[OpenOCD-devel] Executing a factory reset from within OpenOCD

[Fewell, E. <ef...@ti...>]

I'm currently finishing up creating flash loader code for the Texas Instruments MSP432p4 device. One feature we want to implement is a factory reset.  Triggering the factory reset involves a sequence of register writes to the device, but then debug must be shut down, the device power-cycled, and then debug can re-connect to the target.

Is that possible from within the context of flash code within the OpenOCD structure?  To disconnect debug, tell the user to power-cycle the device, and then re-connect debug?  At the moment, all I can do is tell the user they need to power-cycle the device and force OpenOCD to exit. Then the user must restart OpenOCD manually.  If I leave OpenOCD running, that causes multiple errors because the target is no longer in a debuggable state.
