I was just expecting the 'invalidate protect' to actually do that. :-) I set up several TLB1 entries during the BDI initialization prior to debugging the boot rom. The boot rom then does a flash invalidate and loads up a "new" set of TLB1 entries. I was expecting the values I set with the BDI to co-exist with the new ones, but that doesn't seem to be the case.
