev/ttyACM0 or ACM1 or something similar)

to make sure my arduino wasn’t actually broken i downloaded Arduino software onto my mac and noticed that it didn’t appear under serial.

digging around i found out that some chinese knock offs don’t use the same USB/serial chip so i followed these instructions

i was then able to upload blink to the arduino and then once that had worked i uploaded a new sketch to the arduino (literally just clicking new and then upload not changing anything)

the next step was to work out what the tty serial was on the arduino

Ssh into the pi and with the arduino unplugged type

ls /dev/tty*

plug in the Arduino and type it again and see what has been added, in my case /dev/ttyUSB0

i next needed to edit the config.cfg file Brewpi manual hex upload instructions , i used cyberduck to do this, but i assume you can just

sudo nano /home/brewpi/settings/config.cfg

add in these two lines at the end
port = /dev/ttyUSB0
altport = /dev/ttyUSB1

and save out.

Hoping that had fixed my problem i went into brewpi web ui and tried to upload the Uno Rev C Hex file

to my frustration it spat out

Warning: Cannot receive version number from controller. Your controller is either not programmed or running a very old version of BrewPi. Please upload a new version of BrewPi to your controller.

Some more reading around on the forums and someone mentioned (in this thread) that using the following:

Hex File: brewpi-uno-revC.hex
board type: Leonardo
Restore old settings after programming: No
Restore installed devices after programming: No

worked for them.

so i tried this… low and behold i now have a chinese knock off Arduino running brewpi, everything seems to work, i’d love to know why it works but settle for the fact it just does.

hope this little write up helps others in the same boat.
