Jetson Nano can not boot after swap files zram

I followed this Install OpenCV on Jetson Nano - Q-engineering (
to install OpenCV. I installed dphys-swapfile and increased the size as 4096. Howerver after I reboot, Jetson nano could not reboot and I could not SSH. Someone please help me. Thank you so much in advance.


What do you mean Nano cannot reboot?
Does it get stuck in the booting stage?


Yes, I reboot and it get stuck, nothing on the screen. I could see the LED on board is on but nothing happened. I tried to connect through SSH via micro usb port on board but i did not work, no reply

I’'ve disconnected 02 CSI cameras and now it can reboot. I’ve removed dphys-swapfiles and it can reboot normally. Thank you very much for your help!
