deployment model zoo

[emmanuel_]

Dear all,

I am currently deploying the image_classification application.

So, from stm32ai-modelzoo-services (in my case, it is in the directory stm32ai-modelzoo-services4), I am using the following command with my configuration file:

python .\stm32ai_main.py --config-path . --config-name .\user_deployment_n6_config.yaml

I added some code in /common/stm32ai_local/build.py to help diagnose the programming of the STM32N6570-DK board.

The programming process seems to complete correctly, but when I restart the kit (with BOOT0 and BOOT1 set to the left), the screen remains black.

However, if I launch STM32CubeIDE, import my application, perform a build, and then a Run As, the programming works correctly and the application runs perfectly.

I believe the original goal is, of course, to be able to program and run my application directly using the script:

python .\stm32ai_main.py --config-path . --config-name .\user_deployment_n6_config.yaml

Please find attached the execution log of the script.

Many thanks in advance for your help.

Hi,

I keep trying to make progress…

https://github.com/STMicroelectronics/STM32N6-GettingStarted-ObjectDetection

in the documentation : 

On STM32N6570-DK:

export DKEL="<STM32CubeProgrammer_N6 Install Folder>/bin/ExternalLoader/MX66UW1G45G_STM32N6570-DK.stldr"

# First Stage Boot Loader
STM32_Programmer_CLI -c port=SWD mode=HOTPLUG -el $DKEL -hardRst -w FSBL/ai_fsbl.hex

# Adjust build path as needed
STM32_Programmer_CLI -c port=SWD mode=HOTPLUG -el $DKEL -hardRst -w build/Application/STM32N6570-DK/Project_sign.bin 0x70100000

# Network parameters
STM32_Programmer_CLI -c port=SWD mode=HOTPLUG -el $DKEL -hardRst -w Model/STM32N6570-DK/network_data.hex

I write a code ( test_bat.bat , please rename test_bat.txt to test_bat.bat )  to program the kit :

 but without a succes....

cheers
