# Flashing custom gateware

Follow the same instructions as the Screamer R02: [Flashing custom gateware](/fpga-devices/devices/screamer-pcie-r04/flashing-custom-gateware.md).

### Correcting for Update Port

The RaptorDMA uses a unique update port identifier. In order to use OpenOCD to flash the device over it's update port, you will need to modify the **FTDI\_VID\_PID** entry in the OpenOCD CFG file.

```
ftdi_vid_pid 0x0403 0x6010
```

Here, we are specifying the USB Device ID for your Update Port.
