Prepare TFTP server

Make sure TFTP server is running and contains the uncompressed Ubuntu image file (in this example we will use ubuntu-whle-ls1046a-02-10-2021-3bbd6c2.img).

Configure network in U-Boot

Plug in an Ethernet cable to the ETH0 port and start the board. Use dhcp command at the U-Boot prompt to acquire the IP address. After that, set the IP address of the TFTP server using setenv serverip x.x.x.x command, as shown below:
