The minimum system can only be operated through hyperterminal and there is no screen display.

Use tools: HyperTerminal, fastboot

Communication: serial port RS232

Operating environment: bootloader is completed after boot, but before the file system is mounted. (abort file system mount through HyperTerminal after boot)

Operation permission: root

Procedure:

1. Format (in order)

Fdisk-c 0 [partition command partition serial number: 0 (this command will empty emmc)]

Fatformat mmc 0:1 [formatted in "FAT" format, object: mmc, partition serial number 0 first partition]

Ext3format mmc 0:2 [formatted in "ext3" format, object: mmc, partition serial number 0 second partition]

Ext3format mmc 0:3 [formatted in "ext3" format, object: mmc, partition serial number 0 third partition]

Ext3format mmc 0:4 [formatted in "ext3" format, object: mmc, partition serial number 0 fourth partition]

Fastboot [say hello and get the hardware ready, and then start using fastboot]

As for why it is divided in this way, I don't understand it for the time being. The tutorial says you'll understand it later.

two。 Burn and write three big pieces

These three pieces are: uboot, kernel and file system.

Communication: USB OTG

Note: burning is implemented in the cmd console under the folder where the fastboot is located, not a serial hyperterminal. Copy all the files you want to burn into the fastboot folder.

Fastboot.exe flash bootloader u-boot-iTOP-4412.bin [flash: execute burn bootloader: burn write type u-boot-iTOP-4412.bin: burn write object]

Fastboot.exe flash kernel zImage [this command is used to burn the kernel (kernel)]

Fastboot.exe flash ramdisk ramdisk-uboot.img [ramdisk belongs to the file system]

Fastboot.exe flash system system.img [system obviously the body of the file system]

Fastboot-w [clear user space]

Fastboot reboot [restart]
