The ConnectCore 6 is shipped without a default operating system loaded. Only U-Boot is flashed in the device. This step demonstrates how to install Digi Embedded Yocto in your ConnectCore 6.
1. Establish a serial connection with your device
Open a serial connection with the device. You can use any serial terminal program such as Tera Term, Minicom, CoolTerm, or HyperTerminal.
| PuTTY terminal program is not recommended due to an incompatibility with the USB/serial driver. |
Open a serial connection with the following settings:
| Parameter | Value |
|---|---|
Port |
Serial port where the device is connected |
Baud rate |
115200 |
Data bits |
8 |
Parity |
None |
Stop bits |
1 |
Flow control |
None |
2. Download the firmware
Download the firmware images from the following location:
3. Program the firmware
There are multiple methods of programming the firmware to the target:
-
Use a microSD card to install the firmware directly in the target.
-
Use USB mass storage to install the firmware directly in the target.
Program the firmware using uSD card
-
Decompress the zip file.
-
Place the decompressed files in the root of a FAT-formatted microSD card and insert it in the microSD socket of the board.
-
Reset the device by pressing the reset button on the board and immediately press any key in the serial terminal to stop the auto-boot process. The U-Boot bootloader prompt displays:

Install the firmware into the internal eMMC, executing the following command:
=> run install_linux_fw_sd
-
Once the firmware is installed, the device boots automatically. The default username is root with no password.
During installation, error messages appear when the installation process attempts to override MAC addresses. These messages are expected.

Program the firmware using USB mass storage
Follow these steps to install Yocto in the device:
-
Decompress the zip file.
-
Place the decompressed files in the root of a FAT-formatted USB mass storage and insert it in the USB host connector of the board.
-
Reset the device by pressing the reset button on the board and immediately press any key in the serial terminal to stop the auto-boot process. The U-Boot bootloader prompt displays:
