Verilog FPGA Program 2 (MicroBlaze, Arty A7-35T)

FPGA MicroBlaze is a daunting task to study!
You can get a lot of fun with this lecture 💪

Lecture Topics 📖

There are many difficulties in dealing with FPGA. In order to implement FPGA, you need to have not only HW knowledge, but also a lot of understanding of the tools and Verilog syntax used. Porting and using MCU requires even deeper knowledge. Xilinx provides a lot of documentation on FPGA, but when you look at the documentation, there are too many cases where you are referred to other documents. Therefore, it is very difficult for anyone other than experienced developers to read and understand the documentation provided by Xilinx.

This lecture explains in detail how to port and use MicroBlaze on Xilinx FPGAs , starting from the process of installing the tools. How to port and use MicroBlaze , We'll walk you through implementing the interface between your user logic and the MCU in detail. Take your career to the next level with skills using MicorBlaze in FPGAs!

If there is anything you do not understand in the lecture, please post a question through the Inflearn community or the cafe I run and I will answer it.

Section 1. HW Configuration

Section 2. Vitis 2022.1 Installation Process

• Vitis is a very heavy tool. I will explain what you need to be careful about when installing it and how to install it without conflicting with your current Vivado.

Section 3. Print “Hello world” to the screen with MicroBlaze

• This section aims to give you an overview of the flow.

Section 4. Peripheral of MicoBlaze

• We will explain the GPIO, Timer, Uart, and Interrupt that are mainly used. Since the peripherals provided by MicroBlaze are similar, if you learn the contents of the lecture, you can easily use other peripherals.

Section 5. Knowledge that can be applied in practice

• Most of the material ends with dealing with the Peripheral. However, the purpose of using MicroBlaze in FPGA is to control the user-designed logic through MicroBlaze. Ultimately, it is to control the user-designed logic through the UI(User Interface).
• In this lecture, we added 4 PWM modules to configure User Logic. We configured Register Map to control User Logic, and controlled User Logic through MicroBlaze and UI. We explained and implemented all of these processes and showed the results.
• The content described in this section can be applied directly to practice. All you have to do is add User Logic and Register Map, and you can use all other processes as implemented.

Section 6. lwIP Echo Server

• This is about implementing an Echo Server using lwIP. Implement a DDR Controller to use Cache (Instruction Cache, Data Cache) in MicroBlaze.

Section 7. Using lwIP

• This explains the process of adding User Logic to TCP/IP communication using lwIP. This explains the process of sending a command using TCP/IP from a PC, receiving the command via lwIP, and controlling the LED of the board in User Logic. Through this, the interface between lwIP and User Logic is implemented and the results are confirmed.

Section 8. TCP/IP Implementation Using W5500 Module

• This is the content added in v1.4. It is about implementing TCP/IP using wiznet's w5500 module. It implements data transmission and reception by connecting to a PC and a network. If you apply this, you will be able to apply it in various fields that utilize TCP/IP.

Section 9. Block Memory Interface - 1

• Added in v1.5. Implements the Block Memory Interface provided by default in Block Design.

Section 10. Block Memory Interface - 2

• This is what was added in v1.5. Block Memory is added to User Logic to implement Block Memory Interface. By applying this, User Register Map is implemented, and an example of controlling frequency and duty of PWM is implemented.

History

I have been working as a developer for over 20 years in large and small companies and currently run a small business. I have developed an ISP(Image Signal Processing) ASIC for CCTV and many products using FPGA such as OLED inspection equipment and DAQ(Data Acquisition System). In addition to FPGA, I have a lot of experience in FW development (STM32, PIC32, AVR, ATMEGA, etc.), circuit design, Windows Program, etc.
