Requirements

N6Cam

...

Power

The N6Cam is powered through the USB-C connector on the IO board (3), providing a UVC stream.

Debug

The debug connector (2) provides a standard STDC14 interface to plug a debugger.

Boot Mode

The boot selector switch (1) selects the board's operating mode. Facing the N6Cam from the front (camera):

...

Switch to the left: Development mode.

...

...

Hardware Tools

To debug and flash new firmware you’ll need either one of the following:

• 1 x STLink-V3 programmer, or…

• 2 x STLink-V3MINIE programmer

Note:

• Both options include the STDC14-STDC14 flat cable used to program the N6Cam.

...

Toolchain

...

• STM32 tools must be included on the system PATH:

  • STM32CubeIDE.:
    By default: C:\ST\STM32CubeIDE_1.17.0

  • STM32CubeProgrammer.:
    By default: C:\Program Files\STMicroelectronics\STM32Cube\STM32CubeProgrammer\bin 

Compiling the demo

Prepare environment

1. Open a terminal in the sources root folder

2. Create a virtual environment for development:

   Code Block
   language bash
   python -m venv .venv

3. Activate the environment:

   1. Linux:

      Code Block
      language bash
      . .venv/bin/activate

   2. Windows:

      Code Block
      language bash
      .venv\Scripts\activate.bat

4. Install the module requirements:

   Code Block
   language bash
   python -m pip install -U pip setuptools wheel -r requirements.txt

Compile using scripts

1. Open a terminal in the sources root folder

2. Activate the Python environment as shown in https://siana-systems.atlassian.net/wiki/spaces/N6Cam/pages/edit-v2/3919970305#Prepare-environment

3. Build the binaries running:

   Code Block
   language bash
   inv release-binaries

4. The binaries should be available now in: <ROOT>\RELEASE\SIANA.N6Cam.BSP-Binaries-<VERSION>\Binaries

Compile using IDE

...

Add the above paths to your system environment variables.

BSP Source

The following steps assume that you have unzipped the N6Cam BSP source package, which looks like:

...

This working folder will be considered as <ROOT> in the following instructions.

Compiling the BSP

Follow these steps to compile:

1. Open the STM32CubeIDE

2. Go to File > Import...:

   Image RemovedImage Added

   1. (1) Select General > Existing Projects into Workspace

   2. (2) Click Next.

3. Find and import the projects:

   Image RemovedImage Added

   1. (1) Click Select root directory

   2. (2) Browse for <ROOT>\N6Cam.BSP\STM32CubeIDEthe sources <ROOT> folder

   3. (3) Select all projects (FSBL, and Standalone)

   4. (4) Click Finish

4. Once loaded, your project should look like this:

   Image RemovedImage Added

5. Build both FSBL and Standalone using the Release “Release” profile

6. The generated binaries can be located at:

   1. FSBL: <ROOT>\Sources\STM32CubeIDE\FSBL\Release\Siana.N6Cam.BSP.FSBL.hex

   2. Standalone: <ROOT>\Sources\STM32CubeIDE

   . Specifically:

   1. FSBL: FSBL\Release\Standalone\Release\Siana.N6Cam.BSP.Standalone.hex

Loading & running the demo

The BSP comes with the demo that is preloaded when you purchased the N6Cam. This demo consists of a people-detector model and a vider streamer over USB, see the Intro (unboxing).

Signing binaries

Before loading the application to the N6Cam, you must sign the binaries. To achieve this you’ll need to:

1. Create a “Binaries” folder on <ROOT>

2. Open a terminal on <ROOT> and run the signing command on the compiled binaries:

   1. FSBL:

      Code Block
      language bash
      STM32_SigningTool_CLI -bin Sources\STM32CubeIDE\FSBL\Release\Siana.N6Cam.BSP.FSBL.bin -nk -of 0x80000000 -t fsbl -o Binaries\Siana.N6Cam.BSP.FSBL.signed.

      hexStandalone: Standalone\Release

      bin -hv 2.3 Binaries\Siana.N6Cam.BSP.FSBL.signed.bin

   2. Standalone:

      Code Block
      language bash
      STM32_SigningTool_CLI -bin Sources\STM32CubeIDE\Standalone\Release\Siana.N6Cam.BSP.Standalone.bin -nk -of 0x80000000 -t fsbl -o Binaries\Siana.N6Cam.BSP.Standalone.signed.

      hex

...

1. 1. bin -hv 2.3 Binaries\Siana.N6Cam.BSP.Standalone.signed.bin

Loading binaries

With the N6Cam unpowered and STLink unplugged from your host machine.

1. Set the N6Cam switch to development mode

2. Plug the STDC14-STDC14 flat cable to connect the STLink and the N6Cam

3. Plug the N6Cam and the STLink to your host machine

4. Open the STM32CubeProgrammer (if closed):

   1. Configure the external loader:

      

      1. (1) Go to the “external “External loaders” tab

      2. (2) Search for STM32N6

      3. (3) Select the MX66UW1G45G loader

   2. Connect to the device:

      

      1. (1) Select ST“ST-Link LINK” from the dropdown menu

      2. (2) Configure the device as shown: Hot plug mode, with Software reset, for access port 1

      3. (3) ConnectClick “Connect”

   3. Flash Flashing the firmware:

      Image RemovedImage Added

      1. (1) Go to the “erase “Erasing & programming” Programming” tab

      2. (2) Browse for the images to be flashed, to be either:

      3. From script build: All are located in <ROOT>\RELEASE\SIANA.N6Cam.BSP-Binaries-<VERSION>\Binaries

         1. Model: SIANA.N6Cam.BSP-Standalone-<VERSION>_AI.Model_PeopleDetect.hex

         2. FSBL: SIANA.N6Cam.BSP-FSBL-<VERSION>.hex

         3. Standalone: SIANA.N6Cam.BSP-Standalone-<VERSION>.hex

      From IDE build:

      Model: <ROOT>\N6Cam.BSP

      binaries and (3) configure the start address as follows:

      1. FSBL:

         1. Image: <ROOT>\Binaries\Siana.N6Cam.BSP.FSBL.signed.bin

         2. Address: 0x70000000

      2. Standalone:

         1. Image: <ROOT>\Binaries\Siana.N6Cam.BSP.Standalone.signed.bin

         2. Address: 0x70080000

      4. (4) Click “Start Programming”

   4. Flashing the AI model:

      Image Added

      1. (1) Go to the “Erasing & Programming” tab

      2. (2) Browse for model binaries: <ROOT>\Sources\Model\network_data.hex
         

      3. FSBL: <ROOT>\N6Cam.BSP\STM32CubeIDE\FSBL\Release\Siana.N6Cam.BSP.FSBL.signed.hex

      Standalone: <ROOT>\N6Cam.BSP\STM32CubeIDE\Standalone\Release\Siana.N6Cam.BSP.Standalone.signed.hex

      Note: Since this is a hex file you don’t need to set the target address

      4. (3) Click “Start Programming”

5. Disconnect both the N6Cam and the STLink from the host machine

6. Set the N6Cam to operation mode

7. Connect the N6Cam to the host machine
