Jp4.5.1 jetson_nano boot from external usb SDD without sdcard

I upgraded my jetson_nano DEVKIT using sdkmanager tools, and now my jetpack version is jp4.5.1;

I follow the steps to copy kernel from sdcard to SSD;
then i remove the sdcard ,But nano can not bootup; here are the logs ;

I don’t know what does bootfromUSB do to your usb drive, but the uboot log says there is no usb storage device detected.

Maybe you can try different usb ssd or use external power supply to your SSD.
