hello edwardlu,

you need to create an SMD image by using nv_smd_generator,
after that, please execute nv_update_engine on the target to enable/disable redundancy feature, and redundancy settings.
here’s developer guide for your reference, Bootloader Update and Redundancy.
thanks

Thanks JerryChang.
And so,this suppose to be a condition,I must have a 64GB size EMMC?
Because the image is about 32GB.
