The Linux kernel shipped on Digi Embedded for Android contains a default configuration that supports all the hardware available on the ConnectCore 8X and its development board. When you design a custom carrier board, it is common to modify the Linux kernel source tree to:
-
enable support for drivers on the Linux configuration to support hardware on your carrier board.
-
add new drivers that don’t exist on the current kernel source tree, or modify existing ones.
-
modify the device tree to:
-
enable/disable interfaces.
-
change the IOMUX of ConnectCore 8X pads.
-
add entries for new hardware on your carrier board.
