2 Boardcon EM3568 SBC

Contents

2.1 Board Overview

Boardcon EM3568 single board computer is based on Rockchip RK3568 and designed specifically for AIoT and industrial applications with 2 GiB RAM (up to 8 GiB), 8 GB storage (up to 128 GB), optional Wi-Fi and Bluetooth, Camera and 4G modules. The SBC features two Gigabit Ethernet port to meet the high-speed network requirements, as well as High-speed expansion interface such as SATA 3.0, USB 3.0 port. Multi-screen different display is also supported, and EM3568 integrates eDP/MIPI/LVDS/RGB interfaces. In addition, the SBC provides some general data interfaces such as UART (TTL), RS485 and CAN.

Target board.

[2]

Target YAML-file located in the kas/targets directory.

[3]

Target machine name stored in the MACHINE BitBake variable for selected Target YAML.

[4]

Recipes that will be built by default for the target. In Section 2.2.2, you can find list of supported recipes for the target images, which you can build in addition to the default recipes using optional --target option in build command (see Section 2.3).

[5]

External or internal data storage where the TanoWrt operating system is running.

	tanowrt-image-full-swu	All	Standard TanoWrt image and firmware upgrade image. When building this image, tanowrt-image-full will also be built as dependency.
	tanowrt-image-full-swu-factory	boardcon-em3568-emmc.yml	Factory installation image for standard TanoWrt image. When building this image, tanowrt-image-full and tanowrt-image-full-swu will also be built as dependencies.

[7]

Image recipe name. This name can be used as argument for --target build command option (see Section 2.3 section).

2.3 Build

Please read the common information on how to perform a TanoWrt images build and preparing the build environment in section “Building TanoWrt”.

See also

• See section Section 2.2.1 to select the required target YAML file (<target-yml>).

• See section Section 2.2.2 to select the required root filesystem image recipe (<target-recipe>).

• See section Section 2.5 for detailed information about the produced build artifacts.

2.3.1 Examples

2.3.1.1 Build Default Images for Boardcon EM3568 Board

For microSD Card

$ kas build targets/kas/boardcon-em3568-sd.yml

Default images will be produced to boot and run from the microSD card on the Boardcon EM3568 target board.

For Internal eMMC Flash

$ kas build targets/kas/boardcon-em3568-emmc.yml

An initial factory installation image will be generated, intended to run from the microSD card. The installer image will install the default image to the internal eMMC flash memory and further the Boardcon EM3568 board will boot and run from the eMMC flash memory.

2.4 Partitioning Layouts

Images for Boardcon EM3568 board using default partitions layouts described here.

New files, compared to the build for the SD card are highlighted. These files are required for building initial factory installation image for SD card (see Writing Image to eMMC Flash). Initial factory installation image is required for writing TanoWrt firmware to internal eMMC flash using small installation system bootable from SD card.

2.6 Writing Images

2.6.1 Writing Image to microSD Card

No special information about writing images to microSD card for Boardcon EM3568 board. See common instructions in Writing Images to SD Card or USB Flash Drive section.

Examples

Writing factory installation image for the boardcon-em3568-emmc.yml target to the microSD card /dev/mmcblk1:

$ dd if=tanowrt-image-full-swu-factory-boardcon-em3568-emmc.sdcard.img of=/dev/mmcblk1

Writing bootable image for the boardcon-em3568-sd.yml target to the microSD card /dev/mmcblk1:

$ dd if=tanowrt-image-full-boardcon-em3568-sd.sdcard.img of=/dev/mmcblk1

2.6.2 Writing Image to eMMC Flash

For the initial flashing of the internal eMMC memory it is recommended to use the special image of the initial factory installation. If you choose a build target (see Build Targets for details) that assumes using the factory installation image for the initial flashing of the device, a factory installation image (<rootfs-image>-swu-factory-<MACHINE>.sdcard.img) will be automatically generated during the build process (see Build). To write the factory installation image to a SD card, follow the instructions from Writing Images to SD Card or USB Flash Drive section.

When you boot device from the prepaired SD card with factory installation image the installation of TanoWrt to the internal eMMC flash memory will be done automatically. The detailed installation log is available on the debug UART. After the installation is complete, the board will reboots automatically. When the device is rebooted, the installed system will be booted from the internal eMMC flash memory.

Caution

Be aware that during the installation all existing data on the internal eMMC flash memory will be permanently lost.

2.7 Booting and Running

2.7.1 Booting from SD Card

1. Insert the micro SD card to the board.

2. Connect the power cable to the DC input connector.

3. Boardcon EM3568 will boot.

4. (Optional) Use a USB to TTL serial cable to make a connection between your PC and Boardcon EM3568. See Serial Console section for details.

5. Log in to system using default credentials.

Attention

The internal eMMC flash memory must be empty in order to perform a boot from the SD card. See Erasing Internal eMMC Flash section for details about erasing internal eMMC flash.

2.7.2 Booting from Internal eMMC Flash

1. Connect the power cable to the DC input connector.

2. Boardcon EM3568 will boot.

3. (Optional) Use a USB to TTL serial cable to make a connection between your PC and Boardcon EM3568. See Serial Console section for details.

4. Log in to system using default credentials.

2.7.3 Erasing Internal eMMC Flash

You can erase the internal eMMC flash memory in the following ways:

• Linux command line;

• U-Boot command line;

• special utilities and USB connection with PC.

Linux CLIU-Boot CLIUSB Connection with PC

Erasing eMMC Using Linux Command Line

If the device has a bootable Linux system, you can erase the eMMC by the following command entered in the Linux terminal:

[root@tanowrt ~]# dd if=/dev/zero of=/dev/mmcblk0 bs=1k count=32768

Note that if the Linux distribution flashed on the eMMC flash memory is not TanoWrt, the device name of the eMMC flash memory may be different. You can usually find out the real device name by analysing the system boot log by running the command dmesg. For example:

[root@tanowrt ~]# dmesg | grep mmcblk
[    2.396143] mmcblk0: mmc0:0001 8GTF4R 7.28 GiB

2.9 Default Network Configuration

By default Ethernet ports 1 (eth0 interface) and 2 (eth1 interface) are joined into a bridge (br-lan interface). Bridge (br-lan) configured to obtain IP configuration via DHCP client. To see obtained IP configuration use the following command:

[root@tanowrt ~]# ifstatus lan | jsonfilter -e '@["ipv4-address"][0].address'
192.168.0.42

In this example, the device got the IP address 192.168.0.42 via DHCP.

By default, RSTP is enabled on the br-lan bridge.

Also you can connect to the board using USB network connection (usb0 interface). USB network interface configured with static IP address 192.168.128.1 with enabled DHCP server with pool with single IP address for client (your PC) 192.168.128.100.

WiFi module and 3G/GPRS modules currently are not supported in TanoWrt.

2.10 Web User Interface
