Some Urukuls may fail with this error during testing, usually meaning that the Urukul has not been flashed with the
firmware, especially if the ID is `65535` (you will need to edit the code to check this).
Another common symptom of no firmware is that no LEDs are lit up, besides Power Good - whereas if the firmware has been flashed, the RF channels will be lit red.
You can flash the firmware yourself with a JTAG adapter:
1. Download the latest binary release from [quartiq/urukul](https://github.com/quartiq/urukul) and extract the `urukul.jed` file.
2. Connect the Urukul with the JTAG adapter to the PC and connect its EEM0 to any available Kasli/Kasli-SoC (do not hot-plug), then turn on the Kasli/Kasli-SoC.
2. Connect the Urukul with the JTAG adapter to the PC and connect its EEM0 to any available Kasli/Kasli-SoC (**do not hot-plug**), then power on the Kasli/Kasli-SoC.
3. Run `nix-shell -p xc3sprog`.
4. Run `xc3sprog -c jtaghs2 urukul.jed -m /opt/Xilinx/Vivado/<available version>/data/xicom/cable_data/digilent/lnx64/xbr/`.
5. If the last command outputs Verify: Success, then your Urukul is ready. It can also output the message
