Hi 

To flash the images to the emmc boot 0 partition using tftp ,please follow these steps:

STEP 1: On Host PC create the TFTP server's base directory

sudo mkdir /tftpboot
sudo chmod -R 777 /tftpboot
sudo chown -R nobody /tftpboot

STEP 2: Copy all the boot images to the tftp boot partition. For example, in j721e copy the below files:
tiboot3.bin,
sysfw.itb,

STEP 3 : Boot upto UBOOT using any boot mode(sd/dfu/tftp) ,halt at UBOOT and run below command:

=>setenv serverip $(serverip)
=>dhcp
=>mmc dev 0 1

=>tftp ${loadaddr} tiboot3.bin
=>mmc write ${loadaddr} 0x0 0x400
=>tftp ${loadaddr} tispl.bin
=>mmc write ${loadaddr} 0x400 0x1000
=>tftp ${loadaddr} u-boot.img
=>mmc write ${loadaddr} 0x1400 0x2000
=>tftp ${loadaddr} sysfw.itb
=>mmc write ${loadaddr} 0x3600 0x800
=>mmc partconf 0 1 1 1
=>mmc bootbus 0 2 0 0

STEP 4 : Change the boot switch  to emmc(boot 0) as below:

SW8[1:8]=1000_0000
