This directory contains the Optiboot small bootloader for AVR
microcontrollers, somewhat modified specifically for the Arduino
environment.
Optiboot is more fully described here: http://code.google.com/p/optiboot/
and is the work of Peter Knight (aka Cathedrow), building on work of Jason P
Kyle, Spiff, and Ladyada. Arduino-specific modification are by Bill
Westfield (aka WestfW)
Arduino-specific issues are tracked as part of the Arduino project
at http://code.google.com/p/arduino
------------------------------------------------------------
Building optiboot for Arduino.
Production builds of optiboot for Arduino are done on a Mac in "unix mode"
using CrossPack-AVR-20100115. CrossPack tracks WINAVR (for windows), which
is just a package of avr-gcc and related utilities, so similar builds should
work on Windows or Linux systems.
One of the Arduino-specific changes is modifications to the makefile to
allow building optiboot using only the tools installed as part of the
Arduino environment, or the Arduino source development tree. All three
build procedures should yield identical binaries (.hex files) (although
this may change if compiler versions drift apart between CrossPack and
the Arduino IDE.)
Building Optiboot in the Arduino IDE Install.
Work in the .../hardware/arduino/bootloaders/optiboot/ and use the
"omake <targets>" command, which just generates a command that uses
the arduino-included "make" utility with a command like:
make OS=windows ENV=arduino <targets>
or make OS=macosx ENV=arduino <targets>
On windows, this assumes you're using the windows command shell. If
you're using a cygwin or mingw shell, or have one of those in your
path, the build will probably break due to slash vs backslash issues.
On a Mac, if you have the developer tools installed, you can use the
Apple-supplied version of make.
The makefile uses relative paths ("../../../tools/" and such) to find
the programs it needs, so you need to work in the existing optiboot
directory (or something created at the same "level") for it to work.
Building Optiboot in the Arduino Source Development Install.
In this case, there is no special shell script, and you're assumed to
have "make" installed somewhere in your path.
Build the Arduino source ("ant build") to unpack the tools into the
expected directory.
Work in Arduino/hardware/arduino/bootloaders/optiboot and use
make OS=windows ENV=arduinodev <targets>
or make OS=macosx ENV=arduinodev <targets>
Programming Chips Using the _isp Targets
The CPU targets have corresponding ISP targets that will actuall
program the bootloader into a chip. "atmega328_isp" for the atmega328,
for example. These will set the fuses and lock bits as appropriate as
well as uploading the bootloader code.
The makefiles default to using a USB programmer, but you can use
a serial programmer like ArduinoISP by changing the appropriate
variables when you invoke make:
make ISPTOOL=stk500v1 ISPPORT=/dev/tty.usbserial-A20e1eAN \
ISPSPEED=-b19200 atmega328_isp
The "atmega8_isp" target does not currently work, because the mega8
doesn't have the "extended" fuse that the generic ISP target wants to
pass on to avrdude. You'll need to run avrdude manually.
Standard Targets
I've reduced the pre-built and source-version-controlled targets
(.hex and .lst files included in the git repository) to just the
three basic 16MHz targets: atmega8, atmega16, atmega328.

/* Modified to use out for SPM access
** Peter Knight, Optiboot project http://optiboot.googlecode.com
**
** Todo: Tidy up
**
** "_short" routines execute 1 cycle faster and use 1 less word of flash
** by using "out" instruction instead of "sts".
**
** Additional elpm variants that trust the value of RAMPZ

/** \defgroup avr_boot <avr/boot.h>: Bootloader Support Utilities
\code
#include <avr/io.h>
#include <avr/boot.h>
\endcode
The macros in this module provide a C language interface to the
bootloader support functionality of certain AVR processors. These
macros are designed to work with all sizes of flash memory.
Global interrupts are not automatically disabled for these macros. It
is left up to the programmer to do this. See the code example below.
Also see the processor datasheet for caveats on having global interrupts
enabled during writing of the Flash.
\note Not all AVR processors provide bootloader support. See your
processor datasheet to see if it provides bootloader support.
\todo From email with Marek: On smaller devices (all except ATmega64/128),
__SPM_REG is in the I/O space, accessible with the shorter "in" and "out"
instructions - since the boot loader has a limited size, this could be an
important optimization.
\par API Usage Example
The following code shows typical usage of the boot API.
\code
#include <inttypes.h>
#include <avr/interrupt.h>
#include <avr/pgmspace.h>
void boot_program_page (uint32_t page, uint8_t *buf)
{
uint16_t i;
uint8_t sreg;
// Disable interrupts.
sreg = SREG;
cli();
eeprom_busy_wait ();
boot_page_erase (page);
boot_spm_busy_wait (); // Wait until the memory is erased.
for (i=0; i<SPM_PAGESIZE; i+=2)
{
// Set up little-endian word.
uint16_t w = *buf++;
w += (*buf++) << 8;
boot_page_fill (page + i, w);
}
boot_page_write (page); // Store buffer in flash page.
boot_spm_busy_wait(); // Wait until the memory is written.
// Reenable RWW-section again. We need this if we want to jump back
// to the application after bootloading.
boot_rww_enable ();
// Re-enable interrupts (if they were ever enabled).
SREG = sreg;

Bits by SPM To set the Boot Loader Lock bits, write the desired data to

that may prevent the Application and Boot Loader section from any
software update by the MCU.

will be programmed if an SPM instruction is executed within four cycles

recommended to load the Z-pointer with $0001 (same as used for reading the
