Welcome

I have got a problem with my new ST7FLITE29 on EVBST7-02

and programmer ICPCable I (STICK compatibility)

In STVP 1.9.2 configuration i have choosen a STICK -> LPT1 -> ICP OPT Disable -> ST7FLITE29

All was OK, i was can read and program microprocessor, but in next programming i uncheck the two options in STVP :

''Protect RC Calibration values on Program memory'' and

''Protect RC Calibration values on Data Memory''

And now while i want read or program microprocessor, program display a error : ''Error on Option Bytes(complementary bytes)Reprogram Option Bytes of device''

How to restore the fabrique Option Bytes ???

I'm begginer in microprocessor programming and i want easy tips to reapir it.

P.S I'm not english native speaker, because i learn english, sorry :(
