For some variables, for example "ipaddr", when I try to change them using "setenv" it does not update the current "ipaddr" variable in RAM it creates a new one and append it to the end of the variable list. As a result I end up having two "ipaddr" variables in RAM, one with the original value and one with the new value at the end of the list. If I try to set the variable a second time it deletes the first instance (the original) and adds the second new one to the end of the variable list.
This may be a little confusing so here is an abbreviated example. The '.....' represent the rest of the variables in the list.
Original list of variables --------------------- ....... ipaddr=10.0.5.2 ....... ---------------------
=>setenv ipaddr 10.0.16.4 Now the variables look like this --------------------- ....... ipaddr=10.0.5.2 ....... ipaddr=10.0.16.4 ---------------------
=>setenv ipaddr 10.0.28.7 And now the variables look like this --------------------- ....... ....... ipaddr=10.0.16.4 ipaddr=10.0.28.7 ---------------------
Is this the intended behavior? I am running an older version (U-Boot 1.3.4) so maybe this has been fixed. If this is the case could you point me to the version that it is fixed in.
Thanks.
