I do - need to attach to a dead/crashed system without reset, aka: “a soft attach” - no reset. Because you need to figure out why things have crashed, various bus clocks may be disabled in parts of the chip, the debugger should not make things worse by probing hardware that is currently disabled due to a power down setting. Meaning: You might be debugging a power down/power up problem. The only thing you know is alive and functional is the debug access port, and the cpu you want to debug specific access port on the DAP you have no idea what the other internal structure of the chip may or may not be. The other CPUs on the target board may also be shut down or held in reset or likewise. ------------------------------------------------------------------------------ "Accelerate Dev Cycles with Automated Cross-Browser Testing - For FREE Instantly run your Selenium tests across 300+ browser/OS combos.
