Hi,
out of the box i had some permission issues. So i created my own udev rule: sudo nano /etc/udev/rules.d/51-jtagice3.rules
# Atmel Corp. AVR JTAGICE3 (v3.x) Debugger and Programmer
SUBSYSTEM=="usb", TAG="JTAGICE3",ACTION=="add",ATTRS{idVendor}=="03eb",ATTRS{idProduct}=="2140",MODE="0660",GROUP="plugdev",OWNER="z004kw1n"
sudo chmod 644 /etc/udev/rules.d/51-jtagice3.rules
with that i can:
avrdude -c jtag3isp -p m328p
avrdude warning: USB device with VID: 0x03eb and PID: 0x2110 not found
avrdude: AVR device initialized and ready to accept instructions
avrdude: device signature = 0x1e950f (probably m328p)
avrdude done. Thank you.
but the arduino IDE still complains...
avrdude: WARNING: invalid value for unused bits in fuse "lock", should be set to 1 according to datasheet
This behaviour is deprecated and will result in an error in future version
You probably want to use 0xff instead of 0x3f (double check with your datasheet first).
avrdude: verification error, first mismatch at byte 0x0000
0xff != 0x0f
avrdude: verification error; content mismatch
Failed to burn bootloader: uploading error: exit status 1
After that i flashed the bootloader on there using avrdude:
avrdude -c jtag3isp -p m328p -U ATmegaBOOT_168_atmega328_pro_8MHz.hex
avrdude warning: USB device with VID: 0x03eb and PID: 0x2110 not found

avrdude: Note: flash memory has been specified, an erase cycle will be performed.
To disable this feature, specify the -D option.

after which the error message changes again:

avrdude: stk500v2_jtag3_recv(): error in jtagmkII_recv()

The bootloader i got from here and I am using the zip File IDE on Ubuntu 24.04LTS.
I can upload sketches to that Uno fine and i can also get the board info if that is of interest.
Anyone an idea?
