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
