Board: NXP IMXRT1050-EVKB

The tables below list the device configuration for this board. The board layer for the NXP IMXRT1050-EVKB is using the software component ::Board Support: SDK Project Template: project_template (Variant: evkbimxrt1050) from NXP.EVKB-IMXRT1050_BSP.15.0.0 pack.

The heap/stack setup and the CMSIS-Driver assignment is in configuration files of related software components.

The example project can be re-configured to work on custom hardware. Refer to "Configuring Example Projects with MCUXpresso Config Tools" for information.
