Hello.

I am going to write IAP bootloader. To erase/write flash i need 12v on Vpp/ICCSEL pin. By the way i use SofTec inDART-STX/D that uses the same pin for its own purposes. As i determined, debugger puts 12v on this pin during erase/write at the beggining of debug session. I am not so crazy 🙂 to develop bootloader without debuger. Is there any possibilities to have both debugger and 12v and not to damage debugger?

The easiest way is to use switch to connect/disconnect debugger and 12v.

Any another ideas?

What about to use Schotky Diode in between your application and InDART?

Maybe BAR43C could be nice, dual schotky in one package - one for InDART, one for your application....'?
