Cannot get the peripheral example to work anymore

Hello,

I can't run the peripheral example anymore on the development kit. I have done this earlier with old SDK, but now I tried to do it again with 3.0.6 but it's not working. I enter the debug mode and press "Run", but it seems that the execution stops immediately. Then I need to click the Run again and again

Could this affect?
**JLink Warning: T-bit of XPSR is 0 but should be 1. Changed to 1.

Or this?
