    ROCK Pi S >  Development > PXE BOOT

PXE boot, Preboot eXecution Environment is a specification describes a standardized client-server environment that boots a software assembly, retrieved from a network. U-boot of ROCK Pi S supports PXE boot and it's enabled by default. This page describe how to use PXE boot on ROCK Pi S.

PC Server setting

this document is used tftp server to test pxe boot to ramdisk,next,we will instruct on installing and configuring the tftp server in ubuntu 18.04.5 LTS,and preparing some boot files.

Step 1: Install TFTP and TFTP server

 sudo apt-get install tftp-hpa tftpd-hpa

Step 2: Configure TFTP server

1.Create a folder,like this:

 mkdir /data/tftp_server

2.modify configuration file,like this:

 $ cat /etc/default/tftpd-hpa 
 # /etc/default/tftpd-hpa
 
 TFTP_USERNAME="tftp"
 TFTP_DIRECTORY="/data/tftp_server"
 TFTP_ADDRESS="0.0.0.0:69"
 TFTP_OPTIONS="-l -c -s"

Step 3: Restart tftp

 service tftpd-hpa restart

Step 4:Preparing boot file

copy all files from debian os boot partition,as follows:

 #:sudo scp -r rock@ip:/boot/* /data/tftp_server
 #:/data/tftp_server$ tree

Pxelinux.cfg

named pxe configaration file,run to uboot and print ethaddr:

 ...
   hclk_perilp1 100000 KHz                                                                                                                 
   pclk_perilp1 50000 KHz                                                                                                                  
 Net:   eth0: ethernet@fe300000                                                                                                            
 Hit key to stop autoboot('CTRL+C'):  0                                                                                                    
 => print ethaddr                                                                                                                          
 ethaddr=5e:50:a4:83:72:98

so i named my pxe configaration file 01-5e-50-a4-83-72-98,or you can named it default

 :/data/tftp_server/pxelinux.cfg$ cat 01-5e-50-a4-83-72-98

Rock Pi S

we must install uboot on microSD,this document is used microSD,so please see | microSD to install uboot in microSD

Step 1: Configure ip addr

enter uboot,and set some env:

 => setenv ipaddr xx.xx.xx.xx         //set rockpis ip
 => setenv serverip xx.xx.xx.xx        //set ip of tftp

Step 2: run pxe boot cammand

when you run pxe cammand,uboot will get some boot files from your tftp server.as follows:
