Only C99 types are used now. + o Size is now 1878 bytes, 6314 bytes user space. No changes to functionality. + +== 1.10rc2 - 2013-11-25 == + +firmware: + o It seems that the USB specification does not define a maximum delay from device power up until + the host issues a bus reset. Therefore too short delays AUTO_EXIT_NO_USB_MS can lead to the + bootloader exiting before enumeration on some systems. Disabled AUTO_EXIT_NO_USB_MS in default configuration. + +== 1.10rc1 - 2013-11-25 == + +firmware: +Version jump to 1.10 due to major changes in firmware by @cpldcpu. + o Reduced code size to below 2kb (1974 with standard configuration) by implementing oscillator + calibration in assembler and various local code tweaking. See Github commit history for full details. + This version has 6208 bytes programmable code space. + o Micronucleus will now simulate an USB-disconnect when exiting the bootloader. This prevents various + issues with having a non-responsive USB device, including crashing the host tool. It is now possible + to enter the bootloader again by resetting the device using the watchdog timer or the reset input without + physically disconnecting from USB. + o Cleaned up bootloaderconfig.h + o Introduced a second time-out (AUTO_EXIT_NO_USB_MS) if no USB reset from the host is detected. This can be used + to quit the bootloader early if the device is not connected to USB. The bootloader will enter the user + program after ~0.8s with the default settings instead of 6s when USB is connected. + o Introduced optional code to flash a LED. See LED_PRESENT in bootloaderconfig.h for details. + Careful: Right now enabling the LED-code requires setting the bootloader base address to 0x1800 due + to increased code size. + + == 1.06-jumper-v2 - 2013-5-20 == firmware: |
