Silence gcc > 7 type-limits warning

GCC > 7 warns that the selected type of the enum makes the comparisson
unneccesary. Since the selected enum fits in an integer, the input
parameter is casted to an integer to make the comparison valid and
asserts that the enum is within valid enum values (which we know are
monotonically growing).

Arm Ethos-U Core Driver

This repository contains a device driver for the Arm Ethos-U NPU.

Building

The source code comes with a CMake based build system. The driver is expeced to be cross compiled for any of the supported Arm Cortex-m CPUs, which will require the user to setup a custom toolchain file.

The user is also required to define CMAKE_SYSTEM_PROCESSOR for the target CPU, for example cortex-m55+nodsp+nofp. This can be done either in the toolchain file or on the command line.

$ mkdir build
$ cd build
$ cmake .. -DCMAKE_TOOLCHAIN_FILE=<toolchain> -DCMAKE_SYSTEM_PROCESSOR=cortex-m<nr><features>
$ make

License
