Non-Secure DMA350 example for FreeRTOS

DMA-350 Triggering interface

FreeRTOS example to demonstrate the DMA-350 privileged and unprivileged APIs. The privileged task demonstrates a way of using of command linking feature. The unprivileged task demonstrates the usage of the unprivileged DMA API through a simple 2D example.

Build steps

Build Secure TF-M with the following commands:

$ cmake -S <TF-M Source Dir> -B build/spe -DTFM_PLATFORM=arm/mps3/corstone310/fvp -DTFM_PROFILE=profile_small
$ cmake --build build/spe -- -j$(nproc) install

Then to build the Non-Secure app:

$ cmake -S <path_to_this_example> -B build/nspe -DCONFIG_SPE_PATH=<absolute_path_to>/build/spe/api_ns
$ cmake --build build/nspe -- -j$(nproc)
