## 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 -
