the default boot order is sd->usb/nvme
make sure you only have 1 boot device at power on
yours might of kicked the bucket

i'm running on usb so i know it works

Hello.

Thanks for your answer.

It does not show anything on the screen when starting without boot or with boot device.

I tried connecting USB with boot written on it, and I put out the SD card that time, but still showing only black screen and blinking leds both green and red.
