Where is the "Debug Authencication" ?

[MQi.1]

I used a MB2032-WB09-B02 on MB1801D for several times, flash in CubeIDE was always OK, though debug prompted error read data every time, then the next day when I used it again, it didn't work, I couldn't flash image into neither in IDE nor Prog, the prompt:

my question is: how to discovery using Debug Authentication?

Hello @MQi.1 ,

Check the solder-bridges and jumpers positions (JP2 ON, JP1 on USB_STLK [1-2] on the MB1801 board.)

Switch SW1 should be on the 3V3 power supply (switch on position [1-2]) on the MB1801 board.

Make sure to follow the settings described in the UM3345 STM32WB09 Nucleo-64 board (MB1801 and MB2032) in Getting started section and Table 12. Solder bridges for MB1801.
