Mkr 1400 upload very long and No device found on ttyACM0

Development Tools IDE 1.x
1

Hi,
I use a mkr1400 as a shield + Mkr GPS and until now, all was working well particularly when I was uploading sketches.
Since today, after install tinyGPSPlus (I don't know if it is linked but I mention that), the upload of a simple sketch on the mkr1400 shield spend a long time (may be 2 minutes) and finishes by printing "no device found on ttyACM0". I uninstalled tinyGPSplus library but the problem stills be so I supposed that it was not the problem.
I tried to add all rights to /dev/ttyACM0 :
chmod a+rwx /dev/ttyACM0

I checked the baud rate of /dev/ttyACM0 after the error :

stty -F /dev/ttyACM0 
speed 115200 baud; line = 0;
min = 0; time = 0;
-brkint -icrnl -imaxbel
-opost
-isig -icanon -iexten -echo -echoe -echok -echoctl -echoke

Thank you for your help
I add the detailed output of the compilation + upload:

Hi @stache06. Is /dev/ttyACM0 labeled like "/dev/ttyACM0 (Arduino MKR GSM 1400)" in the Tools > Port menu of the Arduino IDE?

3

Hi @in0
Yes it is.

The way uploads work is:

  1. The Arduino IDE (or the upload tool used by the Arduino IDE) sends a signal for the microcontroller to reset.
  2. The microcontroller resets.
  3. The bootloader runs and waits (normally only for a short time) for an upload to start.
  4. The upload tool sends the program to the microcontroller, where the bootloader writes it to flash memory.

On the boards with native USB (such as your MKR GSM 1400), the way the IDE signals the microcontroller to reset is by opening a serial connection at 1200 baud. There is some special code running on the microcontroller in the background of your sketch that does the reset when it detects that 1200 baud connection.

In some cases, your sketch code might cause that reset code to be missing or not working correctly, which will mean the bootloader never runs and the upload fails with the error you're seeing.

The fix is to manually reset the board.

Try this:

  1. Press and release the reset button on your board quickly twice.
    You should now see the LED on the board pulsing, which means the bootloader is running.
    The double reset causes the bootloader to run until the board is reset normally, powered off, or an upload is done.
  2. Select the port of your board from the Tools > Port menu.
    The port may be different when the bootloader is running so don't assume you already have the correct port selected.
  3. Start an upload in the Arduino IDE.

The upload should now finish successfully.

After this, you should be able to go back to doing normal uploads without needing to use the reset button technique. If you still need to do the reset trick to do uploads after this, the problem may be caused by your code. You can verify this by uploading a simple sketch like File > Examples > 01.Basics > BareMinimum.

5

the SAMD boards do this if the MCU is already in bootloader at the time of the upload. the "1200 baud touch" reset then doesn't work so the port detection can't detect port change and waits until the timeout

6

Thanks @in0 , for your detailed explanation. I will try this and keep you updated.

7

Except in that case the upload would have succeeded.

8

Thank you @in0 and @Juraj :
I pressed the reset button twice but no led were pulsing
I checked the port name in the IDE which was the same
I uploaded my code : it spent a short time
Thanks again :slight_smile:
PS : I am trying to solve another completely different problem : as I said in the descroption the shield is connected to a mkr gps one, and the GPS is never available. It has worked at the very begining I used it but now it is always saying that the GPS is not available : do you see something to do ?
