### Zero voltage output on Fastino ### Zero/meaningless voltage output on Fastino
Some Fastino may not output any voltage during testing, usually that means it has no gateware. Some Fastino may not output any meaningful voltage during testing, usually that means it has no gateware flashed.
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. 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: You can flash the gateware with a Kasli/Kasli-SoC, be it in the crate or standalone (no specific gateware needed for Kasli/SoC):
1. Download the latest `fastino.bin` release from [quartiq/fastino](https://github.com/quartiq/fastino/releases) 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. 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. 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)).
3. Power on the standalone Kasli/Kasli-SoC You may skip this step if Fastino is connected within a crate.
4. Run `nix-shell -p python311Packages.pyftdi` 4. Power on the standalone Kasli/Kasli-SoC and connect it to the PC via data micro-USB.
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 5. Run `nix-shell -p python311Packages.pyftdi`.
6. If PG and FD LEDs are lit green, the Fastino is ready. 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.
