Can I only to flash the kernel partition instead of the whole system via SD to eMMC flashing? If it can, how to? Thanks.

Use the parted command to get the partition numbers for the kernel and resource, then use the dd command to write resource.img and kernel.img:

$ sudo apt install parted $ sudo parted /dev/mmcblk0 print Model: SD SR32G (sd/mmc) Disk /dev/mmcblk0: 31.9GB Sector size (logical/physical): 512B/512B Partition Table: gpt Disk Flags:
