From 4f44d2893a506ee3924785c91a5f8983c013150c Mon Sep 17 00:00:00 2001 From: WestfW Date: Fri, 10 Jun 2011 16:17:13 -0700 Subject: 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.

When avrdude runs and talks to an arduino running ArduinoISP, it needs the optiboot (entered due to auto-reset) to abort and start the ArduinoISP "application" when it sees communications at the wrong serial speed. Unfortunately, optiboot treats all unrecognized command characters as "no-ops" and responds/loops for more commands, leading to a nice loop that never gets to the sketch. This patch causes characters received with Framing errors (the most likely error for speed mis-matches) to NOT reset the watchdog timer (normally done in getch()), which will cause the application to start if it continues for "a while." (tested. Works! Running ArduinoISP at speeds as high as 57600 still causes the bootloader to start the sketch (although it fails later on for other reasons.)) --- bootloaders/optiboot/pin_defs.h | 1 + 1 file changed, 1 insertion(+) (limited to 'bootloaders/optiboot/pin_defs.h') diff --git a/bootloaders/optiboot/pin_defs.h b/bootloaders/optiboot/pin_defs.h index 313e453..27d7772 100644 --- a/bootloaders/optiboot/pin_defs.h +++ b/bootloaders/optiboot/pin_defs.h @@ -21,6 +21,7 @@ #define UDR0 UDR #define UDRE0 UDRE #define RXC0 RXC + #define FE0 FE #define TIFR1 TIFR #define WDTCSR WDTCR #endif -- cgit v1.2.3-18-g5258
