=================================================
For Rock64 rk3328 board the following three parts are required:
-TPL, SPL, and the u-boot image tree blob. While u-boot-spl.bin and
-u-boot.itb are to be compiled as usual, TPL is currently not
-implemented in u-boot, so you need to pick one from rkbin:
-
- - Get the rkbin
-
- => git clone https://github.com/rockchip-linux/rkbin.git
+TPL, SPL, and the u-boot image tree blob.
- Create TPL/SPL image
- => tools/mkimage -n rk3328 -T rksd -d rkbin/bin/rk33/rk3328_ddr_333MHz_v1.16.bin idbloader.img
+ => tools/mkimage -n rk3328 -T rksd -d tpl/u-boot-tpl.bin idbloader.img
=> cat spl/u-boot-spl.bin >> idbloader.img
- Write TPL/SPL image at 64 sector
