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
Set the N6Cam to operation mode
