### Making your own UF2
To create your own UF2 DFU update file simply use the [Python conversion script](https://github.com/Microsoft/uf2/blob/master/utils/uf2conv.py) on a .bin file or .hex file, specifying the family as **0xADA52840**. Be sure to compile your application to start at 0x26000 (152k). If using a .bin file with the conversion script you must specify this with the -b switch.
To create a UF2 image from a .bin file:
```
uf2conv.py firmware.bin -c -b 0x26000 -f 0xADA52840
```
To create a UF2 image from a .hex file:
```
uf2conv.py firmware.hex -c -f 0xADA52840
```
## Burn & Upgrade with pre-built binaries
You can burn and/or upgrade the bootloader with either a J-link or DFU (serial) to a specific pre-built binary version
