TFTP_DIRECTORY
refers to the directory to store
bootloader
,
ddr init
, and
u-
boot
files.
Step 6
Restart the tftp server by executing:
sudo systemctl restart tftpd-hpa
Step 7
Power on the VisionFive and wait until it enters the u-boot mode.
Step 8
Configure the environment variables by executing:
setenv ipaddr 192.168.120.200;setenv serverip 192.168.120.12
Generally, the default IP of a router is
192.168.120.1
. In this case, use the server
IP as the IP assigned by the DHCP server of the router and use the VisionFive IP as
. However, if your router IP is different (for example,
192.168.2.1
), make sure the server IP and VisionFive IP are in the same IP domain
).
Step 9
Check the connectivity by pinging the host PC from VisionFive:
Example Command:
ping 192.168.120.12
Result:
The following output indicates that the host PC and VisionFive has established com-
munication on the same network.
