When I set MAC addresses on the LS1021ATSN-PA board in U-Boot according to Open Industrial Linux User Guide:
This is the command:
\0x1b7\0x1b[r\0x1b[999;999H\0x1b[6nroot@ls1021atsn:~# setenv ethaddr 00:04:9f:ef:00:00
And the reply is:
-sh: setenv: not found
Why can't this command be found? What should I do?
