ARM_FEATURE_THUMB1 is a bad name for this. Thumb-1 covers both v4t and v5t. Thumb-2 is a completely new architecture revision which adds 32-bit instructions. You should add/use ARM_FEATURE_V5/ARCH(5) instead. For added confusion some older documentation refers to v5t as "thumb2", or the second revision of the Thumb ISA. This should be ignored :-) The ARM7TDMI implements the base updated abort model. You should either implement that, or pick a core (eg. 920t) that uses the base restored abort model. Paul
