I am trying to flash my AGX Orin 32GB development kit with sdkmanager 1.9.3. My host machine is ubuntu20.04 (not vm). The version I am trying to flash is 5.1.2.
I met this problem. But I have manually set the board to recovery mode ,by pressing and hold bottom 2, then press bottom 3 and hold, then release 3 then 2.
