[SOC] the first project of SOC Hello World

I. 1 Linux System environment construction

① Let's skip making system images , Use the card reader to SD Plug the card into the computer , First format the memory card , Then open the burning tool Win32Disklmager

② Find the path of our image file and import

And then click write Just wait for it to finish
③ Find the golden project prj In the catalog qpf file , Double-click to open

Then click compile , Wait for the compilation to complete
④ Find the output directory of the gold project , Running the script file will compile the generated sof Document conversion rbf file

Then replace the burned SD File with the same name in the card

⑤ Find generate_hps_qsys_header.sh file

⑥ open Intel FPGA Embedded Command Shell, Do the following

⑦ And then it generates soc_system.dtb file , Replace this file SD File with the same name in the card

thus , The environment is set up

II. Software design

stay ntel FPGA Embedded Command Shell The input eclipse& Command to open this software

Then select the new directory under the corresponding gold project app

Select new→C project

Set the name yourself , Other configurations are as follows , The final choice finish

Under the newly built project new →Source File Create a new file

Write the following code

Right click in the blank and select properties

Then configure as follows

The gold project hps_0.h Copy to the project directory

Finally, select compile

A binary file is generated

Third, configure the development board IP

Enter the setting development board /etc/ssh/ Under the table of contents , find sshd_config file
Use vi Command to open , Will be the first 44 The line is modified as follows

Then use the following command to modify IP

ifconfig eth0 10.2.0.14

And then restart the device

Set static IP
Use the following command to open interfaces file

vi /etc/network/interfaces

Modify the document as follows ：

auto eth0 
iface eth0 inet static 
address 10.2.0.14 
netmask 255.255.255.0 
gateway 10.2.0.1 
dns-nameserve 114.114.114.114

restart , see IP,IP The address is the above setting address , success .

IV SSH visit Linux

stay eclipse Middle configuration SSH

Right click new link

Then enter your development board IP

Enter the user name and password of the development board , Successful connection
Copy and paste the binary file generated by the previous compilation into opt Under the folder

Right click opt choice Launch Terminal, Input at the console chmod 777 hello_world Modify file properties , Usage language
sentence ./hello_world Execute the document .
