I tried flash bootloader into Arduino Pro Mini 328P 8MHz/3.3V clone, but got error.

First I did test:

~$ avrdude -c usbasp -p m328p
avrdude: AVR device initialized and ready to accept instructions
Reading | ################################################## | 100% 0.00s
avrdude: Device signature = 0x1e950f (probably m328p)
avrdude: safemode: Fuses OK (E:FD, H:D9, L:E2)
avrdude done. Thank you.

~$ avrdude -c usbasp -p m328p -v -U flash:w:optiboot_atmega328_pro_8MHz.hex

Would you like this fuse to be changed back? [y/n]

How to solve this?

First, I put the voltage jumper on USBASP programmer to 5V, to increase voltage. Then I set correct default fuse bits values for this board:

Arduino Pro or Pro Mini (3.3V, 8 MHz) w/ ATmega328
Low Fuse: 0xFF
High Fuse: 0xDA
Extended Fuse: 0x05
avrdude -c usbasp -p m328p -v -u -U lock:w:0x3f:m -U efuse:w:0xFD:m
avrdude -c usbasp -p m328p -v -u -U lock:w:0x3f:m -U hfuse:w:0xDA:m
avrdude -c usbasp -p m328p -v -u -U lock:w:0x3f:m -U lfuse:w:0xFF:m

Note, that I used option -u when modifying the fuse bits, this switch tell avrdude we really mean modify it. It disables the default behaviour of reading out the fuses three times before programming, then verifying at the end of programming that the fuses have not changed. I put 0xFD value for Extended Fuse Byte in place of 0x05, due to a bug in avrdude. (0xFD and 0x05 are the same value)

After that I flashed correct bootloader:

avrdude -c usbasp -p m328p -v -U flash:w:optiboot_atmega328_pro_8MHz.hex -U lock:w:0x0f:m

Now it fully fixed and works.

It is locked/blown. Looks like you tried to flash it previously as an Arduino Nano or Uno. Now the lock bits are set. Even in highVoltage programming mode you cannot discover it. Buy a new one.

  • discover? recover? Commented Nov 10, 2017 at 10:12
  • @Harald - no, I managed to fix it, easily enough. I will edit my question to add the solution. Commented Nov 11, 2017 at 23:05
