/** \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;

that may prevent the Application and Boot Loader section from any

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

/* Heavily optimised bootloader that is faster and */

/* */
/* Enhancements: */
/* Fits in 512 bytes, saving 1.5K of code space */
/* Background page erasing speeds up programming */
/* Higher baud rate speeds up programming */
/* Written almost entirely in C */
/* Customisable timeout with accurate timeconstant */
/* Optional virtual UART. No hardware UART required. */
/* Optional virtual boot partition for devices without. */
/* */
/* What you lose: */
/* Implements a skeleton STK500 protocol which is */
/* missing several features including EEPROM */
/* programming and non-page-aligned writes */
/* High baud rate breaks compatibility with standard */
/* Arduino flash settings */
/* */
/* Fully supported: */

/* */
/* Does not support: */
/* USB based devices (eg. Teensy) */
/* */
/* Assumptions: */
/* The code makes several assumptions that reduce the */

/* */
/* Jan 2012: */
/* 4.5 WestfW: fix NRWW value for m1284. */
/* 4.4 WestfW: use attribute OS_main instead of naked for */
/* main(). This allows optimizations that we */
/* count on, which are prohibited in naked */
/* functions due to PR42240. (keeps us less */
/* than 512 bytes when compiler is gcc4.5 */
/* (code from 4.3.2 remains the same.) */
/* 4.4 WestfW and Maniacbug: Add m1284 support. This */
/* does not change the 328 binary, so the */
/* version number didn't change either. (?) */
/* June 2011: */
/* 4.4 WestfW: remove automatic soft_uart detect (didn't */
/* know what it was doing or why.) Added a */
/* check of the calculated BRG value instead. */
/* Version stays 4.4; existing binaries are */
/* not changed. */
/* 4.4 WestfW: add initialization of address to keep */
/* the compiler happy. Change SC'ed targets. */
/* Return the SW version via READ PARAM */
/* 4.3 WestfW: catch framing errors in getch(), so that */
/* AVRISP works without HW kludges. */
/* http://code.google.com/p/arduino/issues/detail?id=368n*/
/* 4.2 WestfW: reduce code size, fix timeouts, change */
/* verifySpace to use WDT instead of appstart */
/* 4.1 WestfW: put version number in binary. */
