Thank you, Ofir. So, for my understanding, updating of boot and BinLib is only required when switching between big release steps (eg. Visilogic v.8. to v.9. or v.7. to v.8. or vice versa). In other case (VisiLogic v.8.1.0.1 to v.8.6.0.1) cloning via SD supposed to work without any complain. Is this correct?
