Command line upload port option does not support symlinks #6776

Open VictorLamoine opened 6 years ago

VictorLamoine commented 6 years ago

Arduino is plugged in on the RPi:

$ ls -l /dev/serial/by-id/usb-Arduino*
lrwxrwxrwx 1 root root 13 sept. 30 23:51 /dev/serial/by-id/usb-Arduino_LLC_Arduino_Micro-if00 -> ../../ttyACM1

Compiling/upload with port = /dev/ttyACM1 works:

arduino sketch.ino --port /dev/ttyACM1

But with port = /dev/serial/by-id/usb-Arduino_LLC_Arduino_Micro-if00 it fails:

An error occurred while uploading the sketch

Seems to me that the problem is the port being a symbolic link.

Alternative

arduino sketch.ino --port $(readlink -f /dev/serial/by-id/usb-Arduino_LLC_Arduino_Micro-if00)

Or is the problem that the symlink's name is not a known serial port name? What happens if you name the symlink /dev/ttyACM3 or something like that?

Also, it's a bit problematic that no meaningful error message is shown, that needs some looking at by itself too.

Hi @VictorLamoine, I believe that the problem is originated by avrdude ; launching the command with --verbose should give more meaningful results that we can use to debug the issue. Thanks!

Here is another run using the /serial/by-id/ in verbose mode:

$ arduino sketch.ino --port /dev/serial/by-id/usb-Arduino_LLC_Arduino_Micro-if00 --verbose

The problem is not the fact that it's a symbolic link, I have tried @matthijskooijman suggestion:

$ sudo ln -s /dev/ttyACM1 /dev/ttyACM9
$ ls -l /dev/ttyACM9 
lrwxrwxrwx 1 root root 12 Oct  2 20:01 /dev/ttyACM9 -> /dev/ttyACM1

Maybe avrdude makes some assumptions on a COM port name?

Not avrdude, but the Arduino IDE. The lines:

PORTS {/dev/ttyACM0, /dev/ttyACM1, /dev/ttyAMA0, } / {/dev/ttyACM0, /dev/ttyACM1, /dev/ttyAMA0, } => {}

Are generated by the Arduino IDE, which waits for the comport to become available before starting avrdude. The reason is that you're using an Arduino micro, which needs some special twiddling to make it reset into the bootloader. Because USB is builtin on the main chip, this also resets the USB connection, making the comport disappear and re-appear. The IDE waits for this before starting avrdude.

However, AFAIU this does not just check the specified com port, but instead monitors the list of available comports (as generated by the JSSC serial library, based on some regexes I suspect) and sees if any new ones appear (because after the reset, the micro might get a different port assigned than before, e.g. when the port is in use).

However, looking at the "broken" output, the line "Forcing reset using 1200bps open/close on port /dev/ttyACM9" is missing, which makes me suspect that it waits with the reset until the specified port is present in the JSSC port list. However, at least on Linux and OSX, it would probably be better to just check if the specified file exists (and if it's a link, if its target exists) instead of checking the JSSC port list. Alternatively, the IDE could resolve any symlinks and then continue processing with the actual port name.

This goes beyond my understanding of the Arduino programs :)

facchinm commented 6 years ago

@matthijskooijman the touch port routine just waits for any port to reappear and uses it as upload port. I believe that the code that fails is in fact the touch. I need to test on sysfs symlinks to understand if any action on the port might fail.
