|
## 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 -
|
|
|
|
see reference numbers on the board.
|
|
|
|
|
|
|
|
## Testing
|
|
|
|
|
|
|
|
After running `artiq_sinara_test`:
|
|
|
|
|
|
|
|
```text
|
|
|
|
*** Testing Zotino DACs and USER LEDs.
|
|
|
|
Voltages:

|

|
|
|
|
Press ENTER when done.

|
|
|
|
Press ENTER when done.
|
|
|
|
```
|
|
|
|
|
|
|
|
1. Touch with multimeter/DC voltmeter each pair of pins from bottom to top (left pins are ground)
|
|
|
|
2. Check that respective pins have voltages as described by `artiq_sinara_test`
|
|
|
|
3. If there are [BNC/SMA-IDC adapters](./bnc_sma_idc_adapter.md), also check their voltages - they should be the same
|
|
|
|
4. Check LEDs are on

## Common problems
|
|
|
|
|
|
|
|
### High-freq audible noise and output values all near -0.1 on Zotino v1.4.2
|
|
|
|
|
|
|
|
This may happen when power-cycle is too short. Power down the crate, wait at least 30 seconds, and power up again.

### Zero voltage output on Fastino
|
|
|
|
|
|
|
|
Some Fastino may not output any voltage during testing, usually that means it has no gateware.
|
|
|
|
|
|
|
|
Another common symptom of no gateware is that no LEDs are lit up. Whereas if the gateware has been flashed, the PG and FD LEDs will be lit green.
|
|
|
|
|
|
|
|
You can flash the gateware with a standalone Kasli/Kasli-SoC:
|
|
|
|
|
|
|
|
1. Download the latest `fastino.bin` release from [quartiq/fastino](https://github.com/quartiq/fastino/releases)
|
|
|
|
2. Run `git clone https://github.com/quartiq/kasli-i2c.git` and place `fastino.bin` in the kasli-i2c directory
|
|
|
|
2. Connect the Fastino's EEM0 to any available Kasli/Kasli-SoC EEM port (**do not hot-plug**)
|
|
|
|
3. Power on the standalone Kasli/Kasli-SoC
|
|
|
|
4. Run `nix-shell -p python311Packages.pyftdi`
|
|
|
|
5. Run `cd kasli-i2c; python flash_fastino.py 0 EEM<number> write fastino.bin` where `<number>` is the EEM port number on the Kasli/Kasli-SoC side
|
|
|
|
6. If PG and FD LEDs are lit green, the Fastino is ready.
