4. How to run the demo program:

4.1. Open the virtual machine downloaded in step 3, username xstrive, password 123456
The virtual machine has a built-in tftp server
Restart tftp server: sudo service tftpd-hpa restart

4.2 Flash the kernel and file system on the board
setenv serverip 192.168.0.75;setenv ipaddr 192.168.0.222;sa;

3）Flash the kernel 
mw.b 82000000 ff 400000;tftp 82000000 uImage_hi3520dv400;sf probe 0;sf erase 100000 400000;sf write 82000000 100000 400000
4) Flash the file system
mw.b 82000000 ff B00000;tftp 0x82000000 rootfs_hi3520dv400_64k.jffs2;sf probe 0;sf erase 500000 B00000;sf write 82000000 500000 B00000

5）Set boot parameters
    setenv bootargs 'mem=128M console=ttyAMA0,115200 root=/dev/mtdblock2 rootfstype=jffs2 rw mtdparts=hi_sfc:1M(boot),4M(kernel),11M(rootfs)';setenv bootcmd 'sf probe 0;sf read 0x82000000 0x100000 0x400000;bootm 0x82000000';sa;re

4.3 Plug the HDMI signal source into the board
4.4 Run the demo program

ifconfig eth0 192.168.0.136

cd /Hi3521DV100_SDK_V1.0.5.0/it6801_drv/it6801/ && ./hdmi&
cd ../../mpp/sample/venc

./sample_venc 0
#Select c, and you can see the recording in the virtual machine directory /home/xstrive/hisi/Hi3521DV100_SDK_V1.0.5.0/mpp/sample/venc/

4.5 Create your own file system
cd /home/xstrive/hisi/Hi3521DV100_SDK_V1.0.5.0/osdrv/pub
#Put the files you need into the rootfs folder
mkfs.jffs2 -d ./rootfs -l -e 0x10000 -o rootfs.jffs2
