Uploading From Linux with avrdude

[jwatson]

Hello,

I'm looking to upgrade my firmware form 1.5 to 1.6. Recent restrictions at work prevent me from using my (work) Windows laptop to do this as I have done in the past so I was wondering if it's possible to perform the upgrade from my home Linux machine using the avrdude command from the terminal? I'm comfortable using the terminal and can determine some of the parameters but not the -U parameter. If it's possible to use avrdude from the command line, please could you provide an example of the complete command?

Many thanks

James

Hi James,

I haven't done it on LInux, but here's the Avrdude command that the Arduino IDE uses on my Windows machine, which may be of some help:

avrdude -CC:\Program Files (x86)\Arduino\hardware\tools\avr/etc/avrdude.conf -v -V -patmega32u4 -cavr109 -PCOM5 -b57600 -D -Uflash:w:C:\Users\Andrew\AppData\Local\Temp\arduino_build_329919/WARBL_1.6.ino.hex:i

You would replace the locations of the avrdude.conf file (probably wherever Avrdude is installed) and the hex file. The other key thing is that Avrdude is looking for an open serial port, but WARBL only opens a serial port when you double-click the programming button (that's because it can't be a class-compliant MIDI device if it keeps extra serial ports open all the time). So, you need to double-click the button just before you run the Avrdude command. Also, you need to know the name of the serial port that WARBL is going to open, so you can put that into the command ahead of time. To do that, you double-click the button first and use whatever tools Linus has to see the name of the new serial port that opens. On Windows you go into the Device Manager and watch the list of USB devices. I suspect Linux has something similar. Then you would take that port name and enter it into the command, double-click the button again, run the command, and cross-your fingers .

Hopefully that helps, but I'm happy to do more research if that doesn't work for you.

Hello Andrew,

Many thanks for your quick response and help. I've upgraded my Warbl from v1.5 to v1.6 using a laptop running Fedora 30 using the following procedure.

1. Determine the programming port by comparing the output of the command 'ls /dev/' before and after setting the Warbl to programming mode by double-clicking the Warbl's program button.

2. Disable modem services (This may not be required but some online sources indicate that Modem Services can interfere with programming.)

Code: Select all

sudo systemctl stop ModemManager.service

3. Enter the command but don't hit enter just yet (Note the -P and -U parameters will need to be tailored to your own configuration.

Code: Select all

sudo avrdude -v -V -p m32u4 -c avr109 -P /dev/ttyACM1 -b 57600 -D -U flash:w:/home/jwatson/Downloads/WARBL_1.6.ino.hex 

4. Disconnect and reconnect the Warbl and double-click the programming button. Hit 'Enter' in the terminal to start the programming (see screen capture below).
5. Restart modem services.

Code: Select all

sudo systemctl start ModemManager.service

The following shows the output when running the update command;

Code: Select all

[jwatson@localhost ~]$ sudo avrdude -v -V -p m32u4 -c avr109 -P /dev/ttyACM1 -b 57600 -D -U flash:w:/home/jwatson/Downloads/WARBL_1.6.ino.hex

Excellent! Thanks for reporting back with the procedure, and I’m glad it worked!

[jwatson]

I've just upgraded to v2.0 using the procedure above but had a problem connecting to the Warbl until I disabled autosuspend in tlp. Edit the file /etc/tlp.conf and change USB_AUTOSUSPEND=1 -> USB_AUTOSUSPEND=0. After a reboot I was able to connect to the Warbl using the above procedure.
