Hello,
I am trying to bring up a 860T based board using
viper as a template. My code seems to be crashing
when trying to enable the MMU. (see assembly
dump below) I have seen some
talk about this in the archives, but I am still
unclear what was happening there and if I am
seeing the same thing.
Help please!
Thanks,
Mike
