I have been working in the arty z7, working to output HDMI video from a camera conencted by ethernet .
While the ehternet hardware, driver and code are fully functional. I have yet to make the hdmi function on the OS.
Currently, i have follow succesfully the following tutorial, that means that i have the hardware for HDMI in and out and can use through the provided Bare metal application.
Now, i have to move this functional hardware form a bare metal application to a OS application, for that i need some drivers to control the Axi Stream conected to the VDMA and to the HDMI output.
To be honest I dont even know where to start with this task, do any of you have any pointers, are there pre-developed drivers for this situation?.
Thanks for any information
PD: the current version of OS i am using is linaro, i dont think it changes anything but just in case.
