And there is one thing which I can't understand. Currently, u-boot based TPL/SPL located at 0x40 sector for rk3328. Why SPL u-boot loader can't read u-boot.itb from the filesystem? As far as I understand there is no "return to bootrom" step after SPL. So there should be no reason to find u-boot.itb at specific place at SD card.
