Hi,

I've built the rk3288 and puts the Rockchip header and SPL image first and then places the U-Boot image at block 256 (i.e. 128KB from the start of the SD card) as

# ./tools/mkimage -n rk3288 -T rksd -d spl/u-boot-spl-dtb.bin SPL # dd if=SPL of=/dev/mmcblk0 seek=64 # dd if=u-boot-dtb.img of=/dev/mmcblk0 seek=256

Observed an issue of ROM not returning back and load u-boot, any help?

Log: ----- spl:printf uart enabled in board_init_f

spl:init dram

U-Boot SPL 2017.07-00314-gd56b4b1-dirty (Jul 25 2017 - 15:45:49) Returning to boot ROM...

thanks!
