Hi, thank you so much for you answering! I solve the problem by reinstall the Orin nano image to SD card and set it up again, and then follow your answer in this blog:Orin Nano won't boot. "LT4Launcher attempting recovery boot",
Thank you very much!!!
But now I found that, every time when I open it, it will first hit LT4 launcher issue and winning with test keys, and then I will try to reboot again, after this second automatically reboot it will open normally. Is this correct? Or how could I solve this problem?
Thanks for your patient!!
