in at compile-time from makefile. also added and renamed built bootloader images for Micro and Leonardo
2012-03-14bugfix for Caterina not starting sketch if "verify upload" turned off in IDE.Zach Eveland
Previously, if avrdude skipped the upload step the read while write memory might never be reenabled. This would prevent the bootloader from ending and the sketch from starting - the bootloader just continued to run even after a successful upload. Now enable RWW when we receive the AVR109 "Exit bootloader" 'E' command. Had to disable lock bit changing support in the bootloader to free up flash for the change - will anyone miss it?
2012-03-14changed Caterina timeout after self-programming to 500 ms (from 250 ms)Zach Eveland
attempt to fix bug reported by Dave Mellis: "avrdude: ser_close(): can’t reset attributes for device: Invalid argument" is thrown after attempting an upload in the IDE (though the upload seems to be successful)
2012-03-08give Leonardo bootloader 250 ms to finish housekeeping before leaving ↵Zach Eveland
self-programming mode Earlier approach had bootloader end as soon as it was told to. On Linux this caused problems with avrdude because the microcontroller never had a chance to send an acknowledgement.
2012-03-08removed old version of Leonardo's caterina bootloader, replaced with ↵Zach Eveland
LUFA-based caterina
2012-03-01reduced Caterina timeout to 8 seconds from 16Zach Eveland
2012-02-14Leonardo now checks whether bootloader should be run after a WDT event.Zach Eveland
Before the sketch initiates an auto-reset for upload it pokes a magic word into a specific RAM address. On starting the bootloader checks this address. If it finds the magic word it knows the bootloader code should run. If not it jumps straight back to sketch. Test in a sketch by adding to setup(): wdt_enable(WDTO_2S); Sketch should upload, start, run for two seconds, WDT, and sketch should restart (not bootloader). Had to cut out unused descriptor code to make the bootloader still fit in 4k.
2012-02-14Leonardo bootloader jumps straight to sketch for a power-on reset.Zach Eveland
Disconnect programmer after burning bootloader to get the full effect. ICSP and JTAG programmers do a hardware reset after any reset condition, confusing the firmware a little.
2012-02-13changed Leonardo bootloader and sketch PID values again (now 0x0701 for ↵Zach Eveland
bootloader, 0x0801 for sketch)

string, and serial number
2012-02-07fixed bug in Caterina which caused some programming instructions to failZach Eveland
Timer 1 interrupts were trashing self-programming timing. Now disable Timer 1 compare match before doing Flash tasks and reenable afterward.
2012-02-06increased Leonardo bootloader timeout to 16 secondsZach Eveland
2012-02-03proper bootloader timeout and LED control in Leonardo bootloaderZach Eveland
2012-01-24Caterina now cleanly hands off operation to the sketchZach Eveland
had to remove TIMER1 operation from bootloader - was interfering with normal sketch operation

after upload finished.

2012-01-10renamed DiskLoader to Caterina (after Leonardo's mom)Zach Eveland
2012-01-10changed USB PID for Leonardo and Micro bootloadersZach Eveland
sketch and bootloader will use different PIDs to distinguish one from the other.

Phillip Torrone)
2012-01-10got rid of u8, u16, u32 typedefs in DiskloaderZach Eveland
done to bring types in line with others in Arduino core
2012-01-10made the bootloader's LED control macro names less offensiveZach Eveland
TX_LED_OFF() instead of TXLED0, etc.
2012-01-10added conditional compilation for HID, removed conditional compilation for ↵Zach Eveland
CDC (is always used). disabled HID by default. also always enumerates as composite now. the bootloader must always have a CDC interface. HID is optional and not even complete to reduce size.
2012-01-10fix bug in handling of long descriptors for bootloader USB (thank you, Todd ↵Zach Eveland
Krein, Limor Fried, and Phillip Torrone) descriptors longer than 255 bytes were being shortened, causing problems with enumeration under Windows
2011-12-31reset the Leonardo board when leaving the bootloader, before starting the sketchZach Eveland
Done so all IO and other registers are properly reinitialized when a new sketch is uploaded or when an existing sketch is started. Uses a watchdog timeout with a 15 ms period to accomplish the reset. Bootloader checks the reason for reset and only enumerates as bootloader and enters the programming loop if reset was NOT caused by WDT.
