Hi everyone,
I am using the Digilent Embedded Linux on Zedboard:
https://digilentinc.com/Support/Support.cfm?ProdCat=EMBEDDED-LINUX&DocType=
I have written a DMA Module for the FPGA, which transferes Videodata into the DDR. Also I wrote a kernel-module to control my DMA module and to allocate the memoryspace in the DDR where my Modul is allowed to write to. When enough videodata is transferred, my hardware-module sends an interrupt to the GIC and my kernel-module starts an ISR.
So far everything works fine, the Data is written into main memory without killing the system and the ISR gets executed.
Now I need expand this ISR to display that videodata somehow on the Monitor at the HDMI port, besides the standard output. For the beginning it would also be good enough to display only my videodata instead of the normal output.
The Problem is, I am not very expirienced at the software site and I have no idea what I could try, where to start or where I can get usefull information.
Does anyone of you have an idea how I could do that or where I can find information about such stuff?
Thanks in advance
Tobias
