### ETH Burn

Eth is burned under uboot, so you need to make sure that uboot has been burned.
Note: when burning through the network, the development board needs to connect the network cable, and the development board and PC end are in the same network segment.

• Download and unzip tools/tftpd32.rar and enter the unzip directory. Double click to run ftpd32.exe to open the TFTP server

• The board enters into uboot and sets two environment variables IPADDR and ServerIP to ensure that the board and the computer can communicate

# setenv ipaddr 192.168.1.112
# setenv serverip 192.168.1.166
# saveenv


• Execute ESTAR to update the system
