Spyros-Papanastasiou-667 / Z-turn-Board-V2-Diary

A newbie's diary on Zynq 🌌

Zynq @ Z-turn-Board-V2-Diary

Z-turn is a [cheap] chinese board featuring a Zynq processor. (Overview:pdf).

(Zynqs incorporate both a PL and a PS unit).
(My board has Zynq7020 with a dual core Arm & 80K logic cells).
I'll try to keep this repo "Beginner Friendly".. (This is NOT a tutorial: Corrections on each, next, chapter 😏).
I prefer a top-down approach.
