I am completely new with seL4, embedded systems as well as the fpga world. I am working on installing seL4 on Zynq fpga and use it. I have successfully able to boot up a "hello world" application using uboot(sd card bootup) on the zynq device. However, I have no clue as in how to setup communication between the sel4 logic and the PL(fpga fabric). If I am correct some sort of device driver has to be written or is there anything that is inbuilt or someone else who has worked on a similar project. Any guidance in this regard will be utmost helpful.

Thanks a ton!
