But it seems the previous existing folder located into ./rkbin/firmware/rockchip is no longer exists in that new version. This folder included the file "dptx.bin" (Type-C DisplayPort Driver).
So, when I try to compile the master code including this new change, I get an error because it's missing. Now I changed manually the builder to avoid taking this missing file, but I wonder if this is really needed to get the system working properly.
Jack Ma, did you remove it for some reason?
