hi
a 'go' without a previous 'load' command
tries to start a program at 0x00000000.
Mostly there is no executable there
and RedBoot shows me
$T0f40:ff0133c8;01:0003eb6c;#ea
If this is not intended behaviour,
maybe RedBoot
1) should prevent me starting any programm
at 0x00000000.
or
2) should initialize the entry_address with
its rom entry point (e.g. 0xfe000100)
what do you think about that?
regards christoph

If we added copious error checking in RedBoot to deal with every
eventuality that _might_ happen, RedBoot would be a lot bigger and bloated.
If you do something wrong, expect it to go wrong :-).
