Unable to flash arduino pro micro from Terminal

Question 1

I am trying to upload an hex file to my arduino pro micro using Avrdude . The thing is that I cannot upload any code using the Avrdude terminal commands , but when I use arduino IDE to upload any code it perfectly uploads the code to Arduino.

The command I am using on the terminal:

avrdude -C C:\Users\santi\AppData\Local\Arduino15\packages\arduino\tools\avrdude6円.3.0-arduino17/etc/avrdude.conf -v -V -patmega32u4 -cavr109 -PCOM15 -b57600 -D -U flash:w:C:\Users\santi\Documents\keyboard\corne\crkbd_rev1_layout_split_3x6_3_mine.hex:i

I already have avrdude on the environment variables on my windows 10 machine.

I keep waiting but it does not upload the code.

I added a push button for RST and GND pins to enter bootloader mode, and I am pressing the reset button. I even tried resetting twice quickly, but I get the same result.

I tried using the Arduino and the code gets uploaded.

I uploaded the following code:

int RXLED = 17; 
void setup(){
 pinMode(RXLED, OUTPUT); 
}
void loop() {
 digitalWrite(RXLED, LOW);
 delay(1500); 
 digitalWrite(RXLED, HIGH); 
 delay(1500); 
}

The command ran in the IDE is:

"C:\Users\santi\AppData\Local\Arduino15\packages\arduino\tools\avrdude6円.3.0-arduino17/bin/avrdude" "-CC:\Users\santi\AppData\Local\Arduino15\packages\arduino\tools\avrdude6円.3.0-arduino17/etc/avrdude.conf" -v -V -patmega32u4 -cavr109 -PCOM16 -b57600 -D "-Uflash:w:C:\Users\santi\AppData\Local\Temp\arduino-sketch-F0563C64AD4C1F392D3E71AA32E4F874/blink_nano.ino.hex:i"

I tried using the same Avrdude command in the terminal.

I don ́t know why it uses a different port. I tried changing the port in that command but I get the same result as before

I could just use the arduino IDE to flash my device but the problem is that I only have the hex file. I am trying to flash my device with a hex file from QMK Configurator. I am trying to build a custom keyboard.

Question 2

When you tried the same command as the IDE, did you close the IDE? There is a possibility that it has the port open, which will block other programs from accessing it.

Question 3

You have to reset the Arduino using a very special procedure in order for it to accept being programmed. This involves opening the port at 1200 bps, toggling some control lines, and closing the port again. You may try using this ard-reset-arduino Python script with the option --caterina.

By the way, this script belongs a project called "Arduino-Makefile". You may want to take a look if you want to program your Arduino from the command line. Alternatively, you can use arduino-cli.

Question 4

"I am trying to flash my device with a hex file from QMK Configurator." The arduino-cli does the 1200baud touch as part of the upload process, but it might not apply or may need clarification on how to apply. I'm not sure how you'd make use of it unless it has the ability to be supplied arbitrary hex files to upload, or has a stand-alone command for issuing a 1200 baud touch, or unless you can sneak your hex file over top of one the compile command had created. "I even tried resetting twice quickly" This should have given them 8 seconds of bootloader time, though the tool would help.
