ROCK Pi 4 > Development > U-boot > 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 4 supports PXE boot and it's enabled by default. This page describe how to use PXE boot on ROCK Pi 4.
Contents
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 16.04LTS,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:
#:/data/tftp_server$ tree . ├── config-4.4.154-88-rockchip-00030-g90239a6 //copy from debian ├── dtbs //.dtb file,we need rockpi-4b-linux.dtb,copy from debian │ └── 4.4.154-88-rockchip-00030-g90239a6 │ └── rockchip │ ├── ficus-linux.dtb │ ├── px30-evb-ddr3-lvds-v10.dtb . . . │ └── rockpi-4b-linux.dtb ├── extlinux //copy from debian │ ├── extlinux.conf ├── hw_intfc.conf //copy from debian ├── initrd.img-4.4.154-88-rockchip-00030-g90239a6 //ramdisk,copy from debian ├── overlays //.dtbo files,copy from debian │ ├── at24c02.dtbo │ ├── console-on-ttyS2.dtbo │ ├── console-on-ttyS4.dtbo . . . │ ├── spi1-waveshare35c.dtbo │ └── two-color-led.dtbo ├── pxelinux.cfg //this folder is important,you can make the folder by yourself │ ├── 01-be-73-e6-4e-04-2b //named it by env ethaddr of uboot.i will introduce this file │ └── extlinux.conf └── vmlinuz-4.4.154-88-rockchip-00030-g90239a6 //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=be:73:e6:4e:04:2b
so i named my pxe configaration file 01-be-73-e6-4e-04-2b,or you can named it default
:/data/tftp_server/pxelinux.cfg$ cat 01-be-73-e6-4e-04-2b

initrd initrd.img-4.4.154-88-rockchip-00030-g90239a6 //choose your ramdisk
append earlycon=uart8250,mmio32,0xff1a0000 swiotlb=1 coherent_pool=1m earlyprintk console=ttyFIQ0,1500000n8 rw root=PARTUUID=b921b045-1d rootfstype=ext4 init=/sbin/init rootwait //this is bootargs for kernel
Rock Pi 4
we must install uboot on spi flash or emmc or microSD,this document is used spi flash,so please see spi-install to install uboot in spi flash
Step 1: Configure ip addr
enter uboot,and set some env:
=> setenv ipaddr xx.xx.xx.xx //set rockpi4 ip => setenv serverip xx.xx.xx.xx //set ip of tftp
Step 2: run pxe boot cammand
when you run bootcmd_pxe,uboot will get some boot files from your tftp server.as follows:
=>run bootcmd_pxe
