ROCK Pi 4 > Desarrollando > U-boot PXE
PXE boot, Preboot eXecution Environment es una especificación que describe un entorno estándar cliente servidor que inicia software ensamblado, desde una red. U-boot del ROCK Pi soporte boot PXE y está activo por defecto. Esta página describe como usar el boot PXE del ROCK Pi 4.
Contents
Configuración del Servidor
Este documento es usado por el servidor tftp para probar boot pxe en ramdisk, a continuación, instalamos y configuramos el servidor tftp con Ubuntu 16.04LTS, y preparamos algunos archivos de inicio.
Paso 1: Instalar TFTP y el servidor TFTP
sudo apt-get install tftp-hpa tftpd-hpa
Paso 2: Configurar el servidor TFTP
1.Crear una carpeta, así:
mkdir /data/tftp_server
2.Modifica el fichero de configuración, así:
$ 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"
Paso 3: Reiniciar tftp
service tftpd-hpa restart
Paso 4: Preparar el fichero de inicio
copiamos todos los archivos de debian en la partición boot, de esta forma:
#:/data/tftp_server$ tree . ├── config-4.4.154-88-rockchip-00030-g90239a6 //copia de debian ├── dtbs // el fichero .dtb, que necesitamos rockpi-4b-linux.dtb, copiar de debian │ └── 4.4.154-88-rockchip-00030-g90239a6 │ └── rockchip │ ├── ficus-linux.dtb │ ├── px30-evb-ddr3-lvds-v10.dtb . . . │ └── rockpi-4b-linux.dtb ├── extlinux //copia de debian │ ├── extlinux.conf ├── hw_intfc.conf //copia de debian ├── initrd.img-4.4.154-88-rockchip-00030-g90239a6 //ramdisk,copia de debian ├── overlays // ficheros .dtbo,copia de debian │ ├── at24c02.dtbo │ ├── console-on-ttyS2.dtbo │ ├── console-on-ttyS4.dtbo . . . │ ├── spi1-waveshare35c.dtbo │ └── two-color-led.dtbo ├── pxelinux.cfg // esta carpeta es importante, puedes crear la carpeta por ti mismo │ ├── 01-be-73-e6-4e-04-2b // llamándolo env ethaddr de uboot. yo introduciré este archivo │ └── extlinux.conf └── vmlinuz-4.4.154-88-rockchip-00030-g90239a6 // esta es una imagen del nucleo, copia de debian o compilalo tu mismo
Pxelinux.cfg
Fichero de configuración pxe, ejecutar uboot e imprimir 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
así llamé a mi fichero de configuración pxe 01-be-73-e6-4e-04-2b, o puedes nombrarlo por defecto
:/data/tftp_server/pxelinux.cfg$ cat 01-be-73-e6-4e-04-2b

initrd initrd.img-4.4.154-88-rockchip-00030-g90239a6 // escoge tu 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 // esto es bootargs para el nucleo
Rock Pi 4
debemos instalar uboot en flash spi o en emmc o microSD, este documento usa spi flash, así que mira spi-install para instalar uboot en spi flash
Paso 2: Configurar direccion ip
enter uboot,and set some env:
=> setenv ipaddr xx.xx.xx.xx //establecer la direccion ip rockpi4 => setenv serverip xx.xx.xx.xx //establecer la ip a tftp
Paso 3: ejecutar comando pxe boot
cuando ejecute el comando pxe, uboot obtendrá algunos ficheros de su servidor tftp, así:
