Running a fixed virtual platform based on Arm(R) Corstone(TM)-300 software

This target makes use of a fixed virtual platform (FVP) based on Arm Corstone-300 software.

Building the Corstone-300 based target has the following dependencies:

  • Arm Ethos-U Core Platform
    • Arm Ethos-U Core Platform provides the linker file as well as UART and retarget functions.
  • CMSIS
    • CMSIS provides startup functionality, e.g. for setting up interrupt handlers and clock speed.

Both these repositories are downloaded automatically by the build process in TFLM.

General build info

You can compile the Corstone-300 target for multiple Cortex-M CPUs. See below.

Required parameters:

  • TARGET: cortex_m_corstone_300
  • TARGET_ARCH: cortex-mXX. Replace XX with either of the options in the Corstone-300 makefile

How to run

Note that Corstone-300 emulates a Cortex-M55 system, but it is backwards compatible. This means one could run code compiled for e.g. a Cortex-M7.
