Firmware for C019 24-bit ADC

Building

make manages the multiple stages of building the FPGA bitstream, Linux kernel, Linux drivers, and the final Debian based image. Refer to the Makefile's header for more information on how to build the project.

Directory structure

• constraints: Vivado xdc constraint files, e.g. pin definitions
• dts: Device tree sources, like the device tree overlay for the DMA driver
• library: Verilog/SystemVerilog IPs and vendor code
• linux: Patches for the Linux kernel, and the Linux kernel configuration
  • linux/dma: Sources for the DMADC Linux driver that manages the DMA
• projects: Source files for creating the Vivado projects (mostly in TCL)
• scripts: Scripts used to create the project, or build the image
• config.vlt: Configuration file for Verilator
• Makefile: Main entry point for make

Vivado Projects

The projects are build using AMD Vivado™ 2024.2 release. The block designs can be build using make:

make PROJECT=adc project

The projects are defined in tcl files and can also be created without make:

vivado -source scripts/project.tcl -tclargs adc xc7z010clg400-1 /build/projects/adc
