See [build environment setup](https://docs.qmk.fm/#/getting_started_build_tools) then the [make instructions](https://docs.qmk.fm/#/getting_started_make_guide) for more information.
Out of the box the tada68 uses a .bin firmware file instead of a .hex like other custom keyboards. By default QMK will build and copy the correct .bin file for you. If for some reason you need a hex file instead, you can add `:hex` to your make command, or look inside `qmk_firmware/.build` to find the hex file.
*When flashing the keyboard from a Mac, you must delete some files that are automatically created by the operating system in order to prevent bricking your keyboard. Original information from /u/pawlwall from https://www.reddit.com/r/MechanicalKeyboards/comments/520cov/using_an_originative_tada86_on_a_mac/*
1) from the `qmk_firmware\` directory run:
```
$ make tada68:default:flashbin
```
2) Connect your keyboard to your Mac, hit the reset button on the bottom of the TADA, the lights will start flashing.
3) You'll see a new drive on your computer called TADA68. Backup the original factory `FLASH.BIN` file that's inside it.
4) Open the terminal and cd to the folder where the keyboard has been mounted
`cd /Volumes/TADA68\ /`
5) Copy over your new firmware to the keyboard
`cp -r <path to your qmk_firmware folder>/FLASH.bin .`
6) Remove files that MacOS automatically created which interfere with the keyboard
*Use these instructions at your own risk. Mount settings originally found at https://www.reddit.com/r/MechanicalKeyboards/comments/8e2nnp/help_problems_flashing_firmware_on_tada68_from/*
1) from the `qmk_firmware\` directory run:
```
$ make tada68:default:flashbin
```
2) Connect your keyboard to Windows computer, hit the reset button on the TADA, the lights will start flashing.
3) A new entry should appear at `/dev/sd*`. Mount the board using this command:
```
mount -t vfat -o rw,nosuid,nodev,relatime,uid=1000,gid=1000,fmask=0022,dmask=0022,codepage=437,iocharset=iso8859-1,shortname=mixed,showexec,utf8,flush,errors=remount-ro,uhelper=udisks2 <pathtodevice> /mnt/tada68
```
4) Back up the original firmware
`mv /mnt/tada68/FLASH.BIN ~`
5) Copy over your new firmware to the keybaord
`cp <path to your qmk_firmware folder>/FLASH.bin /mnt/tada68`
5) *Do not eject the USB device.* Hit ESC on the keyboard. The lights will stop flashing and your firmware is loaded!
