| - | Everything about the Arduino bootloader one can find here: | + | If one uses an Atmega328 chip in his Arduino or Paperduino project one needs to burn a bootloader. That program allows later for an easy upload of programs. For the Paper-Arduino-Clones we have to burn the Arduino UNO bootloader on our ATmega chip. Depending on the burning device there are a lot of different technics to do so. |

| + | === Burning an Atmega328 (without P) === | ||
| + | |||
| + | The Atmega328 chip has a different signature than the Atmega328p (p stands for picoPower). When one wants to burn this chip with the IDE the avrdude.conf file has to be changed.\\ | ||
| + | Open the file: | ||
| + | /usr/share/arduino/hardware/tools/avrdude.conf | ||
| + | or (depends on the Arduino version): | ||
| + | /usr/share/arduino/hardware/tools/avr/etc/avrdude.conf | ||
| + | search for the Atmega328p signature:\\ | ||
| + | 0x1e 0x95 0x0F | ||
| + | and replace it with the Atmega328 signature:\\ | ||
| + | 0x1e 0x95 0x14 | ||
| + | Now it should be possible to burn the Atmega328 with the Arduino IDE. Don't forget to change it back for the P version of the Atmega chip. | ||

| + | === Fuse Bits === | ||
| + | In the board.txt file for the Arduino UNO the fuse bits are set like that: | ||
| + | uno.bootloader.low_fuses=0xFF | ||
| + | uno.bootloader.high_fuses=0xDE | ||
| + | uno.bootloader.extended_fuses=0xFD | ||
| + | uno.bootloader.unlock_bits=0x3F | ||
| + | uno.bootloader.lock_bits=0x0F | ||
| + | The extended fuse bits settings for the brown-out detection level (BOD) are: | ||
| + | 0xFF (BOD disabled) | ||
| + | 0xFC (BOD = 4.3V) | ||
| + | 0xFD (BOD = 2.7V) | ||
| + | 0xFE (BOD = 1.8V) | ||
| + | That is the level where the Arduino resets when underpowered.\\ | ||
| + | |||
| + | A good manual for calculating the fuse bits one findes here [[https://www.instructables.com/id/How-to-change-fuse-bits-of-AVR-Atmega328p-8bit-mic/]]. | ||

| + | === Problem Solving === | ||
| + | To erase all fuse bits one can use the attribute: -e\\ | ||

| - | and replace it with the Atmega328 signature:\\ | + | |
| - | 0x1e 0x95 0x14 | + | |
| - | Save and close (contr O and contr X)\\ | + | |
| - | Now you can burn the Atmega328 with the Arduino IDE (Arduino Uno). | + | |
