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.
3. Connect the Fastino's EEM0 to any available Kasli/Kasli-SoC EEM port ([**do not hot-plug**](../build_test_firmware.md#operating-hints-and-warnings)).
You may skip this step if Fastino is connected within a crate.
4. Power on the standalone Kasli/Kasli-SoC and connect it to the PC via data micro-USB.
5. Run `nix-shell -p python311Packages.pyftdi`.
6. 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.
7. If PG and FD LEDs are lit green, the Fastino is ready.
Fastinos by default after power up output 10V on all channels if not driven by the test otherwise. Make sure the EEM ports are specified correctly in the JSON and the EEM cable is connected to EEM0 on the Fastino.
