Go to Windows Device Manager and find the keyboard (plug it in while holding down `Backspace` (`Top Right Key`)). It can be found under Human Interface Devices or under Keyboards. -2. Go to properties and the Details tab to find the hardware ID. You want the VID and the PID (code after the underscore). Plug them into HIDBootFlash and hit Find Device. -3. Use `make jj40:<keymap-name>` to generate the .hex file in the qmk basis folder. Select the .hex file in HIDBootFlash and press Flash Device. - - -## Troubleshooting - -1. Try plugging the board in while pressing `Backspace` (`Top Right Key`). This will force it - to boot only the bootloader without loading the firmware. Once this is - done, just reflash the board with the original firmware. -2. Sometimes USB hubs can act weird, so try connecting the board directly - to your computer or plugging/unplugging the USB hub. -3. If you get an error such as "Resource Unavailable" when attemting to flash - on Linux, you may want to compile and run `tools/usb_detach.c`. See `tools/README.md` - for more info. - -## Recovery -If you flash a bad hex (e.g. you have a V1 board without RGB and compile/flash blindly without editing your rules.mk), your jj40 is now semi-bricked and you're stuck unless you have access to an ISP. The [ISP Flashing Guide](https://docs.qmk.fm/#/isp_flashing_guide) contains very good (but somewhat generalized) information. However, the instructions below should get you up and running provided you have an Arduino or clone. - -### Arduino Setup -1. Upload the ArduinoISP sketch onto your Arduino board (https://www.arduino.cc/en/Tutorial/ArduinoISP). -2. Wire the Arduino to the jj40. Match the data pins on the Arduino to those on the jj40. "RST" usually goes to D10 on the Arduino. I didn't need a capacitor when using my Uno. - -3. Get a working bootloader from https://blog.winkeyless.kr/m/152. The file is called "main.hex" from the archive called "ps2avrGB_bootloader_161215.zip" Copy "main.hex" to your qmk folder. -4. Burn the bootloader with the following command -` avrdude -b 19200 -c avrisp -p atmega32 -v -e -U hfuse:w:0xD0:m -U lfuse:w:0x0F:m -U flash:w:main.hex:i -P comPORT` -Change `comPORT` to whatever port is used by the Arduino (e.g. `com11` in Windows or `/dev/ttyACM0` in Linux). Use Device Manager in Windows to find the port being used. Use `ls /dev/tty*` in Linux. -5. If this process is successful, you should now be able to upload normally. +See the [build environment setup](https://docs.qmk.fm/#/getting_started_build_tools) and the [make instructions](https://docs.qmk.fm/#/getting_started_make_guide) for more information.
