Requirements

Development Hardware

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

1 x STLink-V3 programmer
2 x STLink-V3MINIE programmer

Note:

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

Development Software

#	Name (+Link)	Version	Notes
1	STM32CubeIDE	1.17.0
2	STM32CubeN6	1.0.0	CubeIDE extension package
3	STM32CubeProg	2.18.0	Required for firmware signing

Note:

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

Code source

The following steps assume you have a copy of the N6Cam BSP sources release, which contents should look as follows:

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

Compiling the demo

Follow these steps to compile:

Open STM32CubeIDE
Go to File > Import...:
1. (1) Select General > Existing Projects into Workspace
2. (2) Click Next.
Find and import the projects:
1. (1) Click Select root directory
2. (2) Browse for the sources <ROOT> folder
3. (3) Select all projects (FSBL, and Standalone)
4. (4) Click Finish
Once loaded, your project should look like this:
Build both FSBL and Standalone using the “Release” profile
The generated binaries can be located at:
1. FSBL: <ROOT>\Sources\STM32CubeIDE\FSBL\Release\Siana.N6Cam.BSP.FSBL.hex
2. Standalone: <ROOT>\Sources\STM32CubeIDE\Standalone\Release\Siana.N6Cam.BSP.Standalone.hex

Loading & running the demo

Signing binaries

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

Create a “Binaries” folder on <ROOT>

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

FSBL:

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

Standalone:

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

Loading binaries

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

Set the N6Cam switch to development mode
Plug the STDC14-STDC14 flat cable to connect the STLink and the N6Cam
Plug the N6Cam and the STLink to your host machine
Open the STM32CubeProgrammer (if closed):
1. Configure the external loader:
  1. (1) Go to the “External loaders” tab
  2. (2) Search for STM32N6
  3. (3) Select the MX66UW1G45G loader
2. Connect to the device:
  1. (1) Select “ST-LINK” from the dropdown menu
  2. (2) Configure the device as shown: Hot plug mode, with Software reset, for access port 1
  3. (3) Click “Connect”
3. Flashing the firmware:
  1. (1) Go to the “Erasing & Programming” tab
  2. (2) Browse for the 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
  3. (4) Click “Start Programming”
4. Flashing the AI model:
  1. (1) Go to the “Erasing & Programming” tab
  2. (2) Browse for model binaries: <ROOT>\Sources\Model\network_data.hex
    Note: Since this is a hex file you don’t need to set the target address
  3. (3) Click “Start Programming”
Disconnect both the N6Cam and the STLink from the host machine
Set the N6Cam to operation mode
