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)

2012-02-07changed Caterina descriptors - Arduino LLC VID, new PID, manufacturer ↵Zach Eveland
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
2012-01-21move interrupt vector table to application section before jumping to it ↵Zach Eveland
after upload finished.
2012-01-21Leonardo bootloader checks reason for reset and jumps immediately to sketch ↵Zach Eveland
if reset was caused by WDT
2012-01-19stripped all LUFA LED control. from LUFA-based CaterinaZach Eveland

2012-01-19initial checkin of LUFA 111009 CDC bootloaderZach Eveland
2012-01-10made Leonardo and Micro bootloader PIDs same as sketch PIDsZach Eveland
2012-01-10restored composite and non-composite device descriptors (removed in ↵Zach Eveland
4b05c3fc7529477fb7031d42103c15b50a6b58be) Windows wants to see both types of device descriptors.
2012-01-10reenabled HID to force Leonardo bootloader to enumerate as a composite deviceZach Eveland
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.
2012-01-10fixed warning when comparing pgm_read_word(0) to -1 (thanks, Limor Fried and ↵Zach Eveland
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.
2011-12-26bootloader merged with blink sketchZach Eveland
full set of descriptors in sketch fixes driver installation issue on Win7.
2011-11-25Correcting Arduino Mini w/ ATmega328 bootloader file and fuses (untested).David A. Mellis
2011-11-16Leonardo bootloader now sends iSerial string during enumeration. Seems to ↵Zach Eveland
satisfy Windows' composite device requirements.
2011-11-09restored original non-interrupt-driven DiskLoaderZach Eveland
Interrupt-driven version was a dead-end - too many bugs with that approach.
2011-10-31changed Leonardo PID to 0x0032 for Diskloader testing. updated .inf to match.Zach Eveland
2011-10-31check to see if a sketch has been loaded before jumping out of bootloaderZach Eveland
2011-10-27Revert "Merge branch 'master' of github.com:arduino/Arduino into ↵Zach Eveland
