Yushenle's learning record: the first project of SOC FPGA -hello world

---

One 、Soc Environment configuration

1. Image burning

1） format TF card ：

First the TF card format For a volume

2） Using tools ： Win32DiskImager

Will be prepared in advance linux Simple image burn TF In the memory card

3） Start and use serial port debugging

1、 First, connect the serial port connection , Then turn on the computer Device manager .
as follows ：

Generally, it can be in port Found at , If in Other equipment Found in （ Usually with yellow exclamation point ） It means there is a problem with the drive , Update can .
2、 Use MobaXterm Connecting boards
Session Set as follows ：

3、 Press... On the board after the connection is completed RST Key , You can see the loading as follows ：

4、 Just log in as a user

Here we are SoC Of linux The environment has been set up .

Two 、Soc The golden project

1. Introduction to gold project

What is? Soc What about the golden project , In fact, it is done for a specific board Formwork works , Relevant Peripherals and HPS Etc. are configured in the project , Pin Also bind the completed project accordingly .

2. The benefits of using gold Engineering

Use the golden project , It can greatly reduce the burden of novice developers SoC Difficulty of project establishment , There is no need to write related top-level files , Developers only need to work in the golden project , On demand Discard or add the peripherals or interfaces you want .

3、 ... and 、Soc And hello world

1.SSH To configure

Get into ssh The configuration directory

cd /etc/ssh/

To configure ssh Set up

vi sshd_config

Will be the first 44 The row is configured as PermitRootLogin yes
So far SSH Configuration complete

2. The network configuration

To configure Soc Board static address

Enter the network configuration folder

cd /etc/network

modify interfacces The configuration file

vi interfaces

as follows ：

Here, the address of the board can be configured arbitrarily
After the configuration is completed, you can use the restart command to restart the board

reboot

After the restart is completed, enter

ifconfig

Check if the configuration is successful

You can see that the configuration is complete

Configure computer network address

Modify network settings

The address here can also be configured at will , But the main thing is Need to be on a network among .
This is related to the network Network configuration completed

3. Software coding

Code writing

Open up Quartus Directory embedded/ds-5/bin Medium eclipse

In the previous gold project app Folder Store software projects

On the eclipse New China C project

Add source files to the project hello_world.c
Write code

#include<stdio.h>
int main(){
    
	while(1)
	{
    
		printf("Hello World\n");
		//sleep(1);
	}
}

Environment configuration

The files to be configured are as follows ：

hps_0.h

Put hps_0.h Just copy it into the project

rest include To configure

Project — Properties

Select settings select C++ routine , Click the right side. add Add the path as shown in the figure

4. Code compilation and running

Compile code

After compilation, the following will appear Binary

If an error is reported , Note that after the code is written Pay attention to saving the file ,eclipse Code will not be saved automatically

function

Use eclipse Remote SSH Connect to the board

Open the window shown above

choice Remote System Explorer

Note that the address in the red box is Board configuration ip Address ,eclipse visit linux, The host to linux.
Input Login username and password that will do
Then the binary file generated by the previous compilation hello_world Copied to the

Root directory opt Under the document
Open the terminal in this directory

chmod +x hello_world

Modify the executable permissions of the file

./hello_world

Can run
