Hello, all!
I connected not right another board in gpio. My Nano stopped booting. Serial Console don’t have any output. Is there anything I can try to do to restore it?
Jetson Nano 4Gb, Adafruit DC and Stepper Motor HAT for Raspberry Pi.
Green led is sgining, 5V and 3.3V voltage is in the gpio, UART-port is open.
Is there any way to check what exactly went wrong?

hello HerrAskin,

please remove all add-on devices for verification,
you may also check Jetson Nano - UART - JetsonHacks to setup serial console and gather booloader messages for reference,
thanks

I didn’t put it precisely enough. Of course, I immediately disabled the board Adafruit. And I did everything as per the instructions “Jetson Nano - UART - JetsonHacks”. The serial console shows nothing (((

hello HerrAskin,

please refer to developer guide, To determine whether the developer kit is in Force Recovery mode.
please check whether you’re able to detect the board with $ lsusb commands,
thanks

I set jumper on contacts FRC J40 and shortly RST. Then unplug jumpers.
But nothing has changed: $lsusb

hello HerrAskin,

you’re able to put the developer kit into Force Recovery Mode if they are connected when it is powered on;
so, if you’re disable auto power-on, you should have BUTTON_PWR_ON for the 1st time boot-up.
please check whether you’re able to enable the board. thanks

Hello JerryChang!
I put a jumper across Pin 7 and 8 J40. Auto power_on disabled. Then i apply the voltage 5V and remove jumper. Вridging 1 and 2 leads to nothing. The LED does not light up. I am forced to jump again at the same time 3 and 4 (Force Recovery), 7 and 8 (Auto power_on). But the output of lsusb is not changed.
Thanks.
