Running IIO Oscilloscope on a Custom ZynqBC Board
Adapted the Analog Devices IIO Oscilloscope software flow from a ZedBoard PetaLinux reference build and brought it up on a custom ZynqBC board with board-specific device tree changes.
Overview
Porting a known ZedBoard IIO flow to custom Zynq hardware.
The work involved using the PetaLinux build flow for the ZedBoard as the starting point, then adapting the Linux hardware description for the custom ZynqBC board so the target could expose IIO devices and connect to the Analog Devices IIO Oscilloscope application.
Device tree configuration
Updated the Linux device tree to describe board-specific peripherals, IIO nodes, and hardware connections.
Oscilloscope validation
Verified the target from the IIO Oscilloscope UI, including device selection and waveform transmission states.
Bring-Up Flow
From reference board assumptions to a working custom-board Linux target.
Start from the ZedBoard reference
Used the known ZedBoard PetaLinux build as the baseline for the Analog Devices IIO Oscilloscope workflow.
Map the flow to ZynqBC hardware
Adjusted the board setup for the custom ZynqBC platform instead of relying on ZedBoard hardware assumptions.
Configure device tree support
Updated device tree configuration so Linux could initialize the expected IIO-capable devices and board interfaces.
Validate from IIO Oscilloscope
Connected the Analog Devices IIO Oscilloscope application to the target and checked device selection and waveform behavior.
Evidence

Outcome
A custom ZynqBC board running the Analog Devices IIO workflow.
The project demonstrates PetaLinux board adaptation, device tree configuration, and Linux IIO validation on custom Zynq hardware, using the ZedBoard flow as a reference and proving the result through IIO Oscilloscope screenshots.
