When I power up the J90, the fan run at maximum speed and nothing happens

Hi !

I have buy a J90 Motherboard for the Jetson TX2. When I power up the J90 with 12V 10A, the fan run at maximum speed and the power button has no effect.

Nothing is connected to the motherboard except the fan.

Is someone have an idea of the problem ?

Thanks :)

Are you sure there is a problem?
Maybe the fan is just enabled by the board being powered (unlike Jetson dev board using pwm), unrelated to power button.
I have no experience with this board, but connecting a serial console (framing 115200 8N1) may confirm if there is a problem, and if yes where in the boot process it happens.

Sorry for the post. I was actually working. :/
