Thanks.

Burn the images on SD as below, but the board boot from eMMC.  So it
will boot from SD only eMMC has bad image or any jumper to make SD
boot?
$ ./tools/mkimage -n rk3399 -T rksd -d spl/u-boot-spl.bin idbspl.img
$ sudo dd if=idbspl.img of=/dev/sda seek=64
$ sudo dd if=u-boot.itb of=/dev/sda seek=16384
