Hi,

The most likely cause is that the firmware went to Power-off or to Deep Power Down. In these two power modes, the Debug HW block is not powered and access via SWD is not possible.

Use the define APP_MAINTAIN_SWD_CONNECTION in maintlogger.c and rebuild. This will avoid these two power modes, at the expense of a much higher current consumption.

Best,
Dries.

Had same message and screen w/ LPC1769 OM13085 - but only in release version, not in debug version of same code. Also, not with OM13000 board.

I tweeked Release in Debug Configurations / Debugger (Set VECTRESET, det support for semihosting) and it runs again
