# Frequently Asked Build Questions
|
|
|
|
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.
|
|
|
|
## 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:
|
|
|
|
$ sudo dfu-programmer atmega32u4 erase --force
|
|
$ sudo dfu-programmer atmega32u4 flash your.hex
|
|
$ sudo dfu-programmer atmega32u4 reset
|
|
|
|
or just:
|
|
|
|
$ sudo make <keyboard>:<keymap>:dfu
|
|
|
|
Note that running `make` with `sudo` is generally ***not*** a good idea, and you should use one of the former methods, if possible.
|
|
|
|
### 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/`. Once added run the following:
|
|
```console
|
|
sudo udevadm control --reload-rules
|
|
sudo udevadm trigger
|
|
```
|
|
|
|
**/etc/udev/rules.d/50-atmel-dfu.rules:**
|
|
```
|
|
# Atmel ATMega32U4
|
|
SUBSYSTEMS=="usb", ATTRS{idVendor}=="03eb", ATTRS{idProduct}=="2ff4", MODE:="0666"
|
|
# Atmel USBKEY AT90USB1287
|
|
SUBSYSTEMS=="usb", ATTRS{idVendor}=="03eb", ATTRS{idProduct}=="2ffb", MODE:="0666"
|
|
# Atmel ATMega32U2
|
|
SUBSYSTEMS=="usb", ATTRS{idVendor}=="03eb", ATTRS{idProduct}=="2ff0", MODE:="0666"
|
|
```
|
|
|
|
**/etc/udev/rules.d/52-tmk-keyboard.rules:**
|
|
```
|
|
# tmk keyboard products https://github.com/tmk/tmk_keyboard
|
|
SUBSYSTEMS=="usb", ATTRS{idVendor}=="feed", MODE:="0666"
|
|
```
|
|
**/etc/udev/rules.d/54-input-club-keyboard.rules:**
|
|
|
|
```
|
|
# Input Club keyboard bootloader
|
|
SUBSYSTEMS=="usb", ATTRS{idVendor}=="1c11", MODE:="0666"
|
|
```
|
|
|
|
**/etc/udev/rules.d/55-caterina.rules:**
|
|
```
|
|
# ModemManager should ignore the following devices
|
|
ATTRS{idVendor}=="2a03", ENV{ID_MM_DEVICE_IGNORE}="1"
|
|
ATTRS{idVendor}=="2341", ENV{ID_MM_DEVICE_IGNORE}="1"
|
|
```
|
|
|
|
**Note:** ModemManager filtering only works when not in strict mode, the following commands can update that settings:
|
|
```console
|
|
sudo sed -i 's/--filter-policy=strict/--filter-policy=default/' /lib/systemd/system/ModemManager.service
|
|
sudo systemctl daemon-reload
|
|
sudo systemctl restart ModemManager
|
|
```
|
|
|
|
**/etc/udev/rules.d/56-dfu-util.rules:**
|
|
```
|
|
# stm32duino
|
|
SUBSYSTEMS=="usb", ATTRS{idVendor}=="1eaf", ATTRS{idProduct}=="0003", MODE:="0666"
|
|
# Generic stm32
|
|
SUBSYSTEMS=="usb", ATTRS{idVendor}=="0483", ATTRS{idProduct}=="df11", MODE:="0666"
|
|
```
|
|
|
|
**/etc/udev/rules.d/57-bootloadhid.rules:**
|
|
```
|
|
# bootloadHID
|
|
SUBSYSTEMS=="usb", ATTRS{idVendor}=="16c0", ATTRS{idProduct}=="05df", MODE:="0666"
|
|
```
|
|
|
|
### 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.
|
|
|
|
## Unknown Device for DFU Bootloader
|
|
|
|
Issues encountered when flashing keyboards on Windows are most often due to having the wrong drivers installed for the bootloader, or none at all.
|
|
|
|
Re-running the QMK installation script (`./util/qmk_install.sh` from the `qmk_firmware` directory in MSYS2 or WSL) or reinstalling the QMK Toolbox may fix the issue. Alternatively, you can download and run the [`qmk_driver_installer`](https://github.com/qmk/qmk_driver_installer) package manually.
|
|
|
|
If that doesn't work, then you may need to download and run Zadig. See [Bootloader Driver Installation with Zadig](driver_installation_zadig.md) for more detailed information.
|
|
|
|
## 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 low chance of collision with other product.
|
|
|
|
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.
|
|
|
|
Also see this.
|
|
https://github.com/tmk/tmk_keyboard/issues/150
|
|
|
|
You can buy a really unique VID:PID here. I don't think you need this for personal use.

## BOOTLOADER_SIZE for AVR
|
|
Note that Teensy2.0++ bootloader size is 2048byte. Some Makefiles may have wrong comment.
|
|
|
|
```
|
|
# Boot Section Size in *bytes*
|
|
# Teensy halfKay 512
|
|
# Teensy++ halfKay 2048
|
|
# Atmel DFU loader 4096 (TMK Alt Controller)
|
|
# LUFA bootloader 4096
|
|
# USBaspLoader 2048
|
|
OPT_DEFS += -DBOOTLOADER_SIZE=2048
|
|
```

## `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.
|
|
|
|
[Planck rev6 reset EEPROM](https://cdn.discordapp.com/attachments/473506116718952450/539284620861243409/planck_rev6_default.bin) can be used to force an eeprom reset. After flashing this image, flash your normal firmware again which should restore your keyboard to _normal_ working order.
|
|
[Preonic rev3 reset EEPROM](https://cdn.discordapp.com/attachments/473506116718952450/537849497313738762/preonic_rev3_default.bin)
|
|
|
|
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).
