+# Frequently Asked Build Questions
-In short,
+This page covers questions about building QMK. If you haven't yet done so, you should read the [Build Environment Setup](getting_started_build_tools.md) and [Make Instructions](getting_started_make_guide.md) guides.
- $ make [-f Makefile.<variant>] [KEYMAP=...] clean
- $ make [-f Makefile.<variant>] [KEYMAP=...]
- $ make [-f Makefile.<variant>] [KEYMAP=...] dfu
+## Can't Program on Linux
+You will need proper permissions to operate a device. For Linux users, see the instructions regarding `udev` rules, below. If you have issues with `udev`, a work-around is to use the `sudo` command. If you are not familiar with this command, check its manual with `man sudo` or [see this webpage](https://linux.die.net/man/8/sudo).
+An example of using `sudo`, when your controller is ATMega32u4:
-## Can't program on Linux and Mac
-You will need proper permission to operate a device. For Linux users see udev rules below.
-Easy way is to use `sudo` command, if you are not familiar with this command check its manual with `man sudo` or this page on line.
-
-https://developer.apple.com/library/mac/documentation/Darwin/Reference/ManPages/man8/sudo.8.html
-
-In short when your controller is ATMega32u4,
-
$ sudo dfu-programmer atmega32u4 erase --force
$ sudo dfu-programmer atmega32u4 flash your.hex
$ sudo dfu-programmer atmega32u4 reset
-or just
-
- $ sudo make dfu
-
-But to run `make` with root privilege is not good idea. Use former method as possible.
+or just:
-## Do 'make clean' before 'make'
-You'll need `make clean` after you edit **config.h** or change options like `KEYMAP`.
+ $ sudo make <keyboard>:<keymap>:dfu
-Frist remove all files made in previous build,
+Note that running `make` with `sudo` is generally ***not*** a good idea, and you should use one of the former methods, if possible.
- $ make clean
+### Linux `udev` Rules
+On Linux, you'll need proper privileges to access the MCU. You can either use
+`sudo` when flashing firmware, or place these files in `/etc/udev/rules.d/`.
-then build new firmware.
-
- $ make [KEYMAP=...]
-
-Also you can always try `make clean` when you get other strange result during build.

-## USB stack: LUFA or PJRC?
-Use **LUFA**.
+### Serial device is not detected in bootloader mode on Linux
+Make sure your kernel has appropriate support for your device. If your device uses USB ACM, such as
+Pro Micro (Atmega32u4), make sure to include `CONFIG_USB_ACM=y`. Other devices may require `USB_SERIAL` and any of its sub options.
-**PJRC** stack won't be supported actively anymore. There is no reason to hesitate to use LUFA except for binary size(about 1KB lager?). But **PJRC** is still very useful for debug and development purpose.
-See also [Issue #50](https://github.com/tmk/tmk_keyboard/issues/50) and [Issue #58](https://github.com/tmk/tmk_keyboard/issues/58).
+## Unknown Device for DFU Bootloader
-## Edit configuration but not change
-You will need followings after editing `CONSOLE_ENABLE`, `NKRO_ENABLE`, `EXTRAKEY_ENABLE` or `MOUSEKEY_ENABLE` option in **Makefile**.
+If you're using Windows to flash your keyboard, and you are running into issues, check the Device Manager. If you see an "Unknown Device" when the keyboard is in "bootloader mode", then you may have a driver issue.
-### 1. make clean
-This will be needed when you edit **config.h**.
+Re-running the installation script for MSYS2 may help (eg run `./util/qmk_install.sh` from MSYS2/WSL) or reinstalling the QMK Toolbox may fix the issue.
-### 2. Remove Drivers from Device Manager(Windows)
-**Windows only.** Linux, OSX and other OS's doesn't require this. It looks like Windows keeps using driver installed when device was connected first time even after the device changes its configuration. To load proper drivers for new configuration you need to remove existent drivers from **Drvice Manager**.
+If that doesn't work, then you may need to grab the [Zadig Utility](https://zadig.akeo.ie/). Download this, find the device in question, and select the `WinUSB` option, and hit "Reinstall driver". Once you've done that, try flashing your board, again. If that doesn't work, try all of the options, until one works.
-### 3. Build with different VID:PID
-**Windows only.** If method 2. does't work fou you try this. Change Vendor ID or Product ID in **config.h** and build firmware. Windows should recognize it as whole new device and start drivers install process.
+?> There isn't a best option for which driver should be used here. Some options work better on some systems than others. libUSB and WinUSB seem to be the best options here.
-### 4. Just try other ports
-This will be useful and the easiest workaround for **Windows**.
+If the bootloader doesn't show up in the list for devices, you may need to enable the "List all devices" option in the `Options` menu, and then find the bootloader in question.
+## WINAVR is Obsolete
+It is no longer recommended and may cause some problem.
+See [TMK Issue #99](https://github.com/tmk/tmk_keyboard/issues/99).
## USB VID and PID
-You can use any ID you want with editing `config.h`. Using any presumably unused ID will be no problem in fact except for very least chance of collision with other product.
+You can use any ID you want with editing `config.h`. Using any presumably unused ID will be no problem in fact except for very low chance of collision with other product.
-For example TMK uses following numbers by default.
-```
-keyboard:
-hhkb: FEED:CAFE
-gh60: FEED:6060
-
-converter:
-x68k: FEED:6800
-ps2: FEED:6512
-adb: FEED:0ADB
-ibm4704: FEED:4704
-pc98: FEED:9898
-```
+Most boards in QMK use `0xFEED` as the vendor ID. You should look through other keyboards to make sure you pick a unique Product ID.

-## Linux udev rules
-On Linux you need proper privilege to access device file of MCU, you'll have to use `sudo` when flashing firmware. You can circumvent this with placing these files in `/etc/udev/rules.d/`.

Your toolchain is too old to support the MCU. For example WinAVR 20100110 doesn't support ATMega32u2.

+## `avr-gcc: internal compiler error: Abort trap: 6 (program cc1)` on MacOS
+This is an issue with updating on brew, causing symlinks that avr-gcc depend on getting mangled.
+
+The solution is to remove and reinstall all affected modules.
+
+```
+brew rm avr-gcc
+brew rm dfu-programmer
+brew rm dfu-util
+brew rm gcc-arm-none-eabi
+brew rm avrdude
+brew install avr-gcc
+brew install dfu-programmer
+brew install dfu-util
+brew install gcc-arm-none-eabi
+brew install avrdude
+```
+
+### avr-gcc 8.1 and LUFA
+
+If you updated your avr-gcc to above 7 you may see errors involving LUFA. For example:
+
+`lib/lufa/LUFA/Drivers/USB/Class/Device/AudioClassDevice.h:380:5: error: 'const' attribute on function returning 'void'`
+
+For now, you need to rollback avr-gcc to 7 in brew.
+
+```
+brew uninstall --force avr-gcc
+brew install avr-gcc@8
+brew link --force avr-gcc@8
+```

+### I just flashed my keyboard and it does nothing/keypresses don't register - it's also ARM (rev6 planck, clueboard 60, hs60v2, etc...) (Feb 2019)
+Due to how EEPROM works on ARM based chips, saved settings may no longer be valid. This affects the default layers, and *may*, under certain circumstances we are still figuring out, make the keyboard unusable. Resetting the EEPROM will correct this.

+If bootmagic is enabled in any form, you should be able to do this too (see [Bootmagic docs](feature_bootmagic.md) and keyboard info for specifics on how to do this).
