### 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.
