Machine configuration fileΒΆ

The machine configuration file is where the hardware is described in terms of variables such as:

SERIAL_CONSOLES
Describe the serial console used on this machine
MACHINE_EXTRA_RRECOMMENDS
List the packages recommended during run time for this machine
UBOOT_DTB_NAME
Set the DTB file name used by U-Boot
UBOOT_CONFIG
Describe the configuration used for U-Boot on this machine
MACHINE_FEATURES
List the machine features for this machine used to configure the Yocto Project packages and tools
IMXBOOT_TARGETS
State the target name to be used with imx-boot, a critical package to the bring up of i.MX8 SoC family boards

The machine configuration file from a reference board can serve as a reminder on what variable set is important to define.

It is possible that the porting task targets a new machine configuration file. In this case, any machine related configuration should be placed in the new machine configuration file.
