Note that you'll need to read both.

Keymap
Degug Console
hid_listen can't recognize device
When debug console of your device is not ready you will see like this:
Waiting for device:.........
once the device is pluged in then hid_listen finds it you will get this message:
Waiting for new device:.........................
Listening:
Check if you can't get this 'Listening:' message:
- build with
CONSOLE_ENABLE=yesin Makefile.
Can't get message on console
Check:
- hid_listen finds your device. See above.
- Enable debug with pressing Magic+d. See Magic Commands.
- set
debug_enable=yesusually inmatrix_init()in matrix.c. - try using 'print' function instead of debug print. See common/print.h.
- disconnect other devices with console function. See Issue #97.
Linux or UNIX like system requires Super User privilege
Just use 'sudo' to execute hid_listen with privilege.
$ sudo hid_listen
Or add an udev rule for TMK devices with placing a file in rules directory. The directory may vary on each system.
File: /etc/udev/rules.d/52-tmk-keyboard.rules(in case of Ubuntu)

Miscellaneous
NKRO Doesn't work
First you have to compile frimware with this build option NKRO_ENABLE in Makefile.
Try Magic N command(LShift+RShift+N by default) when NKRO still doesn't work. You can use this command to toggle between NKRO and 6KRO mode temporarily. In some situations NKRO doesn't work you need to switch to 6KRO mode, in particular when you are in BIOS.
If your firmeare built with BOOTMAGIC_ENABLE you need to turn its switch on by BootMagic N command(Space+N by default). This setting is stored in EEPROM and keeped over power cycles.

TrackPoint needs reset circuit(PS/2 mouse support)
Without reset circuit you will have inconsistent reuslt due to improper initialize of the hardware. See circuit schematic of TPM754.

Can't read comlumn of matrix beyond 16
Use 1UL<<16 intead of 1<<16 in read_cols() in matrix.h when your columns goes beyond 16.
In C 1 means one of int type which is 16bit in case of AVR so you can't shift left more than 15. You will get unexpected zero when you say 1<<16. You have to use unsigned long type with 1UL.
Pull-up Resistor
In some case converters needed to have pull-up resistors to work correctly. Place the resistor between VCC and signal line in parallel.
For example:
Keyboard Conveter
,------.
5V------+------|VCC |
| | |
R | |
| | |
Signal--+------|PD0 |
| |
GND------------|GND |
`------'
R: 1K Ohm resistor

Arduino Micro's pin naming is confusing
Note that Arduino Micro PCB marking is different from real AVR port name. D0 of Arduino Micro is not PD0, PD0 is D3. Check schematic yourself. http://arduino.cc/en/uploads/Main/arduino-micro-schematic.pdf
Bootloader jump doesn't work
Properly configure bootloader size in Makefile. With wrong section size bootloader won't probably start with Magic command and Boot Magic.
# Size of Bootloaders in bytes:
# Atmel DFU loader(ATmega32U4) 4096
# Atmel DFU loader(AT90USB128) 8192
# LUFA bootloader(ATmega32U4) 4096
# Arduino Caterina(ATmega32U4) 4096
# USBaspLoader(ATmega***) 2048
# Teensy halfKay(ATmega32U4) 512
# Teensy++ halfKay(AT90USB128) 1024
OPT_DEFS += -DBOOTLOADER_SIZE=4096
AVR Boot section size are defined by setting BOOTSZ fuse in fact. Consult with your MCU datasheet. Note that Word(2 bytes) size and address are used in datasheet while TMK uses Byte.
AVR Boot section is located at end of Flash memory like the followings.
byte Atmel/LUFA(ATMega32u4) byte Atmel(AT90SUB1286)
0x0000 +---------------+ 0x00000 +---------------+

And see this discussion for further reference. https://github.com/tmk/tmk_keyboard/issues/179
Special Extra key doesn't work(System, Audio control keys)
You need to define EXTRAKEY_ENABLE in makefile to use them in TMK.
EXTRAKEY_ENABLE = yes # Audio control and System control

Wakeup from sleep doesn't work
In Windows check Allow this device to wake the computer setting in Power Management property tab of Device Manager. Also check BIOS setting.
Pressing any key during sleep should wake host.
Using Arduino?
Note that Arduino pin naming is different from actual chip. For example, Arduino pin D0 is not PD0. Check circuit with its schematics yourself.
- http://arduino.cc/en/uploads/Main/arduino-leonardo-schematic_3b.pdf
- http://arduino.cc/en/uploads/Main/arduino-micro-schematic.pdf
Arduino leonardo and micro have ATMega32U4 and can be used for TMK, though Arduino bootloader may be a problem.
Using PF4-7 pins of USB AVR?
You need to set JTD bit of MCUCR yourself to use PF4-7 as GPIO. Those pins are configured to serve JTAG function by default. MCUs like ATMegaU or AT90USB* are affeteced with this.
If you are using Teensy this isn't needed. Teensy is shipped with JTAGEN fuse bit unprogrammed to disable the function.
See this code.
// JTAG disable for PORT F. write JTD bit twice within four cycles.
MCUCR |= (1<<JTD);
MCUCR |= (1<<JTD);
https://github.com/tmk/tmk_keyboard/blob/master/keyboard/hbkb/matrix.c#L67
And read 26.5.1 MCU Control Register – MCUCR of ATMega32U4 datasheet.
Adding LED indicators of Lock keys
You need your own LED indicators for CapsLock, ScrollLock and NumLock? See this post.
http://deskthority.net/workshop-f7/tmk-keyboard-firmware-collection-t4478-120.html#p191560
Program Arduino Micro/Leonardo
Push reset button and then run command like this within 8 seconds.
avrdude -patmega32u4 -cavr109 -b57600 -Uflash:w:adb_usb.hex -P/dev/ttyACM0
Device name will vary depending on your system.
