If you require a slightly different configuration from the one that is shipped by default. This post outlines (in short) the required steps.

Requirements:

- GNU/Linux computer
- CanFace
- FluxGrip

I will refer heavily to the [FluxGrip: Quickstart Guide](https://forum.zubax.com/t/fluxgrip-quickstart-guide/2335).

## Step 1: Update firmware

### 1. Connect to FluxGrip using CanFace

- Execute the steps outlined for [Preparation](https://forum.zubax.com/t/fluxgrip-quickstart-guide/2335#p-5233-preparation-2)
- Execute the steps outlined for [Monitoring](https://forum.zubax.com/t/fluxgrip-quickstart-guide/2335#p-5233-monitoring-3)

### 2. Trigger firmware update

- Execute the steps outlined for [Firmware update](https://forum.zubax.com/t/fluxgrip-quickstart-guide/2335#p-5233-firmware-update-11)

After a successful update (takes roughly 50 minutes); the monitor window should display the updated hash (`18b37a5cc107aeae`) for the firmware:

## Step 2: Set registers

**Note: this is a customer-specific setting, don’t change these registers unless Zubax has recommended this!**

```auto
cd ~/fluxgrip_demo
source ./my_env.sh
# Set configuration registers
yakut register-access <NODE_ID> boost.period_rab_lab_oab '3000 2000000 40000 20000 354000 30000000 1000000' 
# Reboot so new config values are loaded
yakut cmd <NODE_ID> restart
# After the reboot, you can verify if the registers have been set correctly by reading
yakut register-access <NODE_ID> boost.period_rab_lab_oab

```

Tip: Node ID can be seen from `yakut monitor` window
