STM32N6570-DK AI demo not working

[ClosedBridge]

Hello,

I recently bought the newly released development kit STM32N6570-DK that includes a touch screen and a MIPI camera manufactured by ST. It comes preprogrammed with some nifty demos, including the AI demo which should show off the AI capabilities with a stream from the included camera. When I load the AI demo the screen freezes up, and I can see the backlight to the screen turn off.

Additionally I noticed there are some level shifters (TR1 on the camera module) on the PCB for the camera that either carry a clock or data line for MIPI. When I activate the demo the 3.3V line starts toggling at about 160MHz for about 2ms, and then stays low after that.

For reference, I am powering the dev kit off of a USB 3.0 port on my laptop.

Could you help me identify if this is a camera module, dev kit, power, or cable issue?

Thanks,

-Alex

Thanks.  That worked perfectly.

I was worried that I had damaged something.  For anyone else experiencing this, look at L03.  When connected to a USB-A on my laptop, it came up yellow and changed to red when I started the AI demo.  With power from a USB-C port on my laptop, it came up green and stayed green when the demo started.
