Hardware requirements

Hardware requirements#

  • Mini/micro USB cable

  • MIMXRT1180-EVK board

  • Personal Computer

Board settings#

The mcuboot binary must be processed by SPSDK tools to allow ROM code to boot it from flash. If this is not done automatically during build/postbuild it needs to be done manually. When using NXP tools such as MCUXpresso IDE or MCUXpresso Secure Provisioning Tool this should be done automatically by the tool.
