Tool/software:
Hi,
I am developing an AM625x board.
I need documentation on how to program the Display subsystem for use with HDMI.
Unfortunately, the documentation in TRM just gives information on what the interface is and its features and functionalities. There is NO information on how to program it, detailed register description, how to configure DMA to interface with it, etc., and lots of other information.
I have had similar problems with CPSW, but somehow I managed to get it working because there existed an example that took me an eternity to reverse engineer because of similarly poor documentation. You can understand my pain in this thread: https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1230751/sk-am64-how-to-use-dma-for-cpsw-using-bare-metal
I presume the DSS works with Linux, and it has its own DSS drivers. Someone at TI should have written drivers for it and fundamentally would have done what I want to do. So someone should know how it works?
I cannot use Linux because of application constraints having multiple reasons, which I cannot list here, or it will make this post too long.
Would someone be kind enough to share with me some code or literature that I can read to program the DSS? I promise to be a good samaritan and share my knowledge, like the previous time, if I ever get it working :)
Thanks
