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.
Contents
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 . ├── boot.cmd ├── boot.scr ├── config-4.4.143-61-rockchip-g1f77a85486f7 //copy from ubuntu ├── dtbs //.dtb file,we need rockpi-s-linux.dtb,copy from ubuntu │ └── 4.4.143-61-rockchip-g1f77a85486f7 │ └── rockchip │ ├── overlay //.dtbo files,copy from ubuntu │ │ ├── i2c1-hym8563.dtbo │ │ ├── README.rockchip-overlays │ │ ├── rk3308-console-on-uart0.dtbo . . . │ ├── rk3308-rock-pi-s.dtb . . . ├── extlinux //copy from ubuntu │ └── extlinux.conf ├── initrd.img-4.4.143-61-rockchip-g1f77a85486f7 //ramdisk,copy from ubuntu ├── pxelinux.cfg //this folder is important,you can make the folder by yourself │ └── 01-5e-50-a4-83-72-98 //named it by env ethaddr of uboot.i will introduce this file ├── System.map-4.4.143-61-rockchip-g1f77a85486f7 ├── uEnv.txt └── vmlinuz-4.4.143-61-rockchip-g1f77a85486f7 //this is a kernel image,copy from debian or build by yourself
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 label kernel-4.4.143-61-rockchip-g1f77a85486f7 kernel /vmlinuz-4.4.143-61-rockchip-g1f77a85486f7 //choose your kernel image initrd /initrd.img-4.4.143-61-rockchip-g1f77a85486f7 //choose your ramdisk devicetreedir /dtbs/4.4.143-61-rockchip-g1f77a85486f7 //choose your dtb folder append earlyprintk console=ttyFIQ0,1500000n8 rw init=/sbin/init rootfstype=ext4 rootwait root=UUID=f6864320-28f2-41de-a865-3c2fb8d0e670 //this is bootargs for kernel
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:
=>pxe get
