!!!!Burning Sketches to the Mini

To burn sketches to the mini you must first make a cable to interface between your programmer and the mini board. Gian Pablo Vilamil has written a very good tutorial on [[http://www.arduino.cc/en/Hacking/MiniBootloader | Bootloading the Mini]]. To burn sketches, follow the instructions on bootloading the mini.

Once you have made the proper cable, instead of bootloading, you can use the instructions on this page to burn sketches directly to the mini.

You must specify which Arduino board you are using, but you do not have to specify a serial port (on Mac at least).

This preferences file is found in this folder:
* /Users/<USERNAME>/Library/Arduino/preferences.txt (Mac)
* c:\Documents and Settings\<USERNAME>\Application Data\Arduino\preferences.txt (Windows)
* ~/.arduino/preferences.txt (Linux)

Note that when you upgrade Arduino, this folder may not be deleted. If you are having trouble, delete this folder. Upon launching Arduino a new file and preferences.txt will be created.

!!!!AVRISP mkII

If you have an AVRISP mkII, you'll need to burn your sketches outside the Arduino environment. You can use a program like avrdude, avrstudio, or winavr. To generate the .hex file that you'll be burning, press the upload button in the Arduino environment. The .hex file will be saved in the '''applet''' sub-directory of the sketch's directory (which you can find by selecting '''Show Sketch Folder''' from the '''Sketch''' menu of the Arduino environment).

!!Burning sketches to the Arduino board with an external programmer

If you have an external programmer (e.g. an AVR-ISP, STK500, or [[parallel programmer]]), you can burn sketches to the Arduino board without using the bootloader. This allows you to use the full program space (flash) of the chip on the Arduino board. So with an ATmega8, you'll get 8 KB instead of 7. It also avoid the bootloader delay when you power or reset your board.

!!!!Editing the Arduino preferences file

To use an external programmer you need to make three changes to the Arduino [[preferences | preferences.txt]]. Make sure to edit this file when the Arduino IDE is not running.

First, change: \\
@@serial.download_rate=19200@@ \\
to: \\
@@serial.download_rate=115200@@

Second, change @@upload.erase@@ and @@upload.verify@@ from @@false@@ to @@true@@.

!!!!Burning the sketch

After you've made these changes, you can burn sketches to the board with the normal upload button or menu item in the Arduino environment. The board needs to be powered, but you don't have to press the reset button before uploading.

!!!!Going back to normal USB/serial upload

To go back to uploading sketches over the USB or serial port without an external programmer, you'll need to change back those lines in preferences.txt. You'll also need to burn the [[bootloader]] back onto the chip on the Arduino board.

If you have an AVRISP mkII, you'll need to burn your sketches outside the Arduino environment. You can use a program like avrdude, avrstudio, or winavr.
