opencv_samples

There are OpenCV samples copied from opencv/samples/cpp and adopted a little ro run on Embox. These samples are located in cmds/ folder. Images for testing purposes are located in data_samples/. Embox's configurations are located in templates/.

You can run these sample on Embox (qemu, stm32) and on Linux (your PC).

Running on Embox

You need to have both repos cloned - embox and opencv_samples.

$ cd embox/
$ make ext_conf EXT_PROJECT_PATH=<path-to>/opencv_samples

Now templates are available:

$ make confload
...
ext_project/opencv_samples/stm32f769i-discovery
ext_project/opencv_samples/stm32f769i-discovery-extmem
ext_project/opencv_samples/arm-qemu

QEMU

$ make confload-ext_project/opencv_samples/arm-qemu
$ make // you can optionally pass -j<n> to speed up build

Run:

./scripts/qemu/auto_qemu

STM32F769I-Discovery

You can run some samples from internal ROM (2 MB):

$ make confload-ext_project/opencv_samples/stm32f769i-discovery
$ make // you can optionally pass -j<n> to speed up build

You can also run samples from internal QSPI (64 MB):

$ make confload-ext_project/opencv_samples/stm32f769i-discovery-extmem
$ make // you can optionally pass -j<n> to speed up build

Getting OpenOCD

You will need OpenOCD >= 0.11.0. You can download it here.

Flash and run Embox

Start OpenOCD. If you built OpenOCD from sources:

$ cd <path to openocd>/tcl

Pass the corresponding *.cfg to openocd:

$ sudo ../src/openocd -f board/stm32f769i-disco.cfg

Then go to embox/ and run:

./scripts/gdb_run_stm32f7_qspi.sh

Embox will be loaded and you can call commands from conf/start_script.inc.
