I designed a PCB for an Nvidia Jetson Nano, but it cannot power up or start the system on it. Due to the dimensions of the board, it was not possible to place HDMI on it, therefore, only ethernet (the performance of which has not been proven) and USB were possible to communicate with Jetson. The schematic is identical to the supplied circuit board and corresponds to the datasheet.
At the moment I tried to change the value of the resistor going from POWER_EN to + 5V, but it didn’t help. Jetson consumes around 0.3A. Also voltage on MOD_SLEEP is 1,8V
The diagram is in the app, thanks in advance for your help

Was it boot into recovery mode? Would you please check the USB device available with USB cable connect to host PC?
When Jetson is connected to a PC, it is recognized as an unknown device. Also I leave FORCE_RECOVERY* pin fully disconnected
Is there debug UART port on your board? Do you have any log info got?
There is no update from you for a period, assuming this is not an issue any more.
Hence we are closing this topic. If need further support, please open a new one.
Could you see recovery device if power on the module with Force_recovery* pressed?
Did you check if the module is able to boot up on reference carrier board?
