ConnectCore 6 Linux BSP Reference Manual

Platform Device Tree Files

The DTS file for the 

ccimx6adpt

 platform can be found in the kernel source code tree under: 

arch/arm/boot/dts/imx6-ccimx6adpt-ldo.dts

This DTS file includes other DTS and DTSI file in the same path.

Unsupported Devices

The following devices or interfaces are not supported in the BSP of the Early Availability (EA) Kit:

• ADC

• Camera

•  LCD parallel interface

• Power management

•  PWM (on CPU)

Bluetooth

Bluetooth (if supported by the Atheros wireless chip variant) is connected to UART2.

The MAC address of the Bluetooth interface is taken from U-Boot environment variable 

btaddr

which is populated by U-Boot on the Device Tree before booting Linux.

There is no generic Device Tree binding for the Bluetooth interface. Digi has created a 

bluetooth entry node to pass the driver the MAC address (filled-in by U-Boot) and the power 
down GPIO.

Note:  

Due to a HW bug in the module, Bluetooth is not supported in version 1 of the 

ConnectCore 6 module.

CAN Bus

The CPU has two Flexcan CAN ports. The CAN support is based on the SocketCAN stack. For 

more information about this project, documentation, and API, please refer to

FlexCAN Device Tree binding is described at
