# Arm semihosting |
|
|
|
This folder contain a toolchain file and a couple of examples for |
|
building OpenCV based applications that can run in an [Arm |
|
semihosting](https://developer.arm.com/documentation/100863/latest) |
|
setup. |
|
|
|
OpenCV can be compiled to target a semihosting platform as follows: |
|
|
|
``` |
|
cmake ../opencv/ \ |
|
-DCMAKE_TOOLCHAIN_FILE=../opencv/platforms/semihosting/aarch64-semihosting.toolchain.cmake \ |
|
-DSEMIHOSTING_TOOLCHAIN_PATH=/path/to/baremetal-toolchain/bin/ \ |
|
-DBUILD_EXAMPLES=ON -GNinja |
|
``` |
|
|
|
A barematel toolchain for targeting aarch64 semihosting can be found |
|
[here](https://developer.arm.com/tools-and-software/open-source-software/developer-tools/gnu-toolchain/gnu-a/downloads), |
|
under `aarch64-none-elf`. |
|
|
|
The code of the examples in the `norm` and `histogram` folders can be |
|
executed with qemu in Linux userspace: |
|
|
|
``` |
|
qemu-aarch64 ./bin/example_semihosting_histogram |
|
qemu-aarch64 ./bin/example_semihosting_norm |
|
```
