The following definitions that deal with the placement and management
of environment data (variable area); in general, we support the
following configurations:
Please note that the environment is read-only until the monitor
has been relocated to RAM and a RAM copy of the environment has been
-created; also, when using EEPROM you will have to use getenv_r()
+created; also, when using EEPROM you will have to use getenv_f()
until then to read environment variables.
The environment is protected by a CRC32 checksum. Before the monitor
interface is currently active. For example you
can do the following
- => setenv ethact FEC ETHERNET
- => ping 192.168.0.1 # traffic sent on FEC ETHERNET
- => setenv ethact SCC ETHERNET
- => ping 10.0.0.1 # traffic sent on SCC ETHERNET
+ => setenv ethact FEC
+ => ping 192.168.0.1 # traffic sent on FEC
+ => setenv ethact SCC
+ => ping 10.0.0.1 # traffic sent on SCC
ethrotate - When set to "no" U-Boot does not go through all
available network interfaces.
