## Common problems
### Urukul AD9912 product id mismatch
```pycon
ValueError: Urukul AD9912 product id mismatch
```
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).
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.
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
```shell
*** buffer overflow detected ***: terminated
Aborted (core dumped)
```
, which is okay if `Verify: Success` was also emitted.
### no valid window/delay
```pycon
ValueError: no valid window/delay
```
Check with the customer to see if synchronization is necessary, and disable it if it is not.
In any case, simply restart the test.

Fastino uses two physical EEM channels, but in the JSON file there should be only one channel specified,
and it should be the one connected to Fastino's EEM0.
## Setup
Connect the BNC/SMA-IDC adapters to the Zotino/Fastino with 26-pin cable if needed by customer. Be aware of the ports order -
