There are Dusun SDKs with all sources available but what they are using are ancient 2017.09 u-boot version which are forked in mirrors rooting to a rockchip github tree. Now I am fighting with a Dusun SDK using a rather vanilla 2022 u-boot which is not the same, I just managed to get a working SDRAM setup. Now reading MMC gives mmc block read error probably yielding to DT setup issues. Then we will investigate what has to be done among the common stuff to put this into barebox. Kind Regards Konstantin
