Danny Nguyen 746058306b Make sure NOBITS is set on reset_key
Patch from https://github.com/qmk/qmk_firmware/issues/3657#issuecomment-415147411

Long story short, in avr-gcc pre-8.2, reset_key was assigned to a memory area that was in a normal range, but when 8.2 came out, that memory got moved to an out of range area, causing errors like 0x800293 out of range. Apparently, this was fixed up in avr-gcc, but we haven't seen a release with the fix yet (we expected it in 8.3, but that didn't happen for some reason).

What this commit does is move the reset_key back to the original memory location it was in before.

TMK Keyboard Firmware Core Library

This is a keyboard firmware library with some useful features for Atmel AVR and Cortex-M.

Source code is available here: https://github.com/tmk/tmk_keyboard/tree/master/tmk_core

Updates

2016/02/10

flabbergast's Chibios protocol was merged from https://github.com/flabbergast/tmk_keyboard/tree/chibios. See protocol/chibios/README.md. Chibios protocol supports Cortex-M such as STM32 and Kinetis.

Debugging

Use PJRC's hid_listen to see debug messages. You can use the tool for debug even if firmware use LUFA stack.

You can use xprintf() to display debug info on hid_listen, see common/xprintf.h.
