Hardware Requirements​

You need to prepare the following hardware

  • reComputer R1000 x 1
  • Host Computer (Windows/Mac/Linux) x 1
  • Ethernet cable x 1
  • Power adapter (12V-24V) BYO
  • USB Type-C cable x 1

Software Requirements​

Steps for Flashing Raspbian OS​

  • Step 1. Make sure switch is set to Flash mode according to the diagram below:
Switch PositionModeDescriptionnRPI-BOOT
imageNormal modeBoot from eMMCLow
imageFlash modeBoot from USBHigh
  • Step 2. Please use the USB Type-C data cable connect to the Type-C port on the reComputer R1000, as shown in the below image,
  • Step 3. Please connect the Power Cord from the power supply to the reComputer R1000 power port.

note

The power solution utilizes a bridge rectifier diode for reverse polarity protection and is compatible with both AC and DC inputs. This ensures that regardless of how the power supply's positive and negative terminals are connected, the circuit will not be damaged. By using a bridge rectifier, the output voltage polarity remains fixed irrespective of the input DC polarity, providing effective reverse polarity protection.

Install reComputer R1000 drivers after flashing new Raspbian OS​

reComputer R1000 comes with the necessary drivers pre-installed out-of-the-box so you don't need to install any additional drivers. However, if you flash new OS by yourself, you need to install the necessary drivers separately.

tip

For install 32-bit OS driver, Please carefully follow the steps below:

The Operating System that pre-installed on reComputer R1000 is 64-bit, if you wish to install 32-bit OS please use the following method to install the DTS drivers.

Please follow the Access reComputer R1000 via SSH step, and then enter the following command:

echo arm_64bit=0 | sudo tee -a /boot/config.txt

Then continue the Install drivers after flashing new Raspbian OS process

  • Step 1. Clone the following repo in the ssh shell you have connected to reComputer R1000 from the above steps
sudo apt install git -y
git clone --depth 1 https://github.com/Seeed-Studio/seeed-linux-dtoverlays
  • Step 2. Enter the repo
cd seeed-linux-dtoverlays
  • Step 3. Type the following to install the drivers
sudo ./scripts/reTerminal.sh --device reComputer-R100x
  • Step 4. Reboot the reComputer R1000
sudo reboot

This process will ensure that your drivers are up to date before updating the firmware.

For reComputer R1000 V1.0, it need to change the /boot/firmware/config.txt file after restarting and enter the following command:

 sudo nano /boot/firmware/config.txt

Modify the final content of the file to:

  enable_uart=1
  dtoverlay=dwc2,dr_mode=host
  dtoverlay=vc4-kms-v3d
  dtoverlay=reComputer-R100x,uart2

Then restart:

  sudo reboot
