Burn arduino bootloader using ubuntu 16

Question

I get the following error when I try to burn the arduino bootloader on an atmega328 mcu:

avrdude: verification error, first mismatch at byte 0x0000
 0xfd != 0x05

I am using an Arduino as ISP programmer. My computer runs Ubuntu 16.

This did not happen when I was using Ubuntu 14. I also tested it on another machine with Ubuntu 14 and this error does not appear. Seems to be something with Ubuntu 16. I installed Arduino IDE using the out of the box repo.

The avrdude command launched by the IDE is:

/usr/share/arduino/hardware/tools/avrdude -C/usr/share/arduino/hardware/tools/avrdude.conf -v -v -v -v -patmega328p -cstk500v1 -P/dev/ttyUSB0 -b19200 -e -Ulock:w:0x3F:m -Uefuse:w:0x05:m -Uhfuse:w:0xde:m -Ulfuse:w:0xff:m 

Am I safe replacing the -Uefuse:w:0x05:m with -Uefuse:w:0xfd:m ?? If answer is yes how can I get the IDE to do this correctly?

Uploading a sketch works pretty well.

• Noury: This is not a real answer. I have the same problem on Os X, but I can upload sketch via "upload using programmer", but this way I have no bootloader. Problem arises only when trying to install boot loader. I didn't have this problem some years ago on Linux Debian. I your problem is solved, please let us know.
• Chris Stratton: There is no functional differences between an efuse setting of 0x05 and 0xfd, as only the three lowest bits actually exist. Your actual problem is elsewhere.

Answer 1

I had same problem and I think I have solved it.

In boards.txt file, I had:

I have replaced the line containing:

diecimila.menu.cpu.atmega328.bootloader.extended_fuses=0x05

with:

diecimila.menu.cpu.atmega328.bootloader.extended_fuses=0xFD

Everything is ok now.

I can install boot loader on an ATMEGA328P (with an usbasp programmer), and I can install sketchs after that (via usb serial).

I don't know if it's the best way to solve the problem, but it works. Hope this will help you, if not already solved.

• Chris Stratton: As there are only 3 bits in the extended fuses of an ATmega328p, 0x05 and 0xFD are actually the same value as far as the bits that exist. Different ways of handling the non-existent bits account for on the only difference, which is irrelevant.
