Good Evening,
I am trying to get TPL/SPL working on the rk3328-firefly ddr4 4gb board. I've pulled the ddr4 dtsi from the rockchip u-boot repository [0].
Unfortunately I cannot get the ddr4 to detect correctly.
Yes, the ddr4 support for rk3328 is missing now, we will update it some time later.
Thanks,

With the u-boot tpl, I get the following: U-Boot TPL 2020.01-rc3-00072-g1a1bea82b2-dirty (Dec 04 2019 - 08:33:54) data training error row errordata training error DDR4, 333MHz BW=16 Col=10 Bk=4 BG=2 CS0 Row=17 CS=1 Die BW=16 Size=2048MB
With the rk3328_ddr_333MHz_v1.16.bin, I get the following: DDR version 1.16 20190528 ID:0x805 N In DDR4 333MHz Bus Width=32 Col=10 Bank=4 Bank Group=2 Row=16/16 CS=2 Die Bus-Width=16 Size=4096MB ddrconfig:19 OUT
