Issue: After downloading an application, J-Link is not able to connect to the CPU

This can have different reasons:

  • Application disables the debug interface
  • Application reconfigures debug pins
  • Application enters some kind of low power mode
  • etc....

Prevent: 

 Delay of 1 second at the start of a debug session, so in any case J-Link can halt the CPU before executing the "bad code"
