Odd behaviour when programming with UPDI
Hi MCUdude,
I'm having odd behavior with an ATMega4809 when trying to program it via UPDI. I'm able to burn a bootloader via UPDI and using an Arduino Nano (Nano+4.7K+10uF). In that conditions, I can program the ATMega4809 with FTDI.
The problem is when I try to program directly with UPDI, i.e., with the same setup used to burn the bootloader but uploading with no bootloader option and JTAG2UPDI as a programmer (I'm using Arduino IDE 1.8.13). Everything compiles and no error is shown, but the program is not being uploaded. I'm testing with a simple blink example. This is the log:

avrdude done. Thank you.
That's strange! What happens if you re-arrange the avrdude command, so that the last thing that happens is that the hex file is written?
Here's your Avrdude command, but slightly modified where the flashing happens at the end.

I found that the command works if I replace Blink.ino.with_bootloader.hex:i with Blink.ino.hex:i
When I compile the sketch with Arduino IDE, two .hex files are generated (and saved in arduino_build_755460 folder) : Blink.ino.with_bootloader.hex and Blink.ino.hex.
I think the problem is that for some reason when I upload the sketch, Arduino IDE tries to write Blink.ino.with_bootloader.hex:i, instead of Blink.ino.hex:i, although I have defined the option no bootloader.
The problem is when I try to program directly with UPDI, i.e., with the same setup used to burn the bootloader but uploading with no bootloader option and JTAG2UPDI as a programmer (I'm using Arduino IDE 1.8.13).
I am not so sure how this can happen. Maybe an IDE bug which may have been fixed. Ref:
