2. Oct. 2006 - Version 0.81 12. Apr. 2008 - Version 0.83
* Bernhard Roth reported a mistake in the UART-configuration * Added definitions for ATmega644P and ATmega324P
for double-speed. Thanks for the report. * Tested with ATmega324P, gcc 4.2.2, avr-libc 1.4.6
Change in main.c: * Added testapp to verify "exit bootloader" with
UART_STATUS = UART_DOUBLE; -> UART_STATUS = (1<<UART_DOUBLE); watchdog (n.b.: watchdog-disable called early in testapp)
27. Jan. 2007 - Version 0.82
* Added definitions for ATmega644.
* Using avr-lib's eeprom-functions (old "direct-access"-code
has not been compatible with ATmega644).
* Watchdog-disable at startup (configurable): avoids problems with
repeated login to bootloader. Not needed if the bootloader is
never re-entered again between an "exit programming" and
a system-reset/power-toogle.
* Additional watchdog disable-function for ATmega644.
* Made watchdog-enable time at exit-programming a configuration-value
(define).
* Bootloader read-protection: if enabled the bootloader fakes
an empty boot-section (configurable by define)
Since more of the avr-libc functions's are used this version
should be more portable for other AVRs but the size of the
binary increases a little bit.
Make sure to disable the watchdog early in the user-application
esp. when using a "modern" AVR (i.e. ATmega48/88/168/644/324P/644P).
3. Dec. 2006 - Version 0.81
* Added definitions for ATmega162.
