Hi, good job, learning is forever more better than reusing without understanding.
Thank for link to prebuilt modules, I take an eye to what can save time, anyway in your project cannot be of help, that is an SRAM and is too slow for video access, an SDram DDR is better and cost much less than static.
I see you pointed to rocket board example, that help a lot building compilers chain but also has prebuilt drivers, what happen if you load that image on your board? I suppose you need adapt fabric and all I/O on QSYS to match DE Nano hardware too.
Tomorrow if I get some spare time I check on resources of arrow board compared to DE0 nano soc
What you can see on VGA screen? If you booted system, are you able to allocate a video buffer in the user memory then initialise DMA registers to display it?
Regards

The arrow haves ddr3 mem in both hps and fpga fabric sides, i think that surely the video block uses the fpga ddr3 memory.
These example is useful to explore the kernel files and see how it works !!
I designed a expansion board (or cape) that fits perfectly with the nano soc, it includes an adv7123 video dac a wolfson audio codec but i will redesign it for adding a little ddr too(for the fpga side)
