This is a relatively significant edit that brings the Arduino copy of
optiboot up-to-date with the optiboot source repository as of Jun-2011
(the last changes made in the optiboot repository were in Oct-2010)
This adds support for several plaforms, fixes the "30k bug", and
refactors the source to have separate stk500.h, boot.h, and pin_defs.h
These are the arduino opticode issues fixed:
http://code.google.com/p/arduino/issues/detail?id=380
optiboot has problems upload sketches bigger than 30 KB
http://code.google.com/p/arduino/issues/detail?id=556
update optiboot to the point of the latest optiboot project sources.
These are issues that had been solved in the optiboot source aready:
http://code.google.com/p/arduino/issues/detail?id=364
optiboot leaves timer1 configured when starting app, breaks PWM on
pin 9 and 10. (fixed with a workaround in arduino core.)
aka http://code.google.com/p/optiboot/source/detail?r=c778fbe72df6ac13ef730c25283358c3c970f73e
Support for ATmega8 and mega88.
Fix fuse settings for mega168 _ISP targets
Additional new platforms (mega, sanguino)
http://code.google.com/p/optiboot/issues/detail?id=26
Set R1 to 0 (already in arduino code)
http://code.google.com/p/optiboot/issues/detail?id=36&can=1
Fails to build correctly for mega88
After this commit, the only differences between the Arduino optiboot.c
and the optiboot repository optiboot.c are cosmetic.

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.
|
||||
|
||||

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
