How to add HDMI support to a console-based Linux on the DE10 nano?

Question

It is possible to build an updated Linux Kernel for the DE10 nano following any of the following guides

https://bitlog.it/hardware/building-embedded-linux-for-the-terasic-de10-nano-and-other-cyclone-v-soc-fpgas/

or

https://www.digikey.com/eewiki/display/linuxonarm/DE10-Nano+Kit

However, you end up with a pure console-based Linux with no HDMI support. My question is, how do you activate the HDMI output? When building the Kernel a don't see any HDMI driver/module for the Kernel to load. Or is it done after the roots file system is created? How?

Thanks,

Manuel

Hi Manuel,

Short answer to your question is YES but HDMI support is not something that comes default in the reference design. This is something that you need to build your self.

HDMI is just another custom IP that you can follow in guideline to modify the golden reference design (GHRD) to add in HDMI design and it's respective Linux driver.

Your 2nd question is more on HDMI IP operation usage. You can refer to below HDMI user guide and its example design to learn more about Intel HDMI IP.
