I tried to rescue my Jetson Nano B01 by reflashing the bootloader. But I failed. Here is the debug information.
My Jetson Nano cannot boot up and output the following debug error.

I reckon this could be because of the corrupted bootloader and then try to reflash the bootloader using the SDKManager.
However, I get the following error message and cannot complete the bootloader flashing
