I'm trying to upload my exported HEX file by avrdude using this command /Users/user_acc/Downloads/Arduino.app/Contents/Java/hardware/tools/avr/bin/avrdude -C/Users/user_acc/Downloads/Arduino.app/Contents/Java/hardware/tools/avr/etc/avrdude.conf -v -patmega32u4 -cavr109 -P/dev/cu.usbmodem1421 -b57600 -D -Uflash:w:/Users/user_acc/Documents/Arduino/at_command_A6/at_command_A6.ino.with_bootloader.leonardo.hex:i

But instead of loading the file it's stuck on connecting to programmer.

Output: https://scr.hu/rYNzzm https://paste.ubuntu.com/p/74p37fGYPN/

The output from ArduinoIDE is exactly the same and it finds the programmer without the problem and loads the file.

Output: https://scr.hu/M72NaV

Can somebody help me? :)

  • please update the second picture so that it shows the command line (roll the screen down a bit) – jsotola Apr 1 '18 at 18:21
  • @jsotola I added the whole output from Arduino in the paste.ubuntu.com link – pawisoon Apr 1 '18 at 18:38
  • @jsotola Thats the output from Arduino. What command line do you want to see? – pawisoon Apr 1 '18 at 18:46
  • go to "preferences" in the Arduino IDE .... check "show verbose output during" upload .... do an upload ..... the actual avrdude command line gets diplayed .... post that command line – jsotola Apr 1 '18 at 19:16
  • @jsotola it was all the time in the output that I provided. Its in the question now as well. Dont mind the cu.usbmodem124. I changed the port during my attempts. – pawisoon Apr 1 '18 at 19:21

I found a post of somebody with a similar issue. His solution fixed my issue!
