To use SNTP support, add a define CFG_CMD_SNTP to CONFIG_COMMANDS in
|
||
|
|
the configuration file of the board.
|
||
|
|
|
||
|
|
The "sntp" command gets network time from NTP time server and
|
||
|
|
syncronize RTC of the board. This command needs the command line
|
||
|
|
parameter of server's IP address or environment variable
|
||
|
|
"ntpserverip". The network time is sent as UTC. So if you want to
|
||
|
|
set local time to RTC, set the offset in second from UTC to the
|
||
|
|
enviroment variable "time offset".
|
||
|
|
|
||
|
|
If the DHCP server provides time server's IP or time offset, you
|
||
|
|
don't need to set the above environment variables yourself.
|
||
|
|
|
||
|
|
Current limitations of SNTP support:
|
||
|
|
1. The roundtrip time is ignored.
|
||
|
|
2. Only the 1st NTP server IP, in the option ntp-servers of DHCP, will
|
||
|
|
be used.
