Crankk official guide for onboarding a Linxdot (RK3566) Gateway

1) Flash the CrankkOS image to the Linxdot’s eMMC
2) Local Dashboard setup
3) User Dashboard setup

Here are a few things you might need for this guide: USB C cable

To follow this guide, please make sure you have the
rockchip-based version of the Linxdot gateway.

If you’re considering dual mining Helium, please remember that you need to onboard it with Helium first.
The easiest way to distinguish between these two variations is by inspecting the rear side of your device, where the ports are situated.
You can identify Rockchip gateways by the presence of
a ‘BT Pair‘ button located near the antenna connector, while CM4 units lack this feature.

In this guide, we will walk you through the process of flashing the CrankkOS image onto your Linxdot gateway using a Windows OS PC.

1. Download the CrankkOS image.

Please follow this link to download the CrankkOS image for Linxdot.

All CrankkOS images.
Once the download is complete, extract the contents of the downloaded image file.
Also download the bootloader, an essential component for the later stages of this guide.2. Download and Install the Rockchip Flashing Tools.
For this step there is no need to connect your Linxdot device to your PC yet.
Rockchip Flashing Tools are available for Windows/Linux/MAC OS.
For Windows users, download the latest recommended version of the tools. Follow the instructions provided to install the tools. Make sure to install RKDriverAssistant as the first step.
Then please restart your PC.

2. Connect the Linxdot to your PC via use C cable
Use a USB C cable to connect the Linxdot to your PC.
The port is located on the back of the gateway. For now, keep the gateway powered off.

3. Flash the unzipped CrankkOS image to the eMMC
Run RKDevTool.exe to start the flashing tools.

Our goal here is to erase the flash memory and then install the CrankkOS image.
This is how it’s going to look the tool interface, before the procedure:

Now, while the gateway is powered off press and hold the
BT-Pair (the same function as Recovery button from Bobcat guide) button and then insert the power cable into the Linxdot.
If the procedure is successful, you will receive a message indicating Found One Loader Device.

Navigate to Advanced Function and select Flash.
Click on EraseAII button and wait until its 100% completed.
Once finished, remove the power cable and again hold
BT-Pair button and insert the power cable back to the device. If the Linxdot can’t be found, restart your PC and try again.

4. Flash the CrankkOS image

After the reboot is finalized, reopen RKDevTool.exe.

Please note that this will erase all the previous information, stored on the Linxdot.

Select Download image
Make sure you are in Maskrom mode.
Enable Write by Address.
Choose the correct Loader and image files,by clicking on the boxes under the three dots. Please make sure you have selected the unzipped .img file.
Double-check all the settings, ensuring everything is in order. Make sure the EMMC is present in the line 2 in the Storage tab, as shown on the screenshot. Confirm that the Address is set to 0, and then press Run.

Upon completion of the flashing process, disconnect the USB C cable and restart the gateway.

If, for any reason, the flashing procedure fails, you can begin again from Step 5. Flash the unzipped CrankkOS image to the eMMC

2) Local Dashboard setup

5. Log in to the Local Dashboard.
If you have any VPN enabled on your PC, please turn it off.
Now check your router to find the gateway IP address.
If you are unsure how to do this, you can use free tools like Advanced IP Scanner to help you out. Check the MAC address of your gateway to find the correct IP address.

Once you have the LAN IP address of your gateway, open
a new browser tab from a PC on the same network and paste the IP followed by :17080
http://192.168.0.243:17080
When logging in for the first time, you do not need to enter any credentials, just press Sign in.

You will be prompted to change your Dashboard password.

Please do so in the Settings tab.

6. Set up the gateway.
Go to the Info tab > Setup Gateway

Copy your Gateway ID, as we will need it later.
Select the Image that is installed on your gateway (Crankk / Helium / Nebra), Model and Region* (EU868 / AU915 / US915).

Turn on the Packet Forwarder.
If you are currently mining or planning to mine Helium, leave the Forwards to box unchanged as shown in the screenshot.
If you don’t wish to mine Helium, leave only 127.0.0.1:1700
Hit Save.
Your gateway will restart automatically. Please wait a few minutes while it loads.

7. Double mining.
If you want to participate in Double mining, you can install Helium from here:

8. Import your secret key.
Hint: If you don’t have your secret key saved, you can go to the User Dashboard >Wallets> find the correct wallet> use the three dots to reveal the secret key.

Navigate to the Wallet section in the Local Dashboard and enter your secret key, keeping the following in mind:

• Please ensure that you copy and paste the secret key exactly as it is, without any spaces or other symbols
• Please double-check that it is the correct secret key and that it does not belong to another gateway
• Please also note that your secret key is different from your wallet address/public key starting with k:

Hit Save.
If you have entered the correct secret key, then you will see your k: wallet address displayed in the Wallet field.

3) User Dashboard setup

9. Assign your gateway ID to a wallet in the User Dashboard.
Visit https://dashboard.crankk.io and sign in into your account.
Navigate to the Wallets section and select the wallet that you want to use for your software license activation. Please note that a positive KDA balance in your wallet is required for the successful assignment of the gateway.
Assign your gateway ID to the chosen wallet by clicking on the Assign button. If you don’t see such a button, it means you haven’t purchased a software license for this wallet.

Select your gateway Model, copy and paste your Gateway ID (please double-check that it is correct) and hit the Submit button.

Please wait a few minutes to allow the changes to sync to the blockchain.

10. Participate in Proof-of-Trust as PoNP node

Network Participation is a mandatory requirement for all gateways onboarded into Crankk, in order to receive rewards. It requires staking $100 worth of CRKK tokens.
Those funds remain yours, and if you decide to discontinue participation, you can fully withdraw them after a period of one year.

If you don’t have those tokens, just transfer an equal amount of KDA coins to your wallet. Then, use the dashboard’s DEX to swap them for CRKK tokens. After swapping, make sure there’s enough KDA in your wallet left to cover transaction fees.

Be cautious, especially if it’s your first time using a DEX. A recommended approach is to begin trading with small amounts.

To complete this process:

⦁ Log in to the User Dashboard.
⦁ Navigate to Gateways and select your specific gateway.
⦁ Click on Proof-of-Trust.
⦁ Next to the “Network Participation” tab, you will find the current amount of CRKK tokens required for staking. Simply press the green Participate button.
It’s important to note that the staking value remains constant at $100. The only variable is the quantity of CRKK tokens that need to be staked. If you lack the necessary tokens for staking, our DEX offers the option to exchange KDA coins for CRKK tokens.

11. Set your gateway location

To set your gateway location you need to:
⦁ Navigate to your gateway in the User Dashboard.
⦁ Scroll down below the Rank Percentage section until you find the Location tab.
⦁ Unlock your wallet by entering the correct password.
⦁ Click on Set Location.
⦁ Zoom out using the scroll wheel on your mouse.
⦁ Select the desired gateway location.
⦁ Click Submit.
