Install OS to SoM + Carrier Board

Hi all

Is there anybody know how to install the OS to the carrier board from Leopard Imaging. Now I have both the carrier board plus the SoM module, after power on nothing happens, it must be needed to install the OS to somewhere to boot the system, but seems no detailed info, is there anybody has experience on this ? Thank you very much.


Just a tip.

Some SoM chips are already working in RECOVERY mode after leaving from factory, means once power on, connect the carrier board with micro USB port, the system just detects the SoM system in REC mode, then just flash the L4T, that’s it.
