Hi,

I just tested it and it works on my side. I used the same example, I programmed it several times by PE, tried to do power off-on and it still works.

It really shouldn't be related to the security. As I already mentioned, that's standard message when PE can't enter debug mode for some reasons. Was that brand new board? Did you check the ribbon cable between PE and the board? Can you program another board?

Hi,

it doesn't sound like problem with the security, it's rather general message that the debugger can't establish the connection. I will try to check it on my board tomorrow. I will let you know my findings.
