I need to be able to let an Rpi program an Arduino nano. I must controll the Rpi via an SSH connection. This Rpi will be placed on a difficult to reach spot with an arduino nano plugged in. This nano is likely to need updates.
I am following this url from arduino-cli. but I am dead in the water.
When i run the board list command I see that it can find on on the usb port but it does not recognize it:
pi@raspberrypi:~/Downloads/MyFirstSketch $ arduino-cli board list Port Type Board Name FQBN Core
/dev/ttyAMA0 Serial Port Unknown
/dev/ttyUSB0 Serial Port (USB) Unknown
I also tried:
pi@raspberrypi:~/.arduino15 $ arduino-cli board listall
Board Name FQBN
But it does not neem to know any board at all.
I have had serial communication with the arduino nano in a processing sketch, so that one is working for sure.
I did every step in the tutorial, I ran the core update command:

Unlike the Arduino IDE, Arduino CLI does not come with the Arduino AVR Boards core pre-installed (because not everyone uses AVR boards). You need to run this command:
arduino-cli core install arduino:avr

This will still occur even after you have installed Arduino AVR Boards. The reason is the Nano uses a general purpose USB to TTL serial adapter chip (FTDI FT232RL on the official and clone Nanos, CH340 on the derivative Nanos). The way Arduino CLI identifies boards is via the VID/PID of the chip providing a USB interface. The USB to serial adapter chip on the Nano uses the manufacturer's stock VID/PID, so there is no way for the Arduino CLI to know what device is using that VID/PID (for example, I have multiple non-Arduino consumer electronic devices connected to my computer that use the FT232). So with the Nano you just need to figure out which port it has (you can do this by checking which new port appears after you plug the Nano in to your computer), and use that in your upload command.
All the other official Arduino boards have custom VID/PID, which allows them to be identified by the arduino-cli board list command.
The Arduino forum is definitely the right place for this type of question. I did move your topic to the "Arduino CLI" forum board, since this is an Arduino CLI-specific question.
Thank you for your help. I now can compile the sketch succesfully but the uploading does not yet work. I am also thinking to not compile on the rpi but on my W10 host PC instead so I can just transfer the .hex file and call an upload script on the pi. I can SSH in without password so I think that should be more effective. ~~ ~~pi@raspberrypi:~/Documents/software $ arduino-cli compile -b arduino:avr:nano beep Sketch uses 932 bytes (3%) of program storage space. Maximum is 30720 bytes. Global variables use 9 bytes (0%) of dynamic memory, leaving 2039 bytes for local variables.

This was completely new to me. May it be that arduino-cli also expects a different bootloader? Is this configurable? boardname is listed as: Arduino Nano arduino:avr:nano I cannot find references to bootloaders with the --help flag. EDIT: I found 2 hex files, but as arguement I pass on the folder and not a single hex. pi@raspberrypi:~/Documents/software $ ls beep beep.arduino.avr.nano.elf beep.arduino.avr.nano.hex beep.arduino.avr.nano.with_bootloader.hex beep.ino I tried: pi@raspberrypi:~/Documents/software $ arduino-cli upload -b arduino:avr:nano -p /dev/ttyUSB0 -t -i beep/beep.arduino.avr.nano.with_bootloader.hex avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x00 and I did the same with the other hex as well but same results Why is the upload process failing and how can I fix this?
I had a good idea. I googled it...
I had to add something to the board string:
arduino:avr:nano:cpu=atmega328old
This solves the problem and I can now succesfully load hex file to the program.
Now I just have to configure my W10 PC to produce this same hex so I can compile locally. Safes me alot of file tranfers
I hope arduino-cli works with the src subdirectory as welll?
