I've tried connecting Arduino Mega 2560 with Atmega16u2 chip and it also doesn't work OS X El Capitan 10.11.2 (15C50) (hackintosh if it changes anything).I also have one such arduino, but it works properly after installing signed drivers as described here.Īre there any solutions for atmega 16u2 chips? I've searched a lot, and it seems that people mostly had problems with arduinos on CH340 chips. Manufacturer: Arduino (Location ID: 0x1a140000 / 6īut it doesn't show up in arduino program ports. When connected, it is visible in system information under USB section: If you are using arduino as isp you would use -cstk500v1 -P/dev/ttyACM0 -b19200 avrdude -p atmega16u2 -P usb -c usbasp -U flash:w:Arduino-COMBINED-dfu-usbserial-atmega16u2-Uno-Rev3.I have Chinese copy of arduino which uses ATmega16u2 (at least that's what is written on the chip itself). Notice I changed the -p atmega16u2, the -c usbasp and the Arduino-COMBINED-dfu-usbserial-atmega16u2-Uno-Rev3.hex Something like this: /home/kprims/.arduino15/packages/arduino/tools/avrdude/6.3.0-arduino14/bin/avrdude -C/home/kprims/.arduino15/packages/arduino/tools/avrdude/6.3.0-arduino14/etc/nf -v -p atmega16u2 -cstk500v1 -P/dev/ttyACM0 -b19200 -U flash:w:Arduino-COMBINED-dfu-usbserial-atmega16u2-Uno-Rev3.hex -U lfuse:w:0xFF:m -U hfuse:w:0xD9:m -U efuse:w:0xF4:m -U lock:w:0x0F:m I used the avrdude command for the Uno v3 and changed it to this.You may have to use the avrdude with the arduino IDE. ![]() ![]() I then cd into: cd /home/kprims/ken/Downloads/arduino-1.8.5/hardware/arduino/avr/firmwares/atmegaxxu2 I just updated an atmega16u2 on an Uno Clone using Linux Mint and IDE1.8.5. ![]()
