    ROCK 3 >  Compute Module 3 >  Raspberry Pi CM4 IO Board

Getting Started

What you need

Necessary
  • CM4 IO main board
  • CM4 IO top board
  • One of the Storage media below:
    • microSD, larger than 8GB.
  • Power supply
    • The CM4 is powered by DC port and has a wide range of input voltage, 12V.
  • USB Keyboard and Mouse
    • With four USB-A connectors, CM4 IO can be equipped with a full sized keyboard and mouse.
  • Monitor and HDMI Cable
    • CM4 IO is equipped with a full sized HDMI connector. HDMI capable monitor is recommended.
    • HDMI EDID display data is used to determine the best display resolution. On monitors and TVs that support 1080p (or 4K) this resolution will be selected. If 1080p is not supported the next available resolution reported by EDID will be used. This selected mode will work with MOST but not all monitors/TVs.
  • Micro USB
    • If you want write image on CM4 IO from USB port , commands you need an USB Male A to Micro USB cable to connect CM4 IO and PC.
Optional

    • For flashing the image into microSD Card
  • USB type A to type Micro USB
    • Write image on CM4 IO from USB port
  • USB to TTL serial cable
    • This is needed for serial console.
  • Ethernet cable
    • CM4 IO supports Internet access via WIFI or Ethernet.
    • An Ethernet cable is used to connect your CM4 IO to a local network and the Interne
  • Audio cable
    • Audio can be played through speaker or headphones using a standard 3.5mm jack.
  • WiFi/BT Cards


Install on eMMC from USB port

CM4 supports Maskrom mode, which is a special operation mode for CPU to wait for Micro USB port command. The PC tools we use to communicate with CM4 IO in Maskrom mode are the rkdevelopment tool and AndroidTool tool. We use the rkdevelopment tool in Linux/macOS and the AndroidTool tool under Windows.

Requirement

  • CM4 IO board
  • Power adapter
  • USB Male A to Micro USB .

Install Tools&Drivers

Windows

Step 1:Install Android tool

The tool is provided in a compressed package. First, download the compressed package of this tool, and click the download link (RKDevTool_Release_v2.81.zip). After downloading, unzip it. Installation is complete.

Step 2:Install driver

Using the RK driver assistant tool to install the driver. There’s no need to connect your Rockchip device during this procedure just download and extract RKDriverAssistant.zip Then double click on DriverInstall.exe in the RKDriverAssistant directory to start the utility. If you installed the Rockchip USB drivers for any other Rockchip devices already, make sure you click “Uninstall Driver” first. RK Driver Assistant Install Uninstall.jpg

Then click “Install Driver”, the driver has finish installing.

Linux

For Linux, we build the rkdeveloptool, >=1.32, from source code. To build rkdeveloptool on a Debian based Linux distribution, follow the instruction below: Install build dependency:

 sudo apt-get install libudev-dev libusb-1.0-0-dev dh-autoreconf

Clone the source code and build:

 git clone https://github.com/rockchip-linux/rkdeveloptool
 cd rkdeveloptool
 autoreconf -i
 ./configure
 make

If you encounter compile error like below

   ./configure: line 4269: syntax error near unexpected token `LIBUSB1,libusb-1.0'
   ./configure: line 4269: `PKG_CHECK_MODULES(LIBUSB1,libusb-1.0)'

You should install pkg-config libusb-1.0

   sudo apt-get install pkg-config libusb-1.0

Then re-run

   autoreconf -i
   ./configure
   make

Now you have rkdeveloptool executable at the current directory.

 sudo cp rkdeveloptool /usr/local/bin/

MacOS

For macOS, we build the rkdeveloptool, >=1.32, from source code. To build rkdeveloptool on macOS, you need homebrew(or similar package manager) to install required packages. Install build dependency:

   brew install automake autoconf libusb lsusb

Clone the source code and build:

   git clone https://github.com/rockchip-linux/rkdeveloptool
   cd rkdeveloptool
   autoreconf -i
   ./configure
   make

If you encounter compile error like below

   ./configure: line 4269: syntax error near unexpected token `LIBUSB1,libusb-1.0'
   ./configure: line 4269: `PKG_CHECK_MODULES(LIBUSB1,libusb-1.0)'

You should install pkg-config libusb-1.0

   brew install pkg-config

Then re-run

   autoreconf -i
   ./configure
   make

Now you have rkdeveloptool executable at the current directory.

   sudo cp rkdeveloptool /usr/local/bin/

Boot the board to maskrom mode

To boot CM4 IO into maskrom mode is simple:

  • 1. Power off the board
    • remove microSD card
  • 2. Plug the USB Male A to Micro USB cable to CM4 IO port(the upper USB3 port), the other side to PC
  • 3.Press the key and hold, short the follow pins, and then disconnect the pins,release the key.

