kernel boot from SD card very slow

the image i use is compiled through yocto, a wic file, contains uboot, kernel image and rootfs:

but I skipped the uboot, and jump to kernel directly, in addition, I didn't use the kernel image in the wic, I repace it with my own kernel image.

# IMAGE_NAME: core-image-minimal-rockchip-rk3568-evb-20220622120153.rootfs.wic
 FIRMWARE_VER: 1.0
TYPE: GPT
CMDLINE: mtdparts=rk29xxnand:0x00002000@0x00004000(uboot),0x0000a508@0x00006000(boot),-@0x00014000(rootfs:grow)
uuid: rootfs=614e0000-0000-4b53-8000-1d28000054a9

I write the whole wic image to SD card sector 0, then I overwrite sector 0x6000 in order to run my kernel image, my kernel image only 12M.

then I read out the kernel image from sector 0x6000 to DDR, and start boot.

after run the init process, it takes almost 40 mins to finish.