Cm4-io-maskrom.jpg

  • 4. For Linux/macOS

Now on your Linux PC, lsusb command show show the following usb devices

   Bus 003 Device 005: ID 2207:330c
  • 5. For Windows

Open device manager in your Windows PC, check the Device Manager:

RK Driver Assistant Install Usb driver.png

It means the device is in maskrom mode now.

  • 6. Now plug the eMMC module and proceed the next step to flash.

Alternatively, if you are running Android and can access ADB, you can reboot the device to loader mode `adb reboot bootloader` then use the rkdeveloptool to reset the device into maskrom mode `rkdeveloptool rd 3` or Windows AndroidTool Switch button to go to maskrom mode.


Begin Installation USB -> eMMC

Linux/macOS

On your PC, run the rkdeveloptool

   rkdeveloptool ld        # List the device
   DevNo=1	Vid=0x2207,Pid=0x330c,LocationID=305	Maskrom

Download the loader (flash helper) to init the ram and prepare the flashing environment etc. If you don't have it, you can download it from here

   rkdeveloptool db rk356x_loader_vxxxx.bin

Write the GPT image to eMMC, start to write from offset 0. you can get image from here.

   rkdeveloptool wl 0 /path/to/xxx-gpt.img

Reboot the device

   rkdeveloptool rd

Now the device should boot the new image on eMMC Please notice that when you want to erase eMMC on board, you can use this command. Get zero.img from here.

   rkdeveloptool db rk356x_loader_vxxxx.bin
   rkdeveloptool wl 0 zero.img

Windows

Double click the RKDevTool.exe and you will see the following interface: Double click this red box and modify it to image in the second row. Modify-options.jpeg

Step 1: Select Loader

If your CM4 IO is in maskrom mode and connects to PC, you can see that the program detect it Found one MASKROM Device in the red box Next, click the button in the first row on the right last columns select the loader "rk356x_xxx_ loader_ xxxxx.bin ", Select-loader-bin.jpeg Note: the loader (flash helper) is used to init the ram and prepare the flashing environment etc. If you don't have it, you can download it from here

Step 2: Select Image

Then click the right last columns to in the Image row and choose the image you want to flash.You can download the image from here Note: Normally the image name should ends with xxx-gpt.img. If the image name ends with xxx-rkupdate.img, you can not flash with this method.

Step 3: Run

Finally, click the "run" button, and you will see the content on the right. When the progress reaches 100% or show Download image OK in the red box, the download is completed. 3a-run-image.jpeg

  • ADC:X1, SARADC_IN3
  • I2S:X2, I2S1/I2S2

IO Voltage

RK3566 have three IO voltages, 1.8V/3.3V. For CM4 IO, the high level voltage of GPIO pin on 40-PIN HEADER is 3.3V.

| GPIO       | Voltage Level | Tolerance |
| ---------- | ------------- | --------- |
| SARADC_IN3    | 1.8V          | 1.98V     |

GPIO number

Rockchip RK3566 GPIO has 5 banks, GPIO0 to GPIO4, each bank has 32pins, naming as below:

GPIO0_A0 ~ A7 
GPIO0_B0 ~ B7
GPIO0_C0 ~ C7
GPIO0_D0 ~ D7
   
GPIO1_A0 ~ A7
....
GPIO1_D0 ~ D7

The GPIO number can be calculated as below, take GPIO4_D1 (PIN26 on 4-0PIN HEADER) as an example:

GPIO4_D1 = 4*32 + 3*8 + 1 = 153
(A=0, B=1, C=2, D=3)

To set GPIO4_D1 output

cd /sys/class/gpio
echo 153 > export
cd gpio153
echo out > direction
echo 1 > value     # output high
echo 0 > value     # output low
